+.Sh NAME
+.Nm apply
+.Nd apply a command to a set of arguments
+.Sh SYNOPSIS
+.Nm
+.Op Fl a Ns Ar c
+.Op Fl Ns Ar #
+.Ar command argument ...
+.Sh DESCRIPTION
+.Nm
+runs the named
+.Ar command
+on each
+argument
+.Ar argument
+in turn.
+.Pp
+Character sequences of the form
+.Dq Li \&%d
+in
+.Ar command ,
+where
+.Dq Li d
+is a digit from 1 to 9, are replaced by the
+.Li d Ns \'th
+following unused
+.Ar argument .
+In this case, the largest digit number of arguments are discarded for
+each execution of
+.Ar command .
+.Pp
+The options are as follows:
+.Bl -tag -width "-ac"
+.It Fl Ns Ar #
+Normally arguments are taken singly; the optional number
+.Fl #
+specifies the number of arguments to be passed to
+.Ar command .
+If the number is zero,
+.Ar command
+is run, without arguments, once for each
+.Ar argument .
+.Pp
+If any sequences of
+.Dq Li \&%d
+occur in command, the
+.Fl #
+option is ignored.
+.It Fl a Ns Ar c
+The use of the character
+.Dq Li %
+as a magic character may be changed with the
+.Fl a
+option.
+.El
+.Sh ENVIRONMENT VARIABLES
+The following environment variable affects the execution of
+.Nm
+:
+.Bl -tag -width SHELL
+.It Ev SHELL
+Pathname of shell to use.
+If this variable is not defined, the Bourne shell is used.
+.El
+.Sh EXAMPLES
+.Bl -tag -width apply -compact
+.It Li "apply echo a*"
+is similar to
+.Xr ls 1 ;
+.It Li "apply \-2 cmp a1 b1 a2 b2 a3 b3"
+compares the `a' files to the `b' files;
+.It Li "apply \-0 who 1 2 3 4 5"
+runs
+.Xr who 1
+5 times; and
+.It Li "apply \'ln %1 /usr/joe\'" *
+links all files in the current directory to the directory
+.Pa /usr/joe .
+.El
+.Sh Files
+.Bl -tag -width /bin/sh -compact
+.It Pa /bin/sh
+Default shell
+.El
+.Sh AUTHOR
+Rob Pike
+.Sh BUGS
+Shell metacharacters in
+.Ar command
+may have bizarre effects; it is best to enclose complicated
+commands in single quotes
+.Pq '' .
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .

+.Sh SYNOPSIS
+.Nm
+.Op Fl nu
+.Op Fl r Ar seconds
+.Op Cm + Ns Ar format
+.Nm ""
+.Ar [[[[[cc]yy]mm]dd]hh]mm[\&.ss]
+.Sh DESCRIPTION
+.Nm
+displays the current date and time when invoked without arguments.
+Providing arguments will format the date and time in a user-defined
+way or set the date.
+Only the superuser may set the date.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl n
+The utility
+.Xr timed 8
+is used to synchronize the clocks on groups of machines.
+By default, if
+timed
+is running,
+.Nm
+will set the time on all of the machines in the local group.
+The
+.Fl n
+option stops
+.Nm
+from setting the time for other than the current machine.
+.It Fl r
+Print out the date and time that is
+.Ar seconds
+from the Epoch.
+.It Fl u
+Display or set the date in
+.Tn UTC
+(universal) time.
+.El
+.Pp
+An operand with a leading plus (``+'') sign signals a user-defined format
+string which specifies the format in which to display the date and time.
+The format string may contain any of the conversion specifications described
+in the
+.Xr strftime 3
+manual page, as well as any arbitrary text.
+A <newline> character is always output after the characters specified by
+the format string.
+The format string for the default display is:
+.Bd -literal -offset indent
+``%a %b %e %H:%M:%S %Z %Y''.
+.Ed
+.Pp
+If an operand does not have a leading plus sign, it is interpreted as
+a value for setting the system's notion of the current date and time.
+The canonical representation for setting the date and time is:
+.Pp
+.Bl -tag -width Ds -compact -offset indent
+.It Ar cc
+The first two digits of the year (the century).
+.It Ar yy
+The second two digits of the year. If
+.Dq yy
+is specified, but
+.Dq cc
+is not, a value for
+.Dq yy
+between 69 and 99 results in a
+.Dq cc
+value of 19. Otherwise, a
+.Dq cc
+value of 20 is used.
+.It Ar mm
+The month of the year, from 1 to 12.
+.It Ar dd
+The day of the month, from 1 to 31.
+.It Ar hh
+The hour of the day, from 0 to 23.
+.It Ar mm
+The minute of the hour, from 0 to 59.
+.It Ar ss
+The second of the minute, from 0 to 61.
+.El
+.Pp
+Everything but the minutes is optional.
+.Pp
+Time changes for Daylight Saving and Standard time and leap seconds
+and years are handled automatically.
+.Sh EXAMPLES
+The command:
+.Bd -literal -offset indent
+date ``+DATE: %m/%d/%y%nTIME: %H:%M:%S''
+.Ed
+.Pp
+will display:
+.Bd -literal -offset indent
+DATE: 11/21/87
+TIME: 13:36:16
+.Ed
+.Pp
+The command:
+.Bd -literal -offset indent
+date 8506131627
+.Ed
+.Pp
+sets the date to
+.Dq Li "June 13, 1985, 4:27 PM" .
+.Pp
+The command:
+.Bd -literal -offset indent
+date 1432
+.Ed
+.Pp
+sets the time to
+.Li "2:32 PM" ,
+without modifying the date.
+.Sh ENVIRONMENT VARIABLES
+The following environment variables affect the execution of
+.Nm
+:
+.Bl -tag -width TZ
+.It Ev TZ
+The timezone to use when displaying dates.
+See
+.Xr environ 7
+for more information.
+.El
+.Sh FILES
+.Bl -tag -width /var/log/messages -compact
+.It Pa /var/log/wtmp
+A record of date resets and time changes.
+.It Pa /var/log/messages
+A record of the user setting the time.

+.%A S. Zatti
+.Re
+.Sh DIAGNOSTICS
+Exit status is 0 on success, 1 if unable to set the date, and 2
+if able to set the local date, but unable to set it globally.
+.Pp
+Occasionally, when
+.Xr timed 8
+synchronizes the time on many hosts, the setting of a new time value may
+require more than a few seconds.
+On these occasions,
+.Nm
+prints:
+.Ql Network time being set .
+The message
+.Ql Communication error with timed
+occurs when the communication
+between
+.Nm
+and
+timed
+fails.
+.Sh STANDARDS
+The

+.Sh SYNOPSIS
+.Nm
+.Ar expression
+.Sh DESCRIPTION
+The
+.Nm
+utility evaluates
+.Ar expression
+and writes the result on standard output.
+.Pp
+All operators are separate arguments to the
+.Nm
+utility.
+Characters special to the command interpreter must be escaped.
+.Pp
+Operators are listed below in order of increasing precedence.
+Operators with equal precedence are grouped within { } symbols.
+.Bl -tag -width indent
+.It Ar expr1 Li | Ar expr2
+Returns the evaluation of
+.Ar expr1
+if it is neither an empty string nor zero;
+otherwise, returns the evaluation of
+.Ar expr2 .
+.It Ar expr1 Li & Ar expr2
+Returns the evaluation of
+.Ar expr1
+if neither expression evaluates to an empty string or zero;
+otherwise, returns zero.
+.It Ar expr1 Li "{=, >, >=, <, <=, !=}" Ar expr2
+Returns the results of integer comparison if both arguments are integers;
+otherwise, returns the results of string comparison using the locale-specific
+collation sequence.
+The result of each comparison is 1 if the specified relation is true,
+or 0 if the relation is false.
+.It Ar expr1 Li "{+, -}" Ar expr2
+Returns the results of addition or subtraction of integer-valued arguments.
+.It Ar expr1 Li "{*, /, %}" Ar expr2
+Returns the results of multiplication, integer division, or remainder of integer-valued arguments.
+.It Ar expr1 Li : Ar expr2
+The
+.Dq \:
+operator matches
+.Ar expr1
+against
+.Ar expr2 ,
+which must be a regular expression. The regular expression is anchored
+to the beginning of the string with an implicit
+.Dq ^ .
+.Pp
+If the match succeeds and the pattern contains at least one regular
+expression subexpression
+.Dq "\e(...\e)" ,
+the string corresponding to
+.Dq "\e1"
+is returned;
+otherwise the matching operator returns the number of characters matched.
+If the match fails and the pattern contains a regular expression subexpression
+the null string is returned;
+otherwise 0.
+.El
+.Pp
+Parentheses are used for grouping in the usual manner.
+.Sh EXAMPLES
+.Bl -enum
+.It
+The following example adds one to the variable a.
+.Dl a=`expr $a + 1`
+.It
+The following example returns the filename portion of a pathname stored
+in variable a. The // characters act to eliminate ambiguity with the
+division operator.
+.Dl expr "//$a" Li : '.*/\e(.*\e)'
+.It
+The following example returns the number of characters in variable a.
+.Dl expr $a Li : '.*'
+.El
+.Sh DIAGNOSTICS
+The
+.Nm
+utility exits with one of the following values:
+.Bl -tag -width Ds -compact
+.It 0
+the expression is neither an empty string nor 0.
+.It 1
+the expression is an empty string or 0.
+.It 2
+the expression is invalid.
+.El
+.Sh STANDARDS
+The
+.Nm
+utility conforms to

+those of the file referenced by the link, not the link itself.
+If the referenced file does not exist, the file information and type will
+be for the link itself. File information of all symbolic links not on
+the command line is that of the link itself.
+.It Fl L
+The
+.Fl L
+option causes the file information and file type (see
+.Xr stat 2)
+returned for each symbolic link to be those of the file referenced by the
+link, not the link itself.
+If the referenced file does not exist, the file information and type will
+be for the link itself.
+.It Fl P
+The
+.Fl P
+option causes the file information and file type (see
+.Xr stat 2)
+returned for each symbolic link to be those of the link itself.
+.It Fl X
+The
+.Fl X
+option is a modification to permit
+.Nm
+to be safely used in conjunction with
+.Xr xargs 1 .
+If a file name contains any of the delimiting characters used by
+.Xr xargs ,
+a diagnostic message is displayed on standard error, and the file
+is skipped.
+The delimiting characters include single (`` ' '') and double (`` " '')
+quotes, backslash (``\e''), space, tab and newline characters.
+.It Fl d
+The
+.Fl d
+option causes
+.Nm
+to perform a depth\-first traversal, i.e. directories
+are visited in post\-order and all entries in a directory will be acted
+on before the directory itself.
+By default,
+.Nm
+visits directories in pre\-order, i.e. before their contents.
+Note, the default is
+.Ar not
+a breadth\-first traversal.
+.It Fl f
+The
+.Fl f
+option specifies a file hierarchy for
+.Nm
+to traverse.
+File hierarchies may also be specified as the operands immediately
+following the options.
+.It Fl h
+The
+.Fl h
+option causes the file information and file type (see
+.Xr stat 2 ) ,
+returned for each symbolic link to be those of the file referenced by the
+link, not the link itself.
+If the referenced file does not exist, the file information and type will
+be for the link itself.
+.It Fl x
+The
+.Fl x
+option prevents
+.Nm
+from descending into directories that have a device number different
+than that of the file from which the descent began.
+.El
+.Sh PRIMARIES
+.Bl -tag -width Ds
+.It Ic -atime Ar n
+True if the difference between the file last access time and the time
+.Nm
+was started, rounded up to the next full 24\-hour period, is
+.Ar n
+24\-hour periods.
+.It Ic -ctime Ar n
+True if the difference between the time of last change of file status
+information and the time
+.Nm
+was started, rounded up to the next full 24\-hour period, is
+.Ar n
+24\-hour periods.
+.It Ic -exec Ar utility Op argument ... ;
+True if the program named
+.Ar utility
+returns a zero value as its exit status.
+Optional arguments may be passed to the utility.
+The expression must be terminated by a semicolon (``;'').
+If the string ``{}'' appears anywhere in the utility name or the
+arguments it is replaced by the pathname of the current file.
+.Ar Utility
+will be executed from the directory from which
+.Nm
+was executed.
+.It Ic -follow
+Follow symbolic links.
+.It Ic -fstype Ar type
+True if the file is contained in a file system of type
+.Ar type .
+The
+.Xr sysctl 8
+command can be used to find out the types of filesystems
+that are available on the system:
+.Bd -literal -offset indent
+sysctl vfs
+.Ed
+In addition, there are two pseudo-types, ``local'' and ``rdonly''.
+The former matches any file system physically mounted on the system where
+the
+.Nm
+is being executed, and the latter matches any file system which is
+mounted read-only.
+.It Ic -group Ar gname
+True if the file belongs to the group
+.Ar gname .
+If
+.Ar gname
+is numeric and there is no such group name, then
+.Ar gname
+is treated as a group id.
+.It Ic -inum Ar n
+True if the file has inode number
+.Ar n .
+.It Ic -links Ar n
+True if the file has
+.Ar n
+links.
+.It Ic -ls
+This primary always evaluates to true.
+The following information for the current file is written to standard output:
+its inode number, size in 512\-byte blocks, file permissions, number of hard
+links, owner, group, size in bytes, last modification time, and pathname.
+If the file is a block or character special file, the major and minor numbers
+will be displayed instead of the size in bytes.
+If the file is a symbolic link, the pathname of the linked\-to file will be
+displayed preceded by ``\->''.
+The format is identical to that produced by ``ls \-dgils''.
+.It Ic -mtime Ar n
+True if the difference between the file last modification time and the time
+.Nm
+was started, rounded up to the next full 24\-hour period, is
+.Ar n
+24\-hour periods.
+.It Ic \&-ok Ar utility Op argument ... ;
+The
+.Ic \&-ok
+primary is identical to the
+.Ic -exec
+primary with the exception that
+.Nm
+requests user affirmation for the execution of the utility by printing
+a message to the terminal and reading a response.
+If the response is other than ``y'' the command is not executed and the
+value of the
+.Ar \&ok
+expression is false.
+.It Ic -name Ar pattern
+True if the last component of the pathname being examined matches
+.Ar pattern .
+Special shell pattern matching characters (``['', ``]'', ``*'', and ``?'')
+may be used as part of
+.Ar pattern .
+These characters may be matched explicitly by escaping them with a
+backslash (``\e'').
+.It Ic -newer Ar file
+True if the current file has a more recent last modification time than
+.Ar file .
+.It Ic -nouser
+True if the file belongs to an unknown user.
+.It Ic -nogroup
+True if the file belongs to an unknown group.
+.It Ic -path Ar pattern
+True if the pathname being examined matches
+.Ar pattern .
+Special shell pattern matching characters (``['', ``]'', ``*'', and ``?'')
+may be used as part of
+.Ar pattern .
+These characters may be matched explicitly by escaping them with a
+backslash (``\e'').
+Slashes (``/'') are treated as normal characters and do not have to be
+matched explicitly.
+.It Ic -perm Op Fl Ns Ar mode
+The
+.Ar mode
+may be either symbolic (see
+.Xr chmod 1 )
+or an octal number.
+If the mode is symbolic, a starting value of zero is assumed and the
+mode sets or clears permissions without regard to the process' file mode
+creation mask.
+If the mode is octal, only bits 07777
+.Pf ( Dv S_ISUID
+|
+.Dv S_ISGID
+|
+.Dv S_ISTXT
+|
+.Dv S_IRWXU
+|
+.Dv S_IRWXG
+|
+.Dv S_IRWXO )
+of the file's mode bits participate
+in the comparison.
+If the mode is preceded by a dash (``\-''), this primary evaluates to true
+if at least all of the bits in the mode are set in the file's mode bits.
+If the mode is not preceded by a dash, this primary evaluates to true if
+the bits in the mode exactly match the file's mode bits.
+Note, the first character of a symbolic mode may not be a dash (``\-'').
+.It Ic -print
+This primary always evaluates to true.
+It prints the pathname of the current file to standard output, followed
+by a newline character.
+If none of
+.Ic -exec ,
+.Ic -ls ,
+.Ic -ok ,
+nor
+.Ic -print0
+is specified, the given expression shall be effectively replaced by
+.Cm \&( Ns Ar given\& expression Ns Cm \&)
+.Ic -print .
+.It Ic -print0
+This primary always evaluates to true.
+It prints the pathname of the current file to standard output, followed
+by a null character.
+.It Ic -prune
+This primary always evaluates to true.
+It causes
+.Nm
+to not descend into the current file.
+Note, the
+.Ic -prune
+primary has no effect if the
+.Fl d
+option was specified.
+.It Ic -size Ar n Ns Op Cm c
+True if the file's size, rounded up, in 512\-byte blocks is
+.Ar n .
+If
+.Ar n
+is followed by a ``c'', then the primary is true if the
+file's size is
+.Ar n
+bytes.
+.It Ic -type Ar t
+True if the file is of the specified type.
+Possible file types are as follows:
+.Pp
+.Bl -tag -width flag -offset indent -compact
+.It Cm W
+whiteout
+.It Cm b
+block special
+.It Cm c
+character special
+.It Cm d
+directory
+.It Cm f
+regular file
+.It Cm l
+symbolic link
+.It Cm p
+FIFO
+.It Cm s
+socket
+.El
+.Pp
+.It Ic -user Ar uname
+True if the file belongs to the user
+.Ar uname .
+If
+.Ar uname
+is numeric and there is no such user name, then
+.Ar uname
+is treated as a user id.
+.El
+.Pp
+All primaries which take a numeric argument allow the number to be
+preceded by a plus sign (``+'') or a minus sign (``\-'').
+A preceding plus sign means ``more than n'', a preceding minus sign means
+``less than n'' and neither means ``exactly n'' .
+.Sh OPERATORS
+The primaries may be combined using the following operators.
+The operators are listed in order of decreasing precedence.
+.Bl -tag -width (expression)
+.It Cm \&( Ns Ar expression Ns Cm \&)
+This evaluates to true if the parenthesized expression evaluates to
+true.
+.Pp
+.It Cm \&! Ns Ar expression
+This is the unary
+.Tn NOT
+operator.
+It evaluates to true if the expression is false.
+.Pp
+.It Ar expression Cm -and Ar expression
+.It Ar expression expression
+The
+.Cm -and
+operator is the logical
+.Tn AND
+operator.
+As it is implied by the juxtaposition of two expressions it does not
+have to be specified.
+The expression evaluates to true if both expressions are true.
+The second expression is not evaluated if the first expression is false.
+.Pp
+.It Ar expression Cm -or Ar expression
+The
+.Cm -or
+operator is the logical
+.Tn OR
+operator.
+The expression evaluates to true if either the first or the second expression
+is true.
+The second expression is not evaluated if the first expression is true.
+.El
+.Pp
+All operands and primaries must be separate arguments to
+.Nm "" .
+Primaries which themselves take arguments expect each argument
+to be a separate argument to
+.Nm "" .
+.Sh EXAMPLES
+.Pp
+The following examples are shown as given to the shell:
+.Bl -tag -width findx
+.It Li "find / \e! -name \*q*.c\*q -print"
+Print out a list of all the files whose names do not end in ``.c''.
+.It Li "find / -newer ttt -user wnj -print"
+Print out a list of all the files owned by user ``wnj'' that are newer
+than the file ``ttt''.
+.It Li "find / \e! \e( -newer ttt -user wnj \e) -print"
+Print out a list of all the files which are not both newer than ``ttt''
+and owned by ``wnj''.
+.It Li "find / \e( -newer ttt -or -user wnj \e) -print"
+Print out a list of all the files that are either owned by ``wnj'' or
+that are newer than ``ttt''.

+.Sh STANDARDS
+The
+.Nm
+utility syntax is a superset of the syntax specified by the
+.St -p1003.2
+standard.
+.Pp
+The options and the
+.Ic -follow ,
+.Ic -fstype ,
+.Ic -inum ,
+.Ic -links ,
+.Ic -ls
+and
+.Ic -print0
+primaries are extensions to
+.St -p1003.2 .
+.Pp
+Historically, the
+.Fl d ,
+.Fl h
+and
+.Fl x
+options were implemented using the primaries ``\-depth'', ``\-follow'',
+and ``\-xdev''.
+These primaries always evaluated to true.
+As they were really global variables that took effect before the traversal
+began, some legal expressions could have unexpected results.
+An example is the expression ``\-print \-o \-depth''.
+As \-print always evaluates to true, the standard order of evaluation
+implies that \-depth would never be evaluated.
+This is not the case.
+.Pp
+The operator ``-or'' was implemented as ``\-o'', and the operator ``-and''
+was implemented as ``\-a''.
+.Pp
+Historic implementations of the
+.Ic -exec
+and
+.Ic -ok
+primaries did not replace the string ``{}'' in the utility name or the
+utility arguments if it had preceding or following non-whitespace characters.
+This version replaces it no matter where in the utility name or arguments
+it appears.
+.Sh BUGS
+The special characters used by
+.Nm
+are also special characters to many shell programs.
+In particular, the characters ``*'', ``['', ``]'', ``?'', ``('', ``)'',
+``!'', ``\e'' and ``;'' may have to be escaped from the shell.
+.Pp
+As there is no delimiter separating options and file names or file
+names and the
+.Ar expression ,
+it is difficult to specify files named ``-xdev'' or ``!''.
+These problems are handled by the
+.Fl f
+option and the
+.Xr getopt 3
+``--'' construct.

+.Dd June 21, 1993
+.Dt GETOPT 1
+.Os
+.Sh NAME
+.Nm getopt
+.Nd parse command options
+.Sh SYNOPSIS
+.Li args=\`getopt optstring $*\`
+.Pp
+.Li set \-\- \`getopt optstring $*\`
+.Sh DESCRIPTION
+.Nm
+is used to break up options in command lines for easy parsing by
+shell procedures, and to check for legal options.
+.Op Optstring
+is a string of recognized option letters (see
+.Xr getopt 3
+);
+if a letter is followed by a colon, the option
+is expected to have an argument which may or may not be
+separated from it by white space.
+The special option
+.Dq \-\-
+is used to delimit the end of the options.
+.Nm
+will place
+.Dq \-\-
+in the arguments at the end of the options,
+or recognize it if used explicitly.
+The shell arguments
+(\fB$1 $2\fR ...) are reset so that each option is
+preceded by a
+.Dq \-
+and in its own shell argument;
+each option argument is also in its own shell argument.
+.Sh EXAMPLE
+The following code fragment shows how one might process the arguments
+for a command that can take the options
+.Op a
+and
+.Op b ,
+and the option
+.Op o ,
+which requires an argument.
+.Pp
+.Bd -literal -offset indent
+args=\`getopt abo: $*\`
+if test $? != 0
+then
+ echo 'Usage: ...'
+ exit 2
+fi
+set \-\- $args
+for i
+do
+ case "$i"
+ in
+ \-a|\-b)
+ flag=$i; shift;;
+ \-o)
+ oarg=$2; shift; shift;;
+ \-\-)
+ shift; break;;
+ esac
+done
+.Ed
+.Pp
+This code will accept any of the following as equivalent:
+.Pp
+.Bd -literal -offset indent
+cmd \-aoarg file file
+cmd \-a \-o arg file file
+cmd \-oarg -a file file
+cmd \-a \-oarg \-\- file file
+.Ed
+.Pp
+.St -p1003.2
+mandates that the
+.Xr sh 1
+set command return the value of 0 for the exit status. Therefore,
+the exit status of the
+.Nm
+command is lost when
+.Nm
+and the
+.Xr sh 1
+set command are used on the same line. The example given
+is one way to detect errors found by
+.Nm "" .
+.Sh SEE ALSO
+.Xr sh 1 ,
+.Xr getopt 3
+.Sh DIAGNOSTICS
+.Nm
+prints an error message on the standard error output when it
+encounters an option letter not included in
+.Op optstring .
+.Sh HISTORY
+Written by Henry Spencer, working from a Bell Labs manual page.
+Behavior believed identical to the Bell version.
+.Sh BUGS
+Whatever
+.Xr getopt 3
+has.
+.Pp
+Arguments containing white space or embedded shell metacharacters
+generally will not survive intact; this looks easy to fix but isn't.
+.Pp
+The error message for an invalid option is identified as coming
+from
+.Nm
+rather than from the shell procedure containing the invocation
+of
+.Nm "" ;
+this again is hard to fix.
+.Pp
+The precise best way to use the
+.Ic set
+command to set the arguments without disrupting the value(s) of
+shell options varies from one shell version to another.

+.Nm jot
+.Op Fl rcn

+.Op Fl s Ar string
+.Op Fl p Ar precision
+.Oo Ar reps
+.Oo Ar begin
+.Oo Ar end
+.Op Ar s

+.Sh DESCRIPTION
+The
+.Nm jot
+utility is used to print out increasing, decreasing, random,
+or redundant data (usually numbers) one per line.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl r
+Generate random data instead of sequential data, the default.
+.It Fl b Ar word
+Just print
+.Ar word
+repetitively.
+.It Fl w Ar word
+Print
+.Ar word
+with the generated data appended to it.
+Octal, hexadecimal, exponential, ASCII, zero padded,
+and right-adjusted representations
+are possible by using the appropriate
+.Xr printf 3
+conversion specification inside
+.Ar word ,
+in which case the data are inserted rather than appended.
+.It Fl c
+This is an abbreviation for \fB\-w %c\fP.
+.It Fl s Ar string
+Print data separated by
+.Ar string .
+Normally, newlines separate data.
+.It Fl n
+Do not print the final newline normally appended to the output.
+.It Fl p Ar precision
+Print only as many digits or characters of the data
+as indicated by the integer
+.Ar precision .
+In the absence of
+.Fl p ,
+the precision is the greater of the precisions of
+.Ar begin
+and
+.Ar end .
+The
+.Fl p
+option is overridden by whatever appears in a
+.Xr printf 3
+conversion following
+.Fl w .
+.El
+.Pp
+The last four arguments indicate, respectively,
+the number of data, the lower bound, the upper bound,
+and the step size or, for random data, the seed.
+While at least one of them must appear,
+any of the other three may be omitted, and
+will be considered as such if given as
+.Dq - .
+Any three of these arguments determines the fourth.
+If four are specified and the given and computed values of
+.Ar reps
+conflict, the lower value is used.
+If fewer than three are specified, defaults are assigned
+left to right, except for
+.Ar s ,
+which assumes its default unless both
+.Ar begin
+and
+.Ar end
+are given.
+.Pp
+Defaults for the four arguments are, respectively,
+100, 1, 100, and 1, except that when random data are requested,
+.Ar s
+defaults to a seed depending upon the time of day.
+.Ar reps
+is expected to be an unsigned integer,
+and if given as zero is taken to be infinite.
+.Ar begin
+and
+.Ar end
+may be given as real numbers or as characters
+representing the corresponding value in ASCII.
+The last argument must be a real number.
+.Pp
+Random numbers are obtained through
+.Xr random 3 .
+The name
+.Nm jot
+derives in part from
+.Nm iota ,
+a function in APL.
+.Sh EXAMPLES
+The command:
+.Dl "jot 21 \-1 1.00"
+prints 21 evenly spaced numbers increasing from \-1 to 1.
+.Pp
+The command:
+.Dl "jot \-c 128 0"
+prints the ASCII character set.
+.Pp
+The command:
+.Dl "jot \-w xa%c 26 a"
+prints the strings
+.Dq xaa
+through
+.Dq xaz .
+.Pp
+The command:
+.Dl "jot \-r \-c 160 a z | rs \-g 0 8"
+prints 20 random 8-letter strings.
+.Pp
+The command:
+.Dl "jot \-b y 0"
+is equivalent to
+.Xr yes 1 .
+.Pp
+The command:
+.Dl "jot \-w %ds/old/new/ 30 2 \- 5"
+prints thirty
+.Xr ed 1
+substitution commands applying to lines 2, 7, 12, etc.
+.Pp
+The command:
+.Dl "jot 0 9 \- \-.5"
+prints the stuttering sequence 9, 9, 8, 8, 7, etc.
+.Pp
+The command:
+.Dl "jot \-b x 512 > block"
+creates a file containing exactly 1024 bytes.
+.Pp
+The command:
+.Dl "expand \-\`jot \-s, \- 10 132 4\`"
+sets tabs four spaces apart starting
+from column 10 and ending in column 132.
+.Pp
+The command:
+.Dl "grep \`jot \-s """" \-b . 80\`"
+prints all lines 80 characters or longer.

+.Nm kill
+.Nd terminate or signal a process
+.Sh SYNOPSIS
+.Nm
+.Op Fl s Ar signal_name
+.Ar pid
+\&...
+.Nm ""
+.Fl l
+.Op Ar exit_status
+.Nm ""
+.Fl signal_name
+.Ar pid
+\&...

+.Fl signal_number
+.Ar pid
+\&...
+.Sh DESCRIPTION
+The kill utility sends a signal to the processes specified
+by the pid operand(s).
+.Pp
+Only the super-user may send signals to other users' processes.
+.Pp
+The options are as follows:
+.Pp
+.Bl -tag -width Ds
+.It Fl s Ar signal_name
+A symbolic signal name specifying the signal to be sent instead of the
+default
+.Dv TERM .
+.It Fl l Op Ar exit_status
+If no operand is given, list the signal names; otherwise, write
+the signal name corresponding to
+.Ar exit_status .
+.It Fl signal_name
+A symbolic signal name specifying the signal to be sent instead of the
+default
+.Dv TERM .
+.It Fl signal_number
+A non-negative decimal integer, specifying the signal to be sent instead
+of the default
+.Dv TERM .
+.El
+.Pp
+The following pids have special meanings:
+.Bl -tag -width Ds -compact
+.It -1
+If superuser, broadcast the signal to all processes; otherwise broadcast
+to all processes belonging to the user.
+.El
+.Pp
+Some of the more commonly used signals:
+.Bl -tag -width Ds -compact
+.It 1
+HUP (hang up)
+.It 2
+INT (interrupt)
+.It 3
+QUIT (quit)
+.It 6
+ABRT (abort)
+.It 9
+KILL (non-catchable, non-ignorable kill)
+.It 14
+ALRM (alarm clock)
+.It 15
+TERM (software termination signal)
+.El
+.Pp
+.Nm
+is a built-in to
+.Xr csh 1 ;
+it allows job specifiers of the form ``%...'' as arguments
+so process id's are not as often used as
+.Nm
+arguments.
+See
+.Xr csh 1
+for details.
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr ps 1 ,
+.Xr kill 2 ,
+.Xr sigaction 2
+.Sh STANDARDS
+The
+.Nm
+function is expected to be
+.St -p1003.2
+compatible.
+.Sh HISTORY
+A
+.Nm
+command appeared in
+.At v6 .
+.Sh BUGS
+A replacement for the command
+.Dq Li kill 0

+.Op Fl f Ar file
+.Op Ar command ...
+.Op Ar user ...
+.Op Ar terminal ...
+.Sh DESCRIPTION
+.Nm
+gives information on previously executed commands.
+With no arguments,
+.Nm
+prints information about all the commands recorded
+during the current accounting file's lifetime.

+Option:
+.Pp
+.Bl -tag -width Fl
+.It Fl f Ar file

+.El
+.Pp
+If called with arguments, only accounting entries with a
+matching
+.Ar command
+name,
+.Ar user
+name,
+or
+.Ar terminal
+name
+are printed.
+So, for example:
+.Pp
+.Dl lastcomm a.out root ttyd0
+.Pp
+would produce a listing of all the
+executions of commands named
+.Pa a.out
+by user
+.Ar root
+on the terminal
+.Ar ttyd0 .
+.Pp
+For each process entry, the following are printed.
+.Pp
+.Bl -bullet -offset indent -compact
+.It
+The name of the user who ran the process.
+.It
+Flags, as accumulated by the accounting facilities in the system.
+.It
+The command name under which the process was called.
+.It
+The amount of cpu time used by the process (in seconds).
+.It
+The time the process started.
+.It
+The elapsed time of the process.
+.El
+.Pp
+The flags are encoded as follows: ``S'' indicates the command was
+executed by the super-user, ``F'' indicates the command ran after
+a fork, but without a following
+.Xr exec ,
+``C'' indicates the command was run in PDP-11 compatibility mode
+(VAX only),
+``D'' indicates the command terminated with the generation of a
+.Pa core
+file, and ``X'' indicates the command was terminated with a signal.

+ * PURPOSE: sorted list compressor (works with a modified 'find'
+ * to encode/decode a filename database)
+ *
+ * USAGE: bigram < list > bigrams
+ * process bigrams (see updatedb) > common_bigrams
+ * code common_bigrams < list > squozen_list
+ *
+ * METHOD: Uses 'front compression' (see ";login:", Volume 8, Number 1
+ * February/March 1983, p. 8). Output format is, per line, an
+ * offset differential count byte followed by a partially bigram-
+ * encoded ascii residue. A bigram is a two-character sequence,
+ * the first 128 most common of which are encoded in one byte.
+ *
+ * EXAMPLE: For simple front compression with no bigram encoding,
+ * if the input is... then the output is...
+ *
+ * /usr/src 0 /usr/src
+ * /usr/src/cmd/aardvark.c 8 /cmd/aardvark.c
+ * /usr/src/cmd/armadillo.c 14 armadillo.c
+ * /usr/tmp/zoo 5 tmp/zoo
+ *
+ * The codes are:
+ *
+ * 0-28 likeliest differential counts + offset to make nonnegative
+ * 30 switch code for out-of-range count to follow in next word
+ * 128-255 bigram codes (128 most common, as determined by 'updatedb')
+ * 32-127 single character (printable) ascii residue (ie, literal)

+ *
+ * Locate scans a file list for the full pathname of a file given only part
+ * of the name. The list has been processed with with "front-compression"
+ * and bigram coding. Front compression reduces space by a factor of 4-5,
+ * bigram coding by a further 20-25%.
+ *
+ * The codes are:
+ *
+ * 0-28 likeliest differential counts + offset to make nonnegative
+ * 30 switch code for out-of-range count to follow in next word
+ * 128-255 bigram codes (128 most common, as determined by 'updatedb')
+ * 32-127 single character (printable) ascii residue (ie, literal)
+ *
+ * A novel two-tiered string search technique is employed:
+ *
+ * First, a metacharacter-free subpattern and partial pathname is matched
+ * BACKWARDS to avoid full expansion of the pathname list. The time savings
+ * is 40-50% over forward matching, which cannot efficiently handle
+ * overlapped search patterns and compressed path residue.
+ *
+ * Then, the actual shell glob-style regular expression (if in this form) is
+ * matched against the candidate pathnames using the slower routines provided
+ * in the standard 'find'.

+.Sh NAME
+.Nm nice
+.Nd execute a utility with an altered scheduling priority
+.Sh SYNOPSIS
+.Nm
+.Op Fl n Ar increment
+.Ar utility
+.Op Ar argument ...
+.Sh DESCRIPTION
+.Nm
+runs
+.Ar utility
+at an altered scheduling priority.
+If an
+.Ar increment
+is given, it is used; otherwise
+an increment of 10 is assumed.
+The super-user can run utilities with priorities higher than normal by using
+a negative
+.Ar increment .
+The priority can be adjusted over a
+range of -20 (the highest) to 20 (the lowest).
+.Pp
+Available options:
+.Bl -tag -width indent
+.It Fl n Ar increment
+A positive or negative decimal integer used to modify the system scheduling
+priority of
+.Ar utility.
+.El
+.Sh DIAGNOSTICS
+The
+.Nm
+utility shall exit with one of the following values:
+.Bl -tag -width indent
+.It 1-125
+An error occurred in the
+.Nm
+utility.
+.It 126
+The
+.Ar utility
+was found but could not be invoked.
+.It 127
+The
+.Ar utility
+could not be found.
+.El
+.Pp
+Otherwise, the exit status of
+.Nm
+shall be that of
+.Ar utility .
+.Sh COMPATIBILITY
+The historic
+.Fl Ns Ar increment
+option has been deprecated but is still supported in this implementation.
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr getpriority 2 ,
+.Xr setpriority 2 ,
+.Xr renice 8
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.2-92 .
+.Sh HISTORY
+A
+.Nm
+utility appeared in
+.At v6 .
+.Sh BUGS
+.Nm
+is built into
+.Xr csh 1
+with a slightly different syntax than described here. The form
+.Ql nice +10
+nices to positive nice, and
+.Ql nice \-10
+can be used
+by the super-user to give a process more of the processor.

+.Sh NAME

+.Nd formatted output
+.Sh SYNOPSIS
+.Nm
+.Ar format
+.Op Ar arguments ...
+.Sh DESCRIPTION
+.Nm
+formats and prints its arguments, after the first, under control
+of the
+.Ar format .
+The
+.Ar format
+is a character string which contains three types of objects: plain characters,
+which are simply copied to standard output, character escape sequences which
+are converted and copied to the standard output, and format specifications,
+each of which causes printing of the next successive
+.Ar argument .
+.Pp
+The
+.Ar arguments
+after the first are treated as strings if the corresponding format is
+either
+.Cm b ,
+.Cm c
+or
+.Cm s ;
+otherwise it is evaluated as a C constant, with the following extensions:
+.Pp
+.Bl -bullet -offset indent -compact
+.It
+A leading plus or minus sign is allowed.
+.It
+If the leading character is a single or double quote, the value is the
+.Tn ASCII
+code of the next character.
+.El
+.Pp
+The format string is reused as often as necessary to satisfy the
+.Ar arguments .
+Any extra format specifications are evaluated with zero or the null
+string.
+.Pp
+Character escape sequences are in backslash notation as defined in
+.St -ansiC .
+The characters and their meanings
+are as follows:
+.Bl -tag -width Ds -offset indent
+.It Cm \ee
+Write an <escape> character.
+.It Cm \ea
+Write a <bell> character.
+.It Cm \eb
+Write a <backspace> character.
+.It Cm \ef
+Write a <form-feed> character.
+.It Cm \en
+Write a <new-line> character.
+.It Cm \er
+Write a <carriage return> character.
+.It Cm \et
+Write a <tab> character.
+.It Cm \ev
+Write a <vertical tab> character.
+.It Cm \e\'
+Write a <single quote> character.
+.It Cm \e\e
+Write a backslash character.
+.It Cm \e Ns Ar num
+Write an 8-bit character whose
+.Tn ASCII
+value is the 1-, 2-, or 3-digit
+octal number
+.Ar num .
+.El
+.Pp
+Each format specification is introduced by the percent character
+(``%'').
+The remainder of the format specification includes,
+in the following order:
+.Bl -tag -width Ds
+.It "Zero or more of the following flags:"
+.Bl -tag -width Ds
+.It Cm #
+A `#' character
+specifying that the value should be printed in an ``alternative form''.
+For
+.Cm c ,
+.Cm d ,
+and
+.Cm s ,
+formats, this option has no effect. For the
+.Cm o
+formats the precision of the number is increased to force the first
+character of the output string to a zero. For the
+.Cm x
+.Pq Cm X
+format, a non-zero result has the string
+.Li 0x
+.Pq Li 0X
+prepended to it. For
+.Cm e ,
+.Cm E ,
+.Cm f ,
+.Cm g ,
+and
+.Cm G ,
+formats, the result will always contain a decimal point, even if no
+digits follow the point (normally, a decimal point only appears in the
+results of those formats if a digit follows the decimal point). For
+.Cm g
+and
+.Cm G
+formats, trailing zeros are not removed from the result as they
+would otherwise be;
+.It Cm \&\-
+A minus sign `\-' which specifies
+.Em left adjustment
+of the output in the indicated field;
+.It Cm \&+
+A `+' character specifying that there should always be
+a sign placed before the number when using signed formats.
+.It Sq \&\ \&
+A space specifying that a blank should be left before a positive number
+for a signed format. A `+' overrides a space if both are used;
+.It Cm \&0
+A zero `0' character indicating that zero-padding should be used
+rather than blank-padding. A `\-' overrides a `0' if both are used;
+.El
+.It "Field Width:"
+An optional digit string specifying a
+.Em field width ;
+if the output string has fewer characters than the field width it will
+be blank-padded on the left (or right, if the left-adjustment indicator
+has been given) to make up the field width (note that a leading zero
+is a flag, but an embedded zero is part of a field width);
+.It Precision:
+An optional period,
+.Sq Cm \&.\& ,
+followed by an optional digit string giving a
+.Em precision
+which specifies the number of digits to appear after the decimal point,
+for
+.Cm e
+and
+.Cm f
+formats, or the maximum number of characters to be printed
+from a string; if the digit string is missing, the precision is treated
+as zero;
+.It Format:
+A character which indicates the type of format to use (one of
+.Cm diouxXfwEgGbcs ) .
+.El
+.Pp
+A field width or precision may be
+.Sq Cm \&*
+instead of a digit string.
+In this case an
+.Ar argument
+supplies the field width or precision.
+.Pp
+The format characters and their meanings are:
+.Bl -tag -width Fl
+.It Cm diouXx
+The
+.Ar argument
+is printed as a signed decimal (d or i), unsigned octal, unsigned decimal,
+or unsigned hexadecimal (X or x), respectively.
+.It Cm f
+The
+.Ar argument
+is printed in the style
+.Sm off
+.Pf [\-]ddd Cm \&. No ddd
+.Sm on
+where the number of d's
+after the decimal point is equal to the precision specification for
+the argument.
+If the precision is missing, 6 digits are given; if the precision
+is explicitly 0, no digits and no decimal point are printed.
+.It Cm eE
+The
+.Ar argument
+is printed in the style
+.Sm off
+.Pf [\-]d Cm \&. No ddd Cm e No \\*(Pmdd
+.Sm on
+where there
+is one digit before the decimal point and the number after is equal to
+the precision specification for the argument; when the precision is
+missing, 6 digits are produced.
+An upper-case E is used for an `E' format.
+.It Cm gG
+The
+.Ar argument
+is printed in style
+.Cm f
+or in style
+.Cm e
+.Pq Cm E
+whichever gives full precision in minimum space.
+.It Cm b
+Characters from the string
+.Ar argument
+are printed with backslash-escape sequences expanded.
+.It Cm c
+The first character of
+.Ar argument
+is printed.
+.It Cm s
+Characters from the string
+.Ar argument
+are printed until the end is reached or until the number of characters
+indicated by the precision specification is reached; however if the
+precision is 0 or missing, all characters in the string are printed.
+.It Cm \&%
+Print a `%'; no argument is used.
+.El
+.Pp
+In no case does a non-existent or small field width cause truncation of
+a field; padding takes place only if the specified field width exceeds
+the actual width.
+.Sh RETURN VALUES
+.Nm
+exits 0 on success, 1 on failure.
+.Sh SEE ALSO
+.Xr echo 1 ,
+.Xr printf 3
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.2-92 .
+.Sh BUGS
+Since the floating point numbers are translated from
+.Tn ASCII
+to floating-point and
+then back again, floating-point precision may be lost.

+.Nm
+.Op Fl LP
+.Sh DESCRIPTION
+.Nm
+writes the absolute pathname of the current working directory to

+.Pp
+The
+.Nm
+utility exits 0 on success, and >0 if an error occurs.
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl L
+Print the logical path to the current working directory, as defined
+by the shell in the evironment variable PWD.
+.It Fl P
+Print the physical path to the current working directory, with symbolic
+links in the path resolved. This is the default.
+.El
+.Sh STANDARDS
+The
+.Nm
+utility is expected to be
+.St -p1003.2

+.Xr getcwd 3
+.Sh BUGS
+In
+.Xr csh 1
+the command
+.Ic dirs
+is always faster (although it can give a different answer in the rare case
+that the current directory or a containing directory was moved after
+the shell descended into it).

+.Oo
+.Op Fl g
+.Ar pgrp ...
+.Oc
+.Oo
+.Op Fl u
+.Ar user ...
+.Oc
+.Sh DESCRIPTION
+.Nm
+alters the
+scheduling priority of one or more running processes.
+The following
+.Ar who
+parameters are interpreted as process ID's, process group
+ID's, or user names.
+.Nm "" Ns 'ing
+a process group causes all processes in the process group
+to have their scheduling priority altered.
+.Nm "" Ns 'ing
+a user causes all processes owned by the user to have
+their scheduling priority altered.
+By default, the processes to be affected are specified by
+their process ID's.
+.Pp
+Options supported by
+.Nm "" :
+.Bl -tag -width Ds
+.It Fl g
+Force
+.Ar who
+parameters to be interpreted as process group ID's.
+.It Fl u
+Force the
+.Ar who
+parameters to be interpreted as user names.
+.It Fl p
+Resets the
+.Ar who
+interpretation to be (the default) process ID's.
+.El
+.Pp
+For example,
+.Bd -literal -offset
+renice +1 987 -u daemon root -p 32
+.Ed
+.Pp
+would change the priority of process ID's 987 and 32, and
+all processes owned by users daemon and root.
+.Pp
+Users other than the super-user may only alter the priority of
+processes they own,
+and can only monotonically increase their ``nice value''
+within the range 0 to
+.Dv PRIO_MAX
+(20).
+(This prevents overriding administrative fiats.)
+The super-user
+may alter the priority of any process
+and set the priority to any value in the range
+.Dv PRIO_MIN
+(\-20)
+to
+.Dv PRIO_MAX .
+Useful priorities are:
+20 (the affected processes will run only when nothing else
+in the system wants to),
+0 (the ``base'' scheduling priority),
+anything negative (to make things go very fast).
+.Sh FILES
+.Bl -tag -width /etc/passwd -compact
+.It Pa /etc/passwd
+to map user names to user ID's
+.El
+.Sh SEE ALSO
+.Xr nice 1 ,
+.Xr getpriority 2 ,
+.Xr setpriority 2
+.Sh BUGS
+Non super-users can not increase scheduling priorities of their own processes,
+even if they were the ones that decreased the priorities in the first place.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.0 .

+.Sh NAME
+.Nm script
+.Nd make typescript of terminal session
+.Sh SYNOPSIS
+.Nm
+.Op Fl a
+.Op Ar file
+.Sh DESCRIPTION
+.Nm
+makes a typescript of everything printed on your terminal.
+It is useful for students who need a hardcopy record of an interactive
+session as proof of an assignment, as the typescript file
+can be printed out later with
+.Xr lpr 1 .
+.Pp
+If the argument
+.Ar file
+is given,
+.Nm
+saves all dialogue in
+.Ar file .
+If no file name is given, the typescript is saved in the file
+.Pa typescript .
+.Pp
+Option:
+.Bl -tag -width Ds
+.It Fl a
+Append the output to
+.Ar file
+or
+.Pa typescript ,
+retaining the prior contents.
+.El
+.Pp
+The script ends when the forked shell exits (a
+.Em control-D
+to exit
+the Bourne shell
+.Pf ( Xr sh 1 ) ,
+and
+.Em exit ,
+.Em logout
+or
+.Em control-d
+(if
+.Em ignoreeof
+is not set) for the
+C-shell,
+.Xr csh 1 ) .
+.Pp
+Certain interactive commands, such as
+.Xr vi 1 ,
+create garbage in the typescript file.
+.Nm
+works best with commands that do not manipulate the
+screen, the results are meant to emulate a hardcopy
+terminal.
+.Sh ENVIRONMENT
+The following environment variable is utilized by
+.Nm
+:
+.Bl -tag -width SHELL
+.It Ev SHELL
+If the variable
+.Ev SHELL
+exists, the shell forked by
+.Nm
+will be that shell. If
+.Ev SHELL
+is not set, the Bourne shell
+is assumed. (Most shells set this variable automatically).
+.El
+.Sh SEE ALSO
+.Xr csh 1
+(for the
+.Em history
+mechanism).
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 3.0 .
+.Sh BUGS
+.Nm
+places
+.Sy everything
+in the log file, including linefeeds and backspaces.
+This is not what the naive user expects.

+.Os
+.Sh NAME
+.Nm shlock
+.Nd create or verify a lock file for shell scripts
+.Sh SYNOPSIS
+.Nm
+.Fl f
+.Ar lockfile
+.Op Fl p Ar PID
+.Op Fl u
+.Op Fl v
+.Sh DESCRIPTION
+The
+.Nm
+command can create or verify a lock file on behalf of a shell or
+other script program.
+When it attempts to create a lock file, if one already exists,
+.Nm
+verifies that it is or is not valid.
+If valid,
+.Nm
+will exit with a non-zero exit code.
+If invalid,
+.Nm
+will remove the lock file, and
+create a new one.
+.Pp
+.Nm
+uses the
+.Xr rename 2
+system call to make the final target lock file, which is an atomic
+operation (i.e. "dot locking", so named for this mechanism's original
+use for locking system mailboxes).
+It puts the process ID ("PID") from the command line into the
+requested lock file.
+.Pp
+.Nm
+verifies that an extant lock file is still valid by
+using
+.Xr kill 2
+with a zero signal to check for the existence of the process that
+holds the lock.
+.Pp
+The
+.Fl f
+argument with
+.Ar lockfile
+is always required.
+.Pp
+The
+.Fl p
+option with
+.Ar PID
+is given when the program is to create a lock file; when absent,
+.Nm
+will simply check for the validity of the lock file.
+.Pp
+The
+.Fl u
+option causes
+.Nm
+to read and write the PID as a binary pid_t, instead of as ASCII,
+to be compatible with the locks created by UUCP.
+.Pp
+The
+.Fl v
+option causes
+.Nm
+to be verbose about what it is doing.
+.Sh RETURN VALUES
+A zero exit code indicates a valid lock file.
+.Sh EXAMPLES
+.Ss BOURNE SHELL
+.Bd -literal
+#!/bin/sh
+lckfile=/tmp/foo.lock
+if shlock -f ${lckfile} -p $$
+then
+# do what required the lock
+ rm ${lckfile}
+else
+ echo Lock ${lckfile} already held by `cat ${lckfile}`
+fi
+.Ed
+.Ss C SHELL
+.Bd -literal
+#!/bin/csh -f
+set lckfile=/tmp/foo.lock
+shlock -f ${lckfile} -p $$
+if ($status == 0) then
+# do what required the lock
+ rm ${lckfile}
+else
+ echo Lock ${lckfile} already held by `cat ${lckfile}`
+endif
+.Ed
+
+.Pp
+The examples assume that the filesystem where the lock file is to
+be created is writeable by the user, and has space available.
+.Sh HISTORY
+.Nm
+was written for the first Network News Transfer Protocol (NNTP)
+software distribution, released in March 1986.
+The algorithm was suggested by Peter Honeyman,
+from work he did on HoneyDanBer UUCP.
+.Sh AUTHOR
+Erik E. Fair <fair@clock.org>
+.Sh BUGS
+Does not work on NFS or other network filesystem on different
+systems because the disparate systems have disjoint PID spaces.
+.Pp
+Cannot handle the case where a lock file was not deleted, the
+process that created it has exited, and the system has created a
+new process with the same PID as in the dead lock file.
+The lock file will appear to be valid even though the process is
+unrelated to the one that created the lock in the first place.
+Always remove your lock files after you're done.

+/*
+** Program to produce reliable locks for shell scripts.
+** Algorithm suggested by Peter Honeyman, January 1984,
+** in connection with HoneyDanBer UUCP.
+**
+** I tried extending this to handle shared locks in November 1987,
+** and ran into to some fundamental problems:
+**
+** Neither 4.3 BSD nor System V have an open(2) with locking,
+** so that you can open a file and have it locked as soon as
+** it's real; you have to make two system calls, and there's
+** a race...
+**
+** When removing dead process id's from a list in a file,
+** you need to truncate the file (you don't want to create a
+** new one; see above); unfortunately for the portability of
+** this program, only 4.3 BSD has ftruncate(2).
+**
+** Erik E. Fair <fair@ucbarpa.berkeley.edu>, November 8, 1987
+**
+** Extensions for UUCP style locks (i.e. pid is an int in the file,
+** rather than an ASCII string). Also fix long standing bug with
+** full file systems and temporary files.
+**
+** Erik E. Fair <fair@apple.com>, November 12, 1989
+**
+** ANSIfy the code somewhat to make gcc -Wall happy with the code.
+** Submit to NetBSD

+.Dt SLEEP 1
+.Os
+.Sh NAME
+.Nm sleep
+.Nd suspend execution for an interval of time
+.Sh SYNOPSIS
+.Nm
+.Ar seconds
+.Sh DESCRIPTION
+The
+.Nm
+utility
+suspends execution for a minimum of
+.Ar seconds .
+It is usually used to schedule the execution of other commands (see
+.Sx EXAMPLES
+below).
+.Pp
+The
+.Nm
+utility exits with one of the following values:
+.Bl -tag -width flag
+.It Li \&0
+On successful completion, or if the signal
+.Dv SIGALRM
+was received.
+.It Li \&>\&0
+An error occurred.
+.El
+.Pp
+Note: The
+.Nx
+.Nm
+command will accept and honor a non-integer number of specified
+seconds. This is a non-portable extension, and its use will nearly
+guarantee that a shell script will not execute properly on another
+system.
+.Sh EXAMPLES
+To schedule the execution of a command for
+.Va x
+number seconds later:
+.Pp
+.Dl (sleep 1800; sh command_file >& errors)&
+.Pp
+This incantation would wait a half hour before
+running the script command_file. (See the
+.Xr at 1
+utility.)
+.Pp
+To reiteratively run a command (with the
+.Xr csh 1 ) :
+.Pp
+.Bd -literal -offset indent -compact
+while (1)
+ if (! -r zzz.rawdata) then
+ sleep 300
+ else
+ foreach i (`ls *.rawdata`)
+ sleep 70
+ awk -f collapse_data $i >> results
+ end
+ break
+ endif
+end
+.Ed
+.Pp
+The scenario for a script such as this might be: a program currently
+running is taking longer than expected to process a series of
+files, and it would be nice to have
+another program start processing the files created by the first
+program as soon as it is finished (when zzz.rawdata is created).
+The script checks every five minutes for the file zzz.rawdata,
+when the file is found, then another portion processing
+is done courteously by sleeping for 70 seconds in between each
+awk job.
+.Sh SEE ALSO
+.Xr nanosleep 2 ,
+.Xr sleep 3 ,
+.Xr at 1
+.Sh STANDARDS
+The
+.Nm
+command is expected to be
+.St -p1003.2
+compatible.

+.Sh SYNOPSIS
+.Nm
+.Op Fl Kflm
+.Op Ar login Op Ar "shell arguments"
+.Sh DESCRIPTION
+.Nm
+requests the Kerberos password for
+.Ar login
+(or for
+.Dq Ar login Ns .root ,
+if no login is provided), and switches to
+that user and group ID after obtaining a Kerberos ticket granting ticket.
+A shell is then executed, and any additional
+.Ar "shell arguments"
+after the login name
+are passed to the shell.
+.Nm
+will resort to the local password file to find the password for
+.Ar login
+if there is a Kerberos error.
+If
+.Nm
+is executed by root, no password is requested and a shell
+with the appropriate user ID is executed; no additional Kerberos tickets
+are obtained.
+.Pp
+Alternatively, if the user enters the password "s/key", authentication
+will use the S/Key one-time password system as described in
+.Xr skey 1 .
+S/Key is a Trademark of Bellcore.
+.Pp
+By default, the environment is unmodified with the exception of
+.Ev USER ,
+.Ev HOME ,
+and
+.Ev SHELL .
+.Ev HOME
+and
+.Ev SHELL
+are set to the target login's default values.

+.Sh NAME
+.Nm test ,
+.Nm [
+.Nd condition evaluation utility
+.Sh SYNOPSIS
+.Nm test
+.Ar expression
+.Nm [
+.Ar expression Cm ]
+.Sh DESCRIPTION
+The
+.Nm test
+utility evaluates the expression and, if it evaluates
+to true, returns a zero (true) exit status; otherwise
+it returns 1 (false).
+If there is no expression, test also
+returns 1 (false).
+.Pp
+All operators and flags are separate arguments to the
+.Nm test
+utility.
+.Pp
+The following primaries are used to construct expression:
+.Bl -tag -width Ar
+.It Fl b Ar file
+True if
+.Ar file
+exists and is a block special
+file.
+.It Fl c Ar file
+True if
+.Ar file
+exists and is a character
+special file.
+.It Fl d Ar file
+True if
+.Ar file
+exists and is a directory.
+.It Fl e Ar file
+True if
+.Ar file
+exists (regardless of type).
+.It Fl f Ar file
+True if
+.Ar file
+exists and is a regular file.
+.It Fl g Ar file
+True if
+.Ar file
+exists and its set group ID flag
+is set.
+.It Fl h Ar file
+True if
+.Ar file
+exists and is a symbolic link.
+This operator is retained for compatibility with previous versions of
+this program. Do not rely on its existence; use
+.Fl L
+instead.
+.It Fl k Ar file
+True if
+.Ar file
+exists and its sticky bit is set.
+.It Fl n Ar string
+True if the length of
+.Ar string
+is nonzero.
+.It Fl p Ar file
+True if
+.Ar file
+is a named pipe
+.Po Tn FIFO Pc .
+.It Fl r Ar file
+True if
+.Ar file
+exists and is readable.
+.It Fl s Ar file
+True if
+.Ar file
+exists and has a size greater
+than zero.
+.It Fl t Ar file_descriptor
+True if the file whose file descriptor number
+is
+.Ar file_descriptor
+is open and is associated with a terminal.
+.It Fl u Ar file
+True if
+.Ar file
+exists and its set user ID flag
+is set.
+.It Fl w Ar file
+True if
+.Ar file
+exists and is writable.
+True
+indicates only that the write flag is on.
+The file is not writable on a read-only file
+system even if this test indicates true.
+.It Fl x Ar file
+True if
+.Ar file
+exists and is executable.
+True
+indicates only that the execute flag is on.
+If
+.Ar file
+is a directory, true indicates that
+.Ar file
+can be searched.
+.It Fl z Ar string
+True if the length of
+.Ar string
+is zero.
+.It Fl L Ar file
+True if
+.Ar file
+exists and is a symbolic link.
+.It Fl O Ar file
+True if
+.Ar file
+exists and its owner matches the effective user id of this process.
+.It Fl G Ar file
+True if
+.Ar file
+exists and its group matches the effective group id of this process.
+.It Fl S Ar file
+True if
+.Ar file
+exists and is a socket.
+.It Ar file1 Fl nt Ar file2
+True if
+.Ar file1
+exists and is newer than
+.Ar file2 .
+.It Ar file1 Fl ot Ar file2
+True if
+.Ar file1
+exists and is older than
+.Ar file2 .
+.It Ar file1 Fl ef Ar file2
+True if
+.Ar file1
+and
+.Ar file2
+exist and refer to the same file.
+.It Ar string
+True if
+.Ar string
+is not the null
+string.
+.It Ar \&s\&1 Cm \&= Ar \&s\&2
+True if the strings
+.Ar \&s\&1
+and
+.Ar \&s\&2
+are identical.
+.It Ar \&s\&1 Cm \&!= Ar \&s\&2
+True if the strings
+.Ar \&s\&1
+and
+.Ar \&s\&2
+are not identical.
+.It Ar \&s\&1 Cm \&< Ar \&s\&2
+True if string
+.Ar \&s\&1
+comes before
+.Ar \&s\&2
+based on the ASCII value of their characters.
+.It Ar \&s\&1 Cm \&> Ar \&s\&2
+True if string
+.Ar \&s\&1
+comes after
+.Ar \&s\&2
+based on the ASCII value of their characters.
+.It Ar \&s\&1
+True if
+.Ar \&s\&1
+is not the null
+string.
+.It Ar \&n\&1 Fl \&eq Ar \&n\&2
+True if the integers
+.Ar \&n\&1
+and
+.Ar \&n\&2
+are algebraically
+equal.
+.It Ar \&n\&1 Fl \&ne Ar \&n\&2
+True if the integers
+.Ar \&n\&1
+and
+.Ar \&n\&2
+are not
+algebraically equal.
+.It Ar \&n\&1 Fl \> Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically
+greater than the integer
+.Ar \&n\&2 .
+.It Ar \&n\&1 Fl \&ge Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically
+greater than or equal to the integer
+.Ar \&n\&2 .
+.It Ar \&n\&1 Fl \< Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically less
+than the integer
+.Ar \&n\&2 .
+.It Ar \&n\&1 Fl \&le Ar \&n\&2
+True if the integer
+.Ar \&n\&1
+is algebraically less
+than or equal to the integer
+.Ar \&n\&2 .
+.El
+.Pp
+These primaries can be combined with the following operators:
+.Bl -tag -width Ar
+.It Cm \&! Ar expression
+True if
+.Ar expression
+is false.
+.It Ar expression1 Fl a Ar expression2
+True if both
+.Ar expression1
+and
+.Ar expression2
+are true.
+.It Ar expression1 Fl o Ar expression2
+True if either
+.Ar expression1
+or
+.Ar expression2
+are true.
+.It Cm \&( Ns Ar expression Ns Cm \&)
+True if expression is true.
+.El
+.Pp
+The
+.Fl a
+operator has higher precedence than the
+.Fl o
+operator.
+.Sh GRAMMAR AMBIGUITY
+The
+.Nm test
+grammar is inherently ambiguous. In order to assure a degree of consistency,
+the cases described in
+.St -p1003.2
+section 4.62.4,
+are evaluated consistently according to the rules specified in the
+standards document. All other cases are subject to the ambiguity in the
+command semantics.
+.Sh RETURN VALUES
+The
+.Nm test
+utility exits with one of the following values:
+.Bl -tag -width Ds
+.It 0
+expression evaluated to true.
+.It 1
+expression evaluated to false or expression was
+missing.
+.It >1
+An error occurred.
+.El
+.Sh STANDARDS
+The
+.Nm test
+utility implements a superset of the
+.St -p1003.2
+specification.

+.Sh NAME
+.Nm time
+.Nd time command execution
+.Sh SYNOPSIS
+.Nm
+.Op Fl lp
+.Ar utility
+.Sh DESCRIPTION
+The
+.Nm
+utility
+executes and
+times
+.Ar utility .
+After the
+.Ar utility
+finishes,
+.Nm
+writes the total time elapsed,
+the time consumed by system overhead,
+and the time used to execute
+.Ar utility
+to the standard error stream.
+Times are reported in seconds.
+.Pp
+Available options:
+.Bl -tag -width Ds
+.It Fl l
+The contents of the
+.Em rusage
+structure are printed.
+.It Fl p
+The output is formatted as specified by
+.St -p1003.2-92 .
+.El
+.Pp
+The
+.Xr csh 1
+has its own and syntactically different builtin version of
+.Nm "" .
+The utility described here
+is available as
+.Pa /usr/bin/time
+to
+.Xr csh
+users.
+.Sh DIAGNOSTICS
+The
+.Nm
+utility shall exit with one of the following values:
+.Bl -tag -width indent
+.It 1-125
+An error occurred in the
+.Nm
+utility.
+.It 126
+The
+.Ar utility
+was found but could not be invoked.
+.It 127
+The
+.Ar utility
+could not be found.
+.El
+.Pp
+Otherwise, the exit status of
+.Nm
+shall be that of
+.Ar utility .
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr getrusage 2
+.Sh FILES
+.Bl -tag -width /usr/include/sys/resource.h -compact
+.It Pa /usr/include/sys/resource.h
+.El
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.2-92 .
+.Sh BUGS
+The granularity of seconds on microprocessors is crude and
+can result in times being reported for CPU usage which are too large by
+a second.

+.Sh SYNOPSIS
+.Nm
+.Op Fl hin
+.Op Fl M Ar core
+.Op Fl N Ar system
+.Op Ar user
+.Sh DESCRIPTION
+The
+.Nm
+utility prints a summary of the current activity on the system,
+including what each user is doing.
+The first line displays the current time of day, how long the system has
+been running, the number of users logged into the system, and the load
+averages.
+The load average numbers give the number of jobs in the run queue averaged
+over 1, 5 and 15 minutes.
+.Pp
+The fields output are the user's login name, the name of the terminal the
+user is on, the host from which the user is logged in, the time the user
+logged on, the time since the user last typed anything,
+and the name and arguments of the current process.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl h
+Suppress the heading.
+.It Fl i
+Output is sorted by idle time.
+.It Fl M
+Extract values associated with the name list from the specified
+core instead of the default
+.Dq /dev/kmem .
+.It Fl N
+Extract the name list from the specified system instead of the
+default
+.Dq /netbsd .
+.It Fl n
+Show network addresses as numbers (normally
+.Nm
+interprets addresses and attempts to display them symbolically).
+.El
+.Pp
+If a
+.Ar user
+name is specified, the output is restricted to that user.
+.Sh FILES

+.Xr uptime 1
+.Sh BUGS
+The notion of the
+.Dq current process
+is muddy.
+The current algorithm is ``the highest numbered process on the terminal
+that is not ignoring interrupts, or, if there is none, the highest numbered
+process on the terminal''.
+This fails, for example, in critical sections of programs like the shell
+and editor, or when faulty programs running in the background fork and fail
+to ignore interrupts.
+(In cases where no process can be found,
+.Nm
+prints
+.Dq \- . )
+.Pp
+The
+.Tn CPU
+time is only an estimate, in particular, if someone leaves a background
+process running after logging out, the person currently on that terminal is
+.Dq charged
+with the time.
+.Pp
+Background processes are not shown, even though they account for
+much of the load on the system.
+.Pp
+Sometimes processes, typically those in the background, are printed with
+null or garbaged arguments.
+In these cases, the name of the command is printed in parentheses.
+.Pp
+The
+.Nm
+utility does not know about the new conventions for detection of background
+jobs.
+It will sometimes find a background job instead of the right one.
+.Sh COMPATIBILITY
+The
+.Fl f ,
+.Fl l ,
+.Fl s ,
+and
+.Fl w
+flags are no longer supported.

+each user the login name, tty name, the date and time of login, and
+hostname if not local.
+.Pp
+Available options:
+.Pp
+.Bl -tag -width file

+Only print information about the current terminal. This is the
+.Tn POSIX
+way of saying
+.Nm
+.Ar am i .
+.It Fl T
+Print a character after the user name indicating the state of the
+terminal line:
+.Sq +
+if the terminal is writable;
+.Sq -
+if it is not;
+and
+.Sq ?
+if a bad line is encountered.
+.It Fl u
+Print the idle time for each user.
+.It Fl H
+Write column headings above the regular output.
+.It Ar \&am I
+Returns the invoker's real user name.
+.It Ar file
+By default,
+.Nm
+gathers information from the file
+.Pa /var/run/utmp .
+An alternative
+.Ar file
+may be specified which is usually
+.Pa /var/log/wtmp
+(or
+.Pa /var/log/wtmp.[0-6]
+depending on site policy as
+.Pa wtmp
+can grow quite large and daily versions may or may not
+be kept around after compression by
+.Xr ac 8 ) .
+The
+.Pa wtmp
+file contains a record of every login, logout,
+crash, shutdown and date change
+since
+.Pa wtmp
+was last truncated or
+created.
+.El
+.Pp
+If
+.Pa /var/log/wtmp
+is being used as the file, the user name may be empty
+or one of the special characters '|', '}' and '~'. Logouts produce
+an output line without any user name. For more information on the
+special characters, see
+.Xr utmp 5 .

+Compilation notes:
+
+ Compiler options:
+
+ BYTE_ORDER (used only in ww.h)
+ It should already be defined in machine/endian.h.
+ The code knows about BIG_ENDIAN, LITTLE_ENDIAN, and PDP_ENDIAN.
+ It only cares about byte order in words, so PDP_ENDIAN
+ is the same as LITTLE_ENDIAN.
+ OLD_TTY
+ If you don't have Posix termios, then define this.
+ VMIN_BUG
+ Even if you have Posix termios, define this if the MIN and TIME
+ feature in noncanonical mode doesn't work correctly.
+
+ Ok, there's another one, STR_DEBUG. It turns on consistency checks
+ in the string allocator. It's been left on since performace doesn't
+ seem to suffer. There's an abort() somewhere when an inconsistency
+ is found. It hasn't happened in years.
+
+ The file local.h contains locally tunable constants.
+
+ The makefile used to be updated with mkmf; it has been changed
+at various times to use cpp -M and, currently, mkdep. The only library
+it needs is termcap.
+
+ Window, as is, only runs on 4.3 (or later) machines.
+
+ On 4.2 machines, at least these modifications must be done:
+
+ delete uses of window size ioctls: TIOCGWINSZ, TIOCSWINSZ,
+ struct winsize
+ add to ww.h
+ typedef int fd_set;
+ #define FD_ZERO(s) (*(s) = 0)
+ #define FD_SET(b, s) (*(s) |= 1 << (b))
+ #define FD_ISSET(b, s) (*(s) & 1 << (b))
+ add to ww.h
+ #define sigmask(s) (1 << (s) - 1)
+
+
+A few notes about the internals:
+
+ The window package. Windows are opened by calling wwopen().
+Wwwrite() is the primitive for writing to windows. Wwputc(), wwputs(),
+and wwprintf() are also supported. Some of the outputs to windows are
+delayed. Wwupdate() updates the terminal to match the internal screen
+buffer. Wwspawn() spawns a child process on the other end of a window,
+with its environment tailored to the window. Visible windows are
+doubly linked in the order of their overlap. Wwadd() inserts a window
+into the list at a given place. Wwdelete() deletes it. Windows not in
+the list are not visible, though wwwrite() still works. Window was
+written before the days of X and Sunview, so some of the terminology
+is not standard.
+
+ Most functions return -1 on error. Wwopen() returns the null
+pointer. An error number is saved in wwerrno. Wwerror() returns an
+error string based on wwerrno suitable for printing.
+
+ The terminal drivers perform all output to the physical terminal,
+including special functions like character and line insertion and
+deletion. The window package keeps a list of known terminals. At
+initialization time, the terminal type is matched against the list to
+find the right terminal driver to use. The last driver, the generic
+driver, matches all terminals and uses the termcap database. The
+interface between the window package the terminal driver is the `tt'
+structure. It contains pointers to functions to perform special
+functions and terminal output, as well as flags about the
+characteristics of the terminal. Most of these ideas are borrowed
+from the Maryland window package, which in turn is based on Goslin's
+Emacs.
+
+ The IO system is semi-synchronous. Terminal input is signal
+driven, and everything else is done synchronously with a single
+select(). It is roughly event-driven, though not in a clean way.
+
+ Normally, in both conversation mode and command mode, window
+sleeps in a select() in wwiomux() waiting for data from the
+pseudo-terminals. At the same time, terminal input causes SIGIO which
+is caught by wwrint(). The select() returns when at least one of the
+pseudo-terminals becomes ready for reading.
+
+ Wwrint() is the interrupt handler for tty input. It reads input
+into a linear buffer accessed through four pointers:
+
+ +-------+--------------+----------------+
+ | empty | data | empty |
+ +-------+--------------+----------------+
+ ^ ^ ^ ^
+ | | | |
+ wwib wwibp wwibq wwibe
+
+Wwrint() appends characters at the end and increments wwibq (*wwibq++
+= c), and characters are taken off the buffer at wwibp using the
+wwgetc() and wwpeekc() macros. As is the convention in C, wwibq
+and wwibe point to one position beyond the end. In addition,
+wwrint() will do a longjmp(wwjmpbuf) if wwsetjmp is true. This is
+used by wwiomux() to interrupt the select() which would otherwise
+resume after the interrupt. (Actually, I hear this is not true,
+but the longjmp feature is used to avoid a race condition as well.
+Anyway, it means I didn't have to depend on a feature in a
+daily-changing kernel, but that's another story.) The macro
+wwinterrupt() returns true if the input buffer is non-empty.
+Wwupdate(), wwwrite(), and wwiomux() check this condition and will
+return at the first convenient opportunity when it becomes true.
+In the case of wwwrite(), the flag ww_nointr in the window structure
+overrides this. This feature allows the user to interrupt lengthy
+outputs safely. The structure of the input buffer is designed to
+avoid race conditions without blocking interrupts.
+
+ Actually, wwsetjmp and wwinterrupt() are part of a software
+interrupt scheme used by the two interrupt catchers wwrint() and
+wwchild(). Asserting the interrupt lets the synchronous parts of
+the program know that there's an interesting asynchronous condition
+(i.e., got a keyboard character, or a child process died) that they
+might want to process before anything else. The synchronous routines
+can check for this condition with wwinterrupt() or by arranging
+that a longjmp() be done.
+
+ Wwiomux() copies pseudo-terminal output into their corresponding
+windows. Without anything to do, it blocks in a select(), waiting for
+read ready on pseudo-terminals. Reads are done into per-window buffers
+in the window structures. When there is at least one buffer non-empty,
+wwiomux() finds the top most of these windows and writes it using
+wwwrite(). Then the process is repeated. A non-blocking select() is
+done after a wwwrite() to pick up any output that may have come in
+during the write, which may take a long time. Specifically, we use
+this to stop output or flush buffer when a pseudo-terminal tells us to
+(we use pty packet mode). The select() blocks only when all of the
+windows' buffers are empty. A wwupdate() is done prior to this, which
+is the only time the screen is guaranteed to be completely up to date.
+Wwiomux() loops until wwinterrupt() becomes true.
+
+ The top level routine for all this is mloop(). In conversation
+mode, it simply calls wwiomux(), which only returns when input is
+available. The input buffer is then written to the pseudo-terminal of
+the current window. If the escape character is found in the input,
+command mode is entered. Otherwise, the process is repeated. In
+command mode, control is transferred to docmd() which returns only when
+conversation mode is reentered. Docmd() and other command processing
+routines typically wait for input in a loop:
+
+ while (wwpeekc() < 0)
+ wwiomux();
+
+When the loop terminates, wwgetc() is used to read the input buffer.
+
+ Output to the physical terminal is handled by the lowest level
+routines of the window package, in the files ttoutput.c and tt.h. The
+standard IO package is not used, to get better control over buffering
+and to use non-blocking reads in wwrint(). The buffer size is set to
+approximately one second of output time, based on the baudrate.
+
+ The result of all this complexity is faster response time,
+especially in output stopping and flushing. Wwwrite() checks
+wwinterrupt() after every line. It also calls wwupdate() for each line
+it writes. The output buffer is limited to one second of output time.
+Thus, there is usually only a delay of one to two lines plus one second
+after a ^C or ^S. Also, commands that produce lengthy output can be
+aborted without actually showing all of it on the terminal. (Try the
+'?' command followed by escape immediately.)

+.Nm window
+.Nd window environment
+.Sh SYNOPSIS
+.Nm
+.Op Fl t
+.Op Fl f
+.Op Fl d
+.Op Fl e Ar escape-char
+.Op Fl c Ar command
+.Sh DESCRIPTION
+.Nm
+implements a window environment on
+.Tn ASCII
+terminals.
+.Pp
+A window is a rectangular portion of the physical terminal
+screen associated with a set of processes. Its size and
+position can be changed by the user at any time. Processes
+communicate with their window in the same way they normally
+interact with a terminal\-through their standard input, output,
+and diagnostic file descriptors. The window program handles the
+details of redirecting input and output to and from the
+windows. At any one time, only one window can receive
+input from the keyboard, but all windows can simultaneously send output
+to the display.
+.Pp
+When
+.Nm
+starts up, the commands (see long commands below)
+contained in the file
+.Pa .windowrc
+in the user's home directory are
+executed. If it does not exist, two equal sized windows spanning
+the terminal screen are created by default.
+.Pp
+The command line options are
+.Bl -tag -width Fl
+.It Fl t
+Turn on terse mode (see
+.Ic terse
+command below).
+.It Fl f
+Fast. Don't perform any startup action.
+.It Fl d
+Ignore
+.Pa .windowrc
+and create the two default
+windows instead.
+.It Fl e Ar escape-char
+Set the escape character to
+.Ar escape-char .
+.Ar Escape-char
+can be a single character, or in the form
+.Ic ^X
+where
+.Ar X
+is any character, meaning
+.No control\- Ns Ar X .
+.It Fl c Ar command
+Execute the string
+.Ar command
+as a long command (see below)
+before doing anything else.
+.El
+.Pp
+Windows can overlap and are framed as necessary. Each window
+is named by one of the digits ``1'' to ``9''. This one-character
+identifier, as well as a user definable label string, are displayed
+with the window on the top edge of its frame. A window can be
+designated to be in the
+.Ar foreground ,
+in which case it will always be
+on top of all normal, non-foreground windows, and can be covered
+only by other foreground windows. A window need not be completely
+within the edges of the terminal screen. Thus a large window
+(possibly larger than the screen) may be positioned to show only
+a portion of its full size.
+.Pp
+Each window has a cursor and a set of control functions. Most intelligent
+terminal operations such as line and
+character deletion and insertion are supported. Display modes
+such as underlining and reverse video are available if they are
+supported by the terminal. In addition,
+similar to terminals with multiple pages of memory,
+each window has a text buffer which can have more lines than the window
+itself.
+.Ss Process Environment
+With each newly created window, a shell program is spawned with its
+process environment tailored to that window. Its standard input,
+output, and diagnostic file descriptors are bound to one end of either
+a pseudo-terminal
+.Xr (pty 4 )
+or a
+.Ux
+domain socket
+.Xr (socketpair 4 ) .
+If a pseudo-terminal is used, then its special
+characters and modes (see
+.Xr stty 1 )
+are copied from the physical
+terminal. A
+.Xr termcap 5
+entry tailored to this window is created
+and passed as environment
+.Xr (environ 5 )
+variable
+.Ev TERMCAP .
+The termcap entry contains the window's size and
+characteristics as well as information from the physical terminal,
+such as the existence of underline, reverse video, and other display
+modes, and the codes produced by the terminal's function keys,
+if any. In addition, the window size attributes of the pseudo-terminal
+are set to reflect the size of this window, and updated whenever
+it is changed by the user. In particular, the editor
+.Xr vi 1
+uses
+this information to redraw its display.
+.Ss Operation
+During normal execution,
+.Nm
+can be in one of two states:
+conversation mode and command mode. In conversation mode, the
+terminal's real cursor is placed at the cursor position of a particular
+window--called the current window--and input from the keyboard is sent
+to the process in that window. The current window is always
+on top of all other windows, except those in foreground. In addition,
+it is set apart by highlighting its identifier and label in reverse video.
+.Pp
+Typing
+.Nm "" Ns 's
+escape character (normally
+.Ic ^P )
+in conversation
+mode switches it into command mode. In command mode, the top line of
+the terminal screen becomes the command prompt window, and
+.Nm
+interprets input from the keyboard as commands to manipulate windows.
+.Pp
+There are two types of commands: short commands are usually one or two
+key strokes; long commands are strings either typed by the user in the
+command window (see the
+.Dq Ic \&:
+command below), or read from a file (see
+.Ic source
+below).
+.Ss Short Commands
+Below,
+.Ar \&#
+represents one of the digits ``1'' to ``9''
+corresponding to the windows 1 to 9.
+.Ic ^X
+means
+.No control\- Ns Ar X ,
+where
+.Ar X
+is any character. In particular,
+.Ic ^^
+is
+.Li control\-^.
+.Ar Escape
+is the escape key, or
+.Ic ^\&[ .
+.Bl -tag -width Ds
+.It Ar #
+Select window
+.Ar #
+as the current window
+and return to conversation mode.
+.It Ic \&% Ns Ar #
+Select window
+.Ar #
+but stay in command mode.
+.It Ic ^^
+Select the previous window and return to conversation
+mode. This is useful for toggling between two windows.
+.It Ic escape
+Return to conversation mode.
+.It Ic ^P
+Return to conversation mode and write
+.Ic ^P
+to the
+current window. Thus, typing two
+.Ic ^P Ns 's
+in conversation
+mode sends one to the current window. If the
+.Nm
+escape is changed to some other character, that
+character takes the place of
+.Ic ^P
+here.
+.It Ic ?
+List a short summary of commands.
+.It Ic ^L
+Refresh the screen.
+.It Ic q
+Exit
+.Nm "" .
+Confirmation is requested.
+.It Ic ^Z
+Suspend
+.Nm "" .
+.It Ic w
+Create a new window. The user is prompted for the positions
+of the upper left and lower right corners of the window.
+The cursor is placed on the screen and the keys ``h'', ``j'',
+``k'', and ``l''
+move the cursor left, down, up, and right, respectively.
+The keys ``H'', ``J'', ``K'', and ``L'' move the cursor to the respective
+limits of the screen. Typing a number before the movement keys
+repeats the movement that number of times. Return enters the cursor position
+as the upper left corner of the window. The lower right corner
+is entered in the same manner. During this process,
+the placement of the new window is indicated by a rectangular
+box drawn on the screen, corresponding to where the new window
+will be framed. Typing escape at any point
+cancels this command.
+.Pp
+This window becomes the current window,
+and is given the first available ID. The default buffer size
+is used (see
+.Ar default_nline
+command below).
+.Pp
+Only fully visible windows can be created this way.
+.It Ic c Ns Ar #
+Close window
+.Ar # .
+The process in the window is sent
+the hangup signal (see
+.Xr kill 1 ) .
+.Xr Csh 1
+should
+handle this signal correctly and cause no problems.
+.It Ic m Ns Ar #
+Move window
+.Ar #
+to another location. A box in the shape
+of the window is drawn on
+the screen to indicate the new position of the window, and the same keys as
+those for the
+.Ic w
+command are used to position the box. The
+window can be moved partially off-screen.
+.It Ic M Ns Ar #
+Move window
+.Ar #
+to its previous position.
+.It Ic s Ns Ar #
+Change the size of window
+.Ar # .
+The user is prompted
+to enter the new lower right corner of the window. A box
+is drawn to indicate the new window size. The same
+keys used in
+.Ic w
+and
+.Ic m
+are used to enter the position.
+.It Ic S Ns Ar #
+Change window
+.Ar #
+to its previous size.
+.It Ic ^Y
+Scroll the current window up by one line.
+.It Ic ^E
+Scroll the current window down by one line.
+.It Ic ^U
+Scroll the current window up by half the window size.
+.It Ic ^D
+Scroll the current window down by half the window size.
+.It Ic ^B
+Scroll the current window up by the full window size.
+.It Ic ^F
+Scroll the current window down by the full window size.
+.It Ic h
+Move the cursor of the current window left by one column.
+.It Ic j
+Move the cursor of the current window down by one line.
+.It Ic k
+Move the cursor of the current window up by one line.
+.It Ic l
+Move the cursor of the current window right by one column.
+.It Ic y
+Yank. The user is prompted to enter two points within the current
+window. Then the content of the current window between those two points
+is saved in the yank buffer.
+.It Ic p
+Put. The content of the yank buffer is written to the current
+window as input.
+.It Ic ^S
+Stop output in the current window.
+.It Ic ^Q
+Start output in the current window.
+.It Ic :
+Enter a line to be executed as long commands.
+Normal line
+editing characters (erase character, erase word, erase line)
+are supported.
+.El
+.Ss Long Commands
+Long commands are a sequence of statements
+parsed much like a programming language, with a syntax
+similar to that of C. Numeric and string expressions and variables
+are supported, as well as conditional statements.
+.Pp
+There are two data types: string and number. A string is a sequence
+of letters or digits beginning with a letter. ``_'' and ``.'' are
+considered letters. Alternatively, non-alphanumeric characters can
+be included in strings by quoting them in ``"'' or escaping them
+with ``\\''. In addition, the ``\\'' sequences of C are supported,
+both inside and outside quotes (e.g., ``\\n'' is a new line,
+``\\r'' a carriage return). For example, these are legal strings:
+abcde01234, "&#$^*&#", ab"$#"cd, ab\\$\\#cd, "/usr/ucb/window".
+.Pp
+A number is an integer value in one of three forms:
+a decimal number, an octal number preceded by ``0'',
+or a hexadecimal number preceded by ``0x'' or ``0X''. The natural
+machine integer size is used (i.e., the signed integer type
+of the C compiler). As in C, a non-zero number represents
+a boolean true.
+.Pp
+The character ``#'' begins a comment which terminates at the
+end of the line.
+.Pp
+A statement is either a conditional or an expression. Expression
+statements are terminated with a new line or ``;''. To continue
+an expression on the next line, terminate the first line with ``\\''.
+.Ss Conditional Statement
+.Nm
+has a single control structure:
+the fully bracketed if statement in the form
+.Pp
+.Bd -literal -offset indent -compact
+if <expr> then
+\t<statement>
+\t...
+elsif <expr> then
+\t<statement>
+\t...
+else
+\t<statement>
+\t...
+endif
+.Ed
+.Pp
+The
+.Ic else
+and
+.Ic elsif
+parts are optional, and the latter can
+be repeated any number of times.
+<Expr>
+must be numeric.
+.Ss Expressions
+Expressions in
+.Nm
+are similar to those in the
+C language, with most C operators supported on numeric
+operands. In addition, some are overloaded to operate on strings.
+.Pp
+When an expression is used as a statement, its value is discarded
+after evaluation. Therefore, only expressions with side
+effects (assignments and function calls) are useful as statements.
+.Pp
+Single valued (no arrays) variables are supported, of both
+numeric and string values. Some variables are predefined. They
+are listed below.
+.Pp
+The operators in order of increasing precedence:
+.Bl -tag -width Fl
+.It Xo
+.Aq Va expr1
+.Ic =
+.Aq Va expr2
+.Xc
+Assignment. The variable of name
+.Aq Va expr1 ,
+which must be string valued,
+is assigned the result of
+.Aq Va expr2 .
+Returns the value of
+.Aq Va expr2 .
+.It Xo
+.Aq Va expr1
+.Ic ?
+.Aq Va expr2
+.Ic :
+.Aq Va expr3
+.Xc
+Returns the value of
+.Aq Va expr2
+if
+.Aq Va expr1
+evaluates true
+(non-zero numeric value); returns the value of
+.Aq Va expr3
+otherwise. Only
+one of
+.Aq Va expr2
+and
+.Aq Va expr3
+is evaluated.
+.Aq Va Expr1
+must
+be numeric.
+.It Xo
+.Aq Va expr1
+.Ic \&|\&|
+.Aq Va expr2
+.Xc
+Logical or. Numeric values only. Short circuit evaluation is supported
+(i.e., if
+.Aq Va expr1
+evaluates true, then
+.Aq Va expr2
+is not evaluated).
+.It Xo

+.Ic \&&\&&
+.Aq Va expr2
+.Xc
+Logical and with short circuit evaluation. Numeric values only.
+.It Xo

+Bitwise exclusive or. Numeric values only.
+.It Xo

+.Ic \&&
+.Aq Va expr2
+.Xc
+Bitwise and. Numeric values only.
+.It Xo
+.Aq Va expr1
+.Ic ==
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic !=
+.Aq expr2
+.Xc
+Comparison (equal and not equal, respectively). The boolean
+result (either 1 or 0) of the comparison is returned. The
+operands can be numeric or string valued. One string operand
+forces the other to be converted to a string in necessary.
+.It Xo
+.Aq Va expr1
+.Ic <
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic >
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic <=
+.Aq Va expr2 ,

+Less than, greater than, less than or equal to,
+greater than or equal to. Both numeric and string values, with
+automatic conversion as above.
+.It Xo
+.Aq Va expr1
+.Ic <<
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic >>
+.Aq Va expr2
+.Xc
+If both operands are numbers,
+.Aq Va expr1
+is bit
+shifted left (or right) by
+.Aq Va expr2
+bits. If
+.Aq Va expr1
+is
+a string, then its first (or last)
+.Aq Va expr2
+characters are
+returns (if
+.Aq Va expr2
+is also a string, then its length is used
+in place of its value).
+.It Xo
+.Aq Va expr1
+.Ic +
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic -
+.Aq Va expr2
+.Xc
+Addition and subtraction on numbers. For ``+'', if one
+argument is a string, then the other is converted to a string,
+and the result is the concatenation of the two strings.
+.It Xo
+.Aq Va expr1
+.Ic \&*
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic \&/
+.Aq Va expr2 ,
+.Aq Va expr1
+.Ic \&%
+.Aq Va expr2

+Multiplication, division, modulo. Numbers only.
+.It Xo
+.Ic \- Ns Aq Va expr ,
+.Ic ~ Ns Aq Va expr ,
+.Ic \&! Ns Aq Va expr ,
+.Ic \&$ Ns Aq Va expr ,
+.Ic \&$? Ns Aq Va expr
+.Xc
+The first three are unary minus, bitwise complement and logical complement
+on numbers only. The operator, ``$'', takes
+.Aq Va expr
+and returns
+the value of the variable of that name. If
+.Aq Va expr
+is numeric
+with value
+.Ar n
+and it appears within an alias macro (see below),
+then it refers to the nth argument of the alias invocation. ``$?''
+tests for the existence of the variable
+.Aq Va expr ,
+and returns 1
+if it exists or 0 otherwise.
+.It Xo
+.Ao Va expr Ac Ns Pq Aq Ar arglist
+.Xc
+Function call.
+.Aq Va Expr
+must be a string that is the unique
+prefix of the name of a builtin
+.Nm
+function
+or the full name of a user defined alias macro. In the case of a builtin
+function,
+.Aq Ar arglist
+can be in one of two forms:
+.Bd -literal -offset indent
+<expr1>, <expr2>, ...
+argname1 = <expr1>, argname2 = <expr2>, ...
+.Ed
+.Pp
+The two forms can in fact be intermixed, but the result is
+unpredictable. Most arguments can be omitted; default values will
+be supplied for them. The
+.Ar argnames
+can be unique prefixes
+of the argument names. The commas separating
+arguments are used only to disambiguate, and can usually be omitted.
+.Pp
+Only the first argument form is valid for user defined aliases. Aliases
+are defined using the
+.Ic alias
+builtin function (see below). Arguments
+are accessed via a variant of the variable mechanism (see ``$'' operator
+above).
+.Pp
+Most functions return value, but some are used for side effect
+only and so must be used as statements. When a function or an alias is used
+as a statement, the parentheses surrounding
+the argument list may be omitted. Aliases return no value.
+.El
+.Ss Builtin Functions
+The arguments are listed by name in their natural
+order. Optional arguments are in square brackets
+.Sq Op .
+Arguments
+that have no names are in angle brackets
+.Sq <> .
+An argument meant to be a boolean flag (often named
+.Ar flag )
+can be one of
+.Ar on ,
+.Ar off ,
+.Ar yes ,
+.Ar no ,
+.Ar true ,
+or
+.Ar false ,
+with
+obvious meanings, or it can be a numeric expression,
+in which case a non-zero value is true.
+.Bl -tag -width Fl
+.It Xo

+If no argument is given, all currently defined alias macros are
+listed. Otherwise,
+.Aq Ar string
+is defined as an alias,

+.Aq Ar string\-list > .
+The previous definition of
+.Aq Ar string ,
+if any, is returned. Default for
+.Aq Ar string\-list
+is no change.
+.It Ic close Ns Pq Aq Ar window\-list
+Close the windows specified in

+.Ar m_ul
+(underline),
+.Ar m_rev
+(reverse video),
+.Ar m_blk
+(blinking),
+and
+.Ar m_grp

+sets the window cursors to blinking
+reverse video.
+.It Ic default_nline Ns Pq Bq Ar nline
+Set the default buffer size to

+considerably.
+.It Ic default_shell Ns Pq Bq Aq Ar string\-list
+Set the default window shell program to
+.Aq Ar string\-list .
+Returns

+.Ev SHELL .
+.It Ic default_smooth Ns Pq Bq Ar flag
+Set the default value of the

+is a boolean flag (one of
+.Ar on ,
+.Ar off ,
+.Ar yes ,
+.Ar no ,
+.Ar true ,
+.Ar false ,
+or a number,
+as described above). Default is no change.
+The old value (as a number) is returned.

+is the current window.
+.It Ic escape Ns Pq Bq Ar escapec
+Set the escape character to
+.Ar escape-char .
+Returns the old
+escape character as a one-character string. Default is no
+change.
+.Ar Escapec

+meaning
+.No control\- Ns Ar X .
+.It Xo
+.Ic foreground Ns ( Bq Ar window ,
+.Bq Ar flag )
+.Xc
+Move
+.Nm
+in or out of foreground.
+.Ar Flag
+is a boolean value. The old foreground flag
+is returned. Default for
+.Nm
+is the current window,
+default for
+.Ar flag
+is no change.
+.It Xo
+.Ic label Ns ( Bq Ar window ,
+.Bq Ar label )
+.Xc
+Set the label of
+.Nm
+to
+.Ar label .
+Returns the old
+label as a string. Default for
+.Nm
+is the current
+window, default for
+.Ar label
+is no change. To turn
+off a label, set it to an empty string ("").
+.It Ic list Ns Pq
+No arguments. List the identifiers and labels of all windows. No
+value is returned.
+.It Ic select Ns Pq Bq Ar window
+Make
+.Nm
+the current window. The previous current window
+is returned. Default is no change.
+.It Ic source Ns Pq Ar filename
+Read and execute the long commands in
+.Ar filename .
+Returns \-1 if the file cannot be read, 0 otherwise.
+.It Ic terse Ns Pq Bq flag
+Set terse mode to
+.Ar flag .
+In terse mode, the command window
+stays hidden even in command mode, and errors are reported by
+sounding the terminal's bell.
+.Ar Flag
+can take on the same
+values as in
+.Ar foreground
+above. Returns the old terse flag.
+Default is no change.
+.It Ic unalias Ns Pq Ar alias
+Undefine
+.Ar alias .
+Returns -1 if
+.Ar alias
+does not exist,
+0 otherwise.
+.It Ic unset Ns Pq Ar variable
+Undefine
+.Ar variable .
+Returns -1 if
+.Ar variable
+does not exist,
+0 otherwise.
+.It Ic variables Ns Pq
+No arguments. List all variables. No value is returned.
+.It Xo
+.Ic window Ns ( Bq Ar row ,
+.Bq Ar column ,
+.Bq Ar nrow ,

+.Bq Ar nline ,
+.Bq Ar label ,
+.Bq Ar pty ,
+.Bq Ar frame ,
+.Bq Ar mapnl ,
+.Bq Ar keepopen ,
+.Bq Ar smooth ,
+.Bq Ar shell ) .
+.Xc
+Open a window with upper left corner at
+.Ar row ,
+.Ar column
+and size
+.Ar nrow ,
+.Ar ncol .
+If
+.Ar nline
+is specified,
+then that many lines are allocated for the text buffer. Otherwise,
+the default buffer size is used. Default values for
+.Ar row ,
+.Ar column ,
+.Ar nrow ,
+and
+.Ar ncol
+are, respectively,
+the upper, left-most, lower, or right-most extremes of the
+screen.
+.Ar Label
+is the label string.
+.Ar Frame ,
+.Ar pty ,
+and
+.Ar mapnl
+are flag values
+interpreted in the same way as the argument to
+.Ar foreground
+(see above);
+they mean, respectively, put a frame around this window (default true),
+allocate pseudo-terminal for this window rather than socketpair (default
+true), and map new line characters in this window to carriage return
+and line feed (default true if socketpair is used, false otherwise).
+Normally, a window is automatically closed when its process
+exits. Setting
+.Ar keepopen
+to true (default false) prevents this
+action. When
+.Ar smooth
+is true, the screen is updated more frequently
+(for this window) to produce a more terminal-like behavior.
+The default value of
+.Ar smooth
+is set by the
+.Ar default_smooth
+command (see above).
+.Ar Shell
+is a list of strings that will be used as the shell
+program to place in the window (default is the program specified
+by
+.Ar default_shell ,
+see above). The created window's identifier
+is returned as a number.
+.It Xo
+.Ic write Ns ( Bq Ar window ,
+.Bq Aq Ar string\-list )
+.Xc
+Send the list of strings,
+.Aq Ar string-list ,
+to
+.Nm "" ,
+separated
+by spaces but not terminated with a new line. The strings are actually
+given to the window as input. No value is returned. Default
+is the current window.
+.El
+.Ss Predefined Variables
+These variables are for information only. Redefining them does
+not affect the internal operation of
+.Nm "" .
+.Bl -tag -width modes
+.It Ar baud
+The baud rate as a number between 50 and 38400.
+.It Ar modes
+The display modes (reverse video, underline, blinking, graphics)
+supported by the physical terminal. The value of
+.Ar modes
+is the bitwise or of some of the one bit values,
+.Ar m_blk ,
+.Ar m_grp ,
+.Ar m_rev ,
+and
+.Ar m_ul
+(see below).
+These values are useful
+in setting the window cursors' modes (see
+.Ar cursormodes
+above).
+.It Ar m_blk
+The blinking mode bit.
+.It Ar m_grp
+The graphics mode bit (not very useful).
+.It Ar m_rev
+The reverse video mode bit.
+.It Ar m_ul
+The underline mode bit.
+.It Ar ncol
+The number of columns on the physical screen.
+.It Ar nrow
+The number of rows on the physical screen.
+.It Ar term
+The terminal type. The standard name, found in the second name
+field of the terminal's
+.Ev TERMCAP
+entry, is used.
+.Sh ENVIRONMENT
+.Nm
+utilizes these environment variables:
+.Ev HOME ,
+.Ev SHELL ,
+.Ev TERM ,

+ * We handle retain (da and db) by putting the burden on scrolling up,
+ * which is the less common operation. It must ensure that
+ * text is not pushed below the screen, so scrolling down doesn't
+ * have to worry about it.
+ *
+ * Try scrolling region (or scrolling the whole screen) first.
+ * Can we assume "sr" doesn't push text below the screen
+ * so we don't have to worry about retain below?
+ * What about scrolling down with a newline? It probably does
+ * push text above (with da). Scrolling up would then have
+ * to take care of that.
+ * It's easy to be fool proof, but that slows things down.
+ * The current solution is to disallow tt_scroll_up if da or db is true
+ * but cs (scrolling region) is not. Again, we sacrifice scrolling
+ * up in favor of scrolling down. The idea is having scrolling regions
+ * probably means we can scroll (even the whole screen) with impunity.

+.Sh NAME
+.Nm xargs
+.Nd "construct argument list(s) and execute utility"
+.Sh SYNOPSIS
+.Nm
+.Op Fl 0
+.Op Fl t
+.Oo Op Fl x
+.Fl n Ar number
+.Oc
+.Op Fl s Ar size
+.Op Ar utility Op Ar arguments ...
+.Sh DESCRIPTION
+The
+.Nm
+utility reads space, tab, newline and end-of-file delimited arguments
+from the standard input and executes the specified
+.Ar utility
+with them as
+arguments.
+.Pp
+The utility and any arguments specified on the command line are given
+to the
+.Ar utility
+upon each invocation, followed by some number of the arguments read
+from standard input.
+The
+.Ar utility
+is repeatedly executed until standard input is exhausted.
+.Pp
+Spaces, tabs and newlines may be embedded in arguments using single
+(``\ '\ '')
+or double (``"'') quotes or backslashes (``\e'').
+Single quotes escape all non-single quote characters, excluding newlines,
+up to the matching single quote.
+Double quotes escape all non-double quote characters, excluding newlines,
+up to the matching double quote.
+Any single character, including newlines, may be escaped by a backslash.
+.Pp
+The options are as follows:
+.Bl -tag -width Fl
+.It Fl 0
+Use NUL
+(``\e0'')
+instead of whitespace as the argument separator.
+This can be used in conjuction with the
+.Fl print0
+option of
+.Xr find 1 .
+.It Fl n Ar number
+Set the maximum number of arguments taken from standard input for each
+invocation of the utility.
+An invocation of
+.Ar utility
+will use less than
+.Ar number
+standard input arguments if the number of bytes accumulated (see the
+.Fl s
+option) exceeds the specified
+.Ar size
+or there are fewer than
+.Ar number
+arguments remaining for the last invocation of
+.Ar utility .
+The current default value for
+.Ar number
+is 5000.
+.It Fl s Ar size
+Set the maximum number of bytes for the command line length provided to
+.Ar utility .
+The sum of the length of the utility name and the arguments passed to
+.Ar utility
+(including
+.Dv NULL
+terminators) will be less than or equal to this number.
+The current default value for
+.Ar size
+is
+.Dv ARG_MAX
+- 2048.
+.It Fl t
+Echo the command to be executed to standard error immediately before it
+is executed.
+.It Fl x
+Force
+.Nm
+to terminate immediately if a command line containing
+.Ar number
+arguments will not fit in the specified (or default) command line length.
+.El
+.Pp
+If no
+.Ar utility
+is specified,
+.Xr echo 1
+is used.
+.Pp
+Undefined behavior may occur if
+.Ar utility
+reads from the standard input.
+.Pp
+The
+.Nm
+utility exits immediately (without processing any further input) if a
+command line cannot be assembled,
+.Ar utility
+cannot be invoked, an invocation of the utility is terminated by a signal
+or an invocation of the utility exits with a value of 255.
+.Sh DIAGNOSTICS
+.Nm
+exits with one of the following values:
+.Bl -tag -width Ds -compact
+.It 0
+All invocations of
+.Ar utility
+returned a zero exit status.
+.It 123
+One or more invocations of
+.Ar utility
+returned a nonzero exit status.
+.It 124
+The
+.Ar utility
+exited with a 255 exit status.
+.It 125
+The
+.Ar utility
+was killed or stopped by a signal.
+.It 126
+The
+.Ar utility
+was found but could not be invoked.
+.It 127
+The
+.Ar utility
+could not be found.
+.It 1
+Some other error occurred.
+.El
+.Sh SEE ALSO
+.Xr echo 1 ,
+.Xr find 1
+.Sh STANDARDS
+The
+.Nm
+utility is expected to be
+.St -p1003.2
+compliant.
+.Sh HISTORY
+The meaning of 123, 124, and 125 exit values were taken from GNU xargs.
