.Sh DESCRIPTION
-With an argument naming an existing
-.Ar file ,
-.Nm accton
-causes system accounting information for every process executed
-to be placed at the end of the file. If no argument is given,
-accounting is turned off.
+The
+.Nm
+utility is used
+for switching system accounting on or off.
+If called with the argument
+.Ar acctfile ,
+system accounting is enabled.
+The
+.Ar acctfile
+specified must exist prior to starting system accounting, or
+.Nm
+will return an error.
+A record of every process that is started by the
+.Xr execve 2
+system call and then later exits the system is stored in
+.Ar acctfile .
+The
+.Xr sa 8
+command may be used to examine the accounting records.
+If no arguments are given, system accounting is disabled.

-.Dt AUDITD 8
-.Os "Mac OS X"
-.Sh NAME
-.Nm auditd
-.Nd audit log management daemon
-.Sh SYNOPSIS
-.Nm auditd
-.Op Fl dhs
-.Sh DESCRIPTION
-The
-.Nm
-daemon responds to requests from the audit(1) utility and notifications
-from the kernel. It manages the resulting audit log files and specified
-log file locations.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl d
-Starts the daemon in debug mode - it will not daemonize.
-.It Fl h
-Specifies that if auditing cannot be performed as specified, the system should
-halt (panic). Normally, the system will attempt to proceed - although individual
-processes may be stopped (see the -s option).
-.It Fl s
-Specifies that individual processes should stop rather than perform operations
-that may cause audit records to be lost due to log file full conditions
-.El
-.Sh NOTE
-.Pp
-To assure uninterrupted audit support, the
-.Nm auditd
-daemon should not be started and stopped manually. Instead, the audit(1) command
-should be used to inform the daemon to change state/configuration after altering
-the audit_control file.
-.Pp
-Sending a SIGHUP to a running
-.Nm auditd
-daemon will force it to exit.
-.Sh FILES
-.Bl -tag -width "/var/audit" -compact
-.It Pa /var/audit
-Default directory for storing audit log files.
-.El
-.Sh SEE ALSO
-.Xr audit 1

-.Sh NAME
-.Nm kgmon
-.Nd generate a dump of the operating system's profile buffers
-.Sh SYNOPSIS
-.Nm kgmon
-.Op Fl bhpr
-.Op Fl M core
-.Op Fl N system
-.Sh DESCRIPTION
-.Nm Kgmon
-is a tool used when profiling the operating system.
-When no arguments are supplied,
-.Nm kgmon
-indicates the state of operating system profiling as running,
-off, or not configured.
-(see
-.Xr config 8 )
-If the
-.Fl p
-flag is specified,
-.Nm kgmon
-extracts profile data from the operating system and produces a
-.Pa gmon.out
-file suitable for later analysis by
-.Xr gprof 1 .
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.\" ==========
-.It Fl b
-Resume the collection of profile data.
-.\" ==========
-.It Fl h
-Stop the collection of profile data.
-.\" ==========
-.It Fl M
-Extract values associated with the name list from the specified core
-instead of the default ``/dev/kmem''.
-.\" ==========
-.It Fl N
-Extract the name list from the specified system instead of the
-default ``/vmunix''.
-.\" ==========
-.It Fl p
-Dump the contents of the profile buffers into a
-.Pa gmon.out
-file.
-.\" ==========
-.It Fl r
-Reset all the profile buffers.
-If the
-.Fl p
-flag is also specified, the
-.Pa gmon.out
-file is generated before the buffers are reset.
-.El
-.Pp
-If neither
-.Fl b
-nor
-.Fl h
-is specified, the state of profiling collection remains unchanged.
-For example, if the
-.Fl p
-flag is specified and profile data is being collected,
-profiling will be momentarily suspended,
-the operating system profile buffers will be dumped,
-and profiling will be immediately resumed.
-.Sh FILES
-.Bl -tag -width /dev/kmemx -compact
-.It Pa /vmunix
-the default system
-.It Pa /dev/kmem
-the default memory
-.El
-.Sh SEE ALSO
-.Xr gprof 1 ,
-.Xr config 8
-.Sh DIAGNOSTICS
-Users with only read permission on
-.Pa /dev/kmem
-cannot change the state
-of profiling collection.
-If profiling is in progress,
-they can get a
-.Pa gmon.out
-file containing a warning that the data may be inconsistent.
-.Sh HISTORY
-The
-.Nm kgmon
-command appeared in
-.Bx 4.2 .

-Rules for demangling IOKit symbols
-
-In Darwin versions 1.0 through at least 5.2, IOKit is compiled using
-GCC version 2. GCC 2's C++ symbol mangling algorithm ultimately
-derives from the basic scheme described in the Annotated C++ Reference
-Manual (ARM), section 7.2.1c, with a number of changes, mostly due to
-the expansion of the language since the ARM was published in 1990.
-
-This description is not complete. It omits RTTI, thunks, and
-templates, since they are not allowed in IOKit. The description also
-mentions mangled name constructs that are not disallowed in IOKit, but
-that as of Jan 2002, did actually appear in any symbol in the base
-system.
-
-A mangled name basically consists of a function name followed
-by two underscores, optionally followed by a signature computed
-from the function's argument types. (Note that in Darwin, the
-compiler adds an additional underscore to all C and C++ symbols.
-The description assumes this has been removed.)
-
-<special_or_name> ::= <gnu_special>
- | <mangled_name>
-
-<mangled_name> ::= <prefix> [ <signature> ]
-
-<prefix> ::= [ "_GLOBAL_" [ID] "__" ] <function_name> "__" [ <opinfo> ]
-
-<function_name> ::= <char> <char>*
- | NULL
-
-Questions for Stan (@@@Stan@@@)
-1> A valid <opinfo> implies a null function name.
-2> I wonder if an <opinfo> is mutually exclusive with a <function_name> perhaps something like :-
-<prefix> ::= [ "_GLOBAL_" ("I"|"D") "__" ] ((<function_name> "__") | <opinfo>)
-3> Do constructors turn up as an opinfo or a NULL function name?
-
-The optional "_GLOBAL_"("I"|"D")"__" sequence indicates global constructors
-and destructors, but in practice these do not appear with the mach-o Apple 2.95
-
-A Null <function_name> indicates a constructor or an operator.
-
-Since <function_name> may include trailing underscores, the demangler
-should scan forward until a non-underscore is seen, and then take the
-last two as the separator between name and signature.
-
-<function_name> may also include any number of leading underscores, so
-the demangler needs to add those to <function_name> and look for the
-"__" following the name.
-
-<gnu_special> ::= ("_._"|"_$_" ) <class_name> ; destructor
- | "__vt_" <class_name> ; virtual table
- | "_" <class_name> ("."|"$") <varname> ; Variable
-
-<class_name> ::= <counted_class_name>
- | "Q" <qualified_name>
- | "K" <qualified_name> ; ignored and illegal

-Questions for Stan (@@@Stan@@@)
-1> What the hell is The "type" & "__op" stuff?
-
-IOKit has so far only been observed to use operations new ("nw") and
-delete ("dl").
-
-The signature is a concatenated list of elements, which are usually
-argument types, but may include other sorts of things.
-
-<signature> ::= <qualifier>* <s_element> <argument_types>
-
-<s_element> ::= <class_name>
- | "S"
- | "F" <argument_types> [ "_" <return_type> ]
-
-Questions for Stan (@@@Stan@@@)
-1> I think the 'B' phrase should probably read '| "B" <index>'?
-2> Ambiguous productions for signature
- OSObject::func(struct timeval fred) => _func__8OSObject7timeval
- signature could be parsed as
- <s_element> <s_element> or <s_element> <argument_types>
- I believe the second one must be the valid production.
-
-<count> ::= <digit> <digit>*
-
-<varname> :: <name>
-
-<name> ::= <char> <char>*
-
-The <count> is the number of characters in <name>.
-
-Argument types are a concatenated sequence of types.
-
-<argument_types> ::= # Empty
- | <arg_type>+
-<arg_type> ::= <type> [ "n" <index> ]
- | "N" <count> <pos>
- | "T" <index>
-
-The "N" repeats and "T" references to already-seen typescan only
-appear if -fno-squangle (no squashed mangling), and in practice aren't
-seen in IOKit symbols.
-
-<index> ::= <digit> | <digit> <digit> <digit>* "_"
-
-Return types are just like any other sort of type.
-
-<return_type> ::= <type>
-
-Types consist of a variable number of declarators in front of a basic
-type.
-
-<type> ::= <declarator>* <base_type>
-
-<declarator> ::= "P" ; pointer
- | "p" ; pointer (but never occurs?)
- | "R" ; reference (&)
- | "A" <count> ; array
- | "T" <index>
- | "O" <count>
- | <qualifier>
-
-The "A" <count> production can produce an ambigous output if it is followed by a counted class name or structure name.
-
-The "T" reference to a type does not appear in IOKit symbols, nor do
-the "M" and "O" declarators.
-
-<base_type> ::= <function_type> ; function
- | <method_type> ; method
- | <type_qualifier>* <fund_type_id>
-
-<function_type> ::= "F" <argument_types> "_" <type>
-
-<method_type> ::= "M" <class_name> <function_type>
-
-A qualified name consists of a count of types, followed by all the
-types concatenated together. For instance, Namespace::Class is
-Q29Namespace5Class. For more than 9 types (which has not yet occurred
-in IOKit), the multi-digit count is surrounded by underscores.
-
-Questions for Stan (@@@Stan@@@)
-1> Can the types in a qualified name really be generic types or can the set be restricted to just counted class names?
-
-<q_count> ::= <digit> | "_" <digit> <digit>* "_"
-
-Fundamental types are single letters representing standard built-in
-types, optionally preceded by type qualifiers for properties like
-signedness and constness. For instance, CUi is a const unsigned int.
-
-<type_qualifier> ::= "S" ; signed (chars only)
- | "U" ; unsigned (any integral type)
- | "J" ; __complex
- | <qualifier>
-
-<fund_type_id> ::= <class_name>
- | "b" ; bool
- | "c" ; char
- | "d" ; double
- | "f" ; float
- | "i" ; int
- | "l" ; long
- | "r" ; long double
- | "s" ; short
- | "v" ; void
- | "w" ; wchar_t
- | "x" ; long long
- | "G" <count> ; ?????
- | "e" ; ellipsis
-
-"G" does not appear in IOKit symbols in this context.
-
-<qualifier> ::= "C" ; const
- | "V" ; volatile
- | "u" ; restrict (C99)
- | "G" ; struct/union/enum unused by gcc3
-
-The restrict qualifier has not appeared in IOKit symbols.

-.Dt KMODLOAD 8
-.Os FreeBSD
-.Sh NAME
-.Nm kmodload
-.Nd loads and starts a kernel module
-.Sh SYNOPSIS
-.Nm kmodload
-.Op Fl v
-.Op Fl k Ar kernel_file
-.Op Fl d Ar dependency_file
-.Op Fl o Ar symbol_file
-.Ar module_file
-.Sh DESCRIPTION
-.Nm kmodload
-is deprecated; use
-.Xr kextload 8 ,
-instead.
-.Pp
-The
-.Nm kmodload
-command loads the file
-.Ar module_file
-into the kernel and starts its execution.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.\" ==========
-.It Fl d Ar dependency_file
-Add symbols from
-.Ar dependency_file
-to kernel symbols, prior to linking of
-.Ar module_file .
-The file
-.Ar dependency_file
-must already be loaded.
-.\" ==========
-.It Fl k Ar kernel_file
-Use an alternate file
-.Ar kernel_file ,
-instead of the default file (/mach), for linking
-.Ar module_file .
-.\" ==========
-.It Fl o Ar symbol_file
-Create a file named
-.Ar symbol_file
-that contains statically-linked output suitable
-for remote debugging use with
-.Xr gdb 1 .
-.\" ==========
-.It Fl v
-Be more verbose.
-.El
-.Sh FILES
-.Bl -tag -width /modules -compact
-.It Pa /System/Library/Extensions
-directory containing loadable kernel modules.
-.Sh DIAGNOSTICS
-The
-.Nm kmodload
-utility exits with a status of 0 on success.
-A status of 1 indicates a usage error.
-A status of 2 indicates a indicates a permissions error.
-A status of 3 indicates a problem with linking the module.
-A status of 4 indicates a internal or system error.
-A status of 5 indicates the module has already been loaded.
-.Sh SEE ALSO
-.Xr gdb 1 ,
-.Xr kmodstat 8 ,
-.Xr kmodsyms 8 ,
-.Xr kmodunload 8
-.Sh HISTORY
-The
-.Nm kmodload
-command is based on the command kldload written by
-.An Doug Rabson Aq dfr@FreeBSD.org

-.Dt KMODSYMS 8
-.Os FreeBSD
-.Sh NAME
-.Nm kmodsyms
-.Nd creates a statically-linked symbol file for remote debugging
-.Sh SYNOPSIS
-.Nm kmodsyms
-.Op Fl v
-.Op Fl k Ar kernel_file
-.Op Fl d Ar dependency_file
-.Fl o Ar symbol_file
-.Ar module_file
-.Nm kmodsyms
-.Op Fl v
-.Fl k Ar kernel_file
-.Op Fl d Ar dependency_file@address
-.Fl o Ar symbol_file
-.Ar module_file@address
-.Sh DESCRIPTION
-.Nm kmodsyms
-is deprecated; use
-.Xr kextload 8 ,
-instead.
-.Pp
-The
-.Nm kmodsyms
-creates a statically-linked symbol file for remote debugging using
-.Ar module_file[@address] .
-If an address is specified for either the
-.Ar module_file
-or
-.Ar dependency_file
-they both must have the address tag.
-If addresses are specified,
-it is assumed that the command is being run on a different machine
-with a potentially different kernel.
-Thus, the
-.Ar kernel_file
-argument is also required.
-If addresses are not specified,
-they taken from the currently running host machine.
-.Pp
-The following options are available:
-.Bl -tag -width indent
-.\" ==========
-.It Fl d Ar dependency_file[@address]
-Add symbols from
-.Ar dependency_file
-to kernel symbols prior to linking of
-.Ar module_file .
-The file
-.Ar dependency_file
-must already be loaded.
-.\" ==========
-.It Fl k Ar kernel_file
-Use an alternate file
-.Ar kernel_file ,
-instead of the default file (/mach) for linking
-.Ar module_file .
-.\" ==========
-.It Fl o Ar symbol_file
-Creates file named
-.Ar symbol_file
-that contains statically linked output suitable
-for remote debugging use with
-.Xr gdb 1 .
-.\" ==========
-.It Fl v
-Be more verbose.
-.El
-.Sh FILES
-.Bl -tag -width /modules -compact
-.It Pa /System/Library/Extensions
-directory containing loadable kernel modules.
-.Sh DIAGNOSTICS
-The
-.Nm kmodsyms
-utility exits with a status of 0 on success.
-A status of 1 indicates a usage error.
-A status of 2 indicates a indicates a permissions error.
-A status of 3 indicates a problem with linking the module.
-A status of 4 indicates a internal or system error.
-.Sh SEE ALSO
-.Xr kmodload 8 ,
-.Xr kmodstat 8 ,
-.Xr kmodunload 8
-.Sh HISTORY
-The
-.Nm kmodsyms
-command is based on the command kldload, written by
-.An Doug Rabson Aq dfr@FreeBSD.org

.Nm login
.Nd log into the computer
.Sh SYNOPSIS
-.Nm login
+.Nm
.Op Fl pq
.Op Fl h Ar hostname
.Op Ar user
-.Nm login
+.Nm
.Fl f
.Op Fl lpq
.Op Fl h Ar hostname
.Op Ar user Op Ar prog Op Ar args...
.Sh DESCRIPTION
The
-.Nm login
+.Nm
utility logs users (and pseudo-users) into the computer system.
.Pp
If no user is specified, or if a user is specified and authentication
of the user fails,
-.Nm login
+.Nm
prompts for a user name.
-Authentication of users is done via passwords.
+Authentication of users is configurable via
+.Xr pam 8 .
+Password authentication is the default.
.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.\" ==========
+The following options are available:
+.Bl -tag -width indent
.It Fl f
-The
-.Fl f
-option is used when a user name is specified to indicate that proper
+When a user name is specified, this option indicates that proper
authentication has already been done and that no password need be
requested.
This option may only be used by the super-user or when an already
option, an alternate program (and any arguments) may be run instead of the
user's default shell.
The program and arguments follows the user name.
-.\" ==========
.It Fl h
-The
-.Fl h
-option specifies the host from which the connection was received.
+Specify the host from which the connection was received.
It is used by various daemons such as
-.Xr telnetd 8 .
+.Xr telnetd 8 .
This option may only be used by the super-user.
-.\" ==========
.It Fl l
Tells the program executed by
-.Nm login
+.Nm
that this is not a login session (by convention, a login session is
signalled to the program with a hyphen as the first character of
.Em argv[0] ;
this option disables that), and prevents it from chdir(2)ing to the user's home directory.
The default is to add the hyphen (this is a login session).
-.\" ==========
.It Fl p
By default,
-.Nm login
+.Nm
discards any previous environment.
The
.Fl p
option disables this behavior.
-.\" ==========
.It Fl q
This forces quiet logins, as if a
.Pa .hushlogin
If the file
.Pa /etc/nologin
exists,
-.Nm login
+.Nm
dislays its contents to the user and exits.
This is used by
.Xr shutdown 8
to prevent users from logging in when the system is about to go down.
.Pp
Immediately after logging a user in,
-.Nm login
+.Nm
displays the system copyright notice, the date and time the user last
logged in, the message of the day as well as other information.
If the file
-.Dq Pa .hushlogin
-exists in the user's home directory or
+.Pa .hushlogin
+exists in the user's home directory, all of these messages are suppressed.
.Fl q
is specified, all of these messages are suppressed.
This is to simplify logins for non-human users, such as
.Xr uucp 1 .
-.Nm Login
+.Nm
then records an entry in
.Xr utmpx 5
and the like, and executes the user's command interpreter (or the program
.Fl f
is specified).
.Pp
-Login enters information into the environment (see
+The
+.Nm
+utility enters information into the environment (see
.Xr environ 7 )
specifying the user's home directory (HOME), command interpreter (SHELL),
search path (PATH), terminal type (TERM) and user name (both LOGNAME and
USER).
.Pp
-The standard shells,
-.Xr csh 1
-and
-.Xr sh 1 ,
-do not fork before executing the
-.Nm login
-utility.
+Some shells may provide a builtin
+.Nm
+command which is similar or identical to this utility.
+Consult the
+.Xr builtin 1
+manual page.
+.Pp
+The
+.Nm
+utility will submit an audit record when login succeeds or fails.
+Failure to determine the current auditing state will
+result in an error exit from
+.Nm .

.Sh SYNOPSIS
-.Nm newgrp
+.Nm
.Op Fl l
.Op Ar group
.Sh DESCRIPTION
The
-.Nm newgrp
-utility creates a new shell execution environment
-with modified real and effective group IDs.
+.Nm
+utility creates a new shell execution environment with modified
+real and effective group IDs.
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl l
Simulate a full login.
-The environment and umask are set to what would be expected
-if the user actually logged in again.
+The environment and umask are set to what would be expected if the user
+actually logged in again.
.El
.Pp
If the
.Ar group
-operand is present, a new shell is started
-with the specified effective and real group IDs.
-The user will be prompted for a password
-if they are not a member of the specified group.
+operand is present, a new shell is started with the specified effective
+and real group IDs.
+The user will be prompted for a password if they are not a member of the
+specified group.
.Pp
-Otherwise, the real, effective, and supplementary group IDs
-are restored to those from the current user's password database entry.
-.Sh DIAGNOSTICS
+Otherwise, the real, effective and supplementary group IDs are restored to
+those from the current user's password database entry.
+.Sh EXIT STATUS
The
-.Nm newgrp
+.Nm
utility attempts to start the shell regardless of whether group IDs
were successfully changed.
.Pp
If an error occurs and the shell cannot be started,
-.Nm newgrp
+.Nm
exits >0.
Otherwise, the exit status of
-.Nm newgrp
+.Nm
is the exit status of the shell.

+.Nm nologin
+.Nd disallow logins
+.Sh DESCRIPTION
+Programs such as
+.Xr login 1
+disallow logins if the
+.Nm
+file exists.
+The programs display the contents of
+.Nm
+to the user if possible and interrupt the login sequence.
+This makes it simple to temporarily prevent incoming logins systemwide.
+.Pp
+To disable logins on a per-account basis,
+investigate
+.Xr nologin 8 .
+.Sh SECURITY
+The
+.Nm
+file is ignored for user root by default.
+.Sh IMPLEMENTATION NOTES
+The
+.Nm
+feature is implemented through
+.Xr login.conf 5 ,
+which allows to change the pathname of the
+file and to extend the list of users
+exempt from temporary login restriction.
+.Pp
+PAM-aware programs can be selectively configured to respect
+.Nm
+using the
+.Xr pam_nologin 8
+module via
+.Xr pam.conf 5 .
+.Pp
+The
+.Nm
+file will be removed at system boot if it resides in
+.Pa /var/run
+and
+.Va cleanvar_enable
+is set to
+.Dq Li YES
+in
+.Xr rc.conf 5 ,
+which is default.
+Therefore system reboot can effectively re-enable logins.

-An automatic consistency check of the file systems will be performed,
-and unless this fails, the system will resume multi-user operations.
-.Pp
-.Sy Cold starts.
-On an HP300, the boot procedure uses the boot ROM to load a boot program
-from an
-.Tn LIF
-format directory at the beginning of an attached disk.
-The
-.Pa /usr/mdec
-directory contains a disk boot programs which should be placed in a
-new pack automatically by
-.Xr newfs 8
-when the ``a'' partition file system on the pack is created.
-.Pp
-This
-.Em boot
-program
-finds the corresponding file on the given device
-.Pf ( Ar vmunix
-by default),
-loads that file into memory,
-and starts the program at the entry address specified in the program header.
-.Pp
-The boot program can be interrupted by typing `^C' (ctrl-C).
-This will force the boot program to interactively prompt for a system to boot.
-If not interrupted, it will boot from the device from which the boot
-program itself was loaded.
-.Pp
-The file specifications used for an interactive boot are of the form:
-.Pp
-.Dl device(unit, minor)
-.Pp
-where
-.Ar device
-is the type of the device to be searched,
-.Ar unit
-is 8 * the hpib number plus the unit number of the disk or tape,
-and
-.Ar minor
-is the disk partition or tape file number.
-Normal line editing characters can be used when typing the file specification.
-Currently, ``rd'' and ``sd'' are the only valid
-.Ar device
-specifiers.
-.Pp
-For example,
-to boot from the `a' file system of unit 0 on HP-IB 2,
-type
-.Ql rd(16, 0)vmunix
-to the boot prompt.
-For tapes, the minor device number gives a file offset.
-.Pp

-known as hard disk controller 1, drive 0).
-The automatic boot will attempt to load
-.Pa vmunix
-from partition A of either the floppy or the hard disk.
-This boot may be aborted by typing any character on the keyboard repeatedly
-(four or five times at least) during the operating system load phase, after
-which the bootstrap will prompt for the file that you wish to load instead.
-.Pp
-One exception to this is the

-The boot flags for an autoboot are 0, and 3 for the successive boot after
-an aborted autoboot sequence.
-No other provison is made for setting boot flags (yet).
-A specific device or bootstrap file may be used; for example,

-which is normally a copy of one of the standard multi-user boot scripts,
-but which may be modified to perform other actions
-or to boot from a different unit.
-The situation on the 8600 is similar, with scripts loaded from the console RL02.
-.Pp
-Giving the command
-.Pp
-.Dl >>>BOOT HPM
-.Pp
-would boot the system from (e.g.) an RP06 and run the automatic consistency
-check as described in
-.Xr fsck 8 .
-(Note that it may
-be necessary to type control-P
-and halt the processor
-to gain the attention of the
-.Tn LSI-11
-before getting the >>> prompt.)
-The command
-.Pp
-.Dl >>>BOOT ANY
-.Pp
-invokes a version of the boot program in a way which allows you to
-specify any system as the system to be booted.
-It reads from the console a device specification (see below) followed
-immediately by a pathname.
-.Pp
-The scripts may be modified for local configuration if necessary.
-The flags are placed in register 11 (as defined in
-.Aq Pa sys/reboot.h ) .
-The boot device is specified in register 10.
-The encoding of this register is also defined in
-.Aq Pa sys/reboot.h .
-The current encoding has a historical basis, and is shown in the following
-table:
-.Pp
-.Bd -unfilled -offset indent -compact
-bits usage
-0-7 boot device type (the device major number)
-8-15 disk partition
-16-19 drive unit
-20-23 controller number
-24-27 adaptor number (UNIBUS or MASSBUS as appropriate)
-.Ed
-.Pp
-The adaptor number corresponds to the normal configuration on the 11/750,
-and to the order in which adaptors are found on the 11/780 and 8600
-(generally the same as the numbers used by
-.Tn UNIX ) .
-.Pp
-On an 11/750, the reset button will boot from the device
-selected by the front panel boot device switch. In systems
-with RK07's, position B normally selects the RK07 for boot.
-This will boot multi-user. To boot from RK07 with boot flags you
-may specify
-.Pp
-.Bd -unfilled -offset indent -compact
-.Li \&>>>B/ Ns Fl n No DMA0
-.Ed
-.Pp
-where, giving a
-.Ar n
-of 1 causes the boot program
-to ask for the name of the system to be bootstrapped,
-giving a
-.Ar n
-of 2 causes the boot program to come up single
-user, and a
-.Ar n
-of 3 causes both of these actions to occur.
-The ``DM'' specifies RK07, the ``A'' represents the adaptor number
-.Pf ( Tn UNIBUS
-or
-.Tn MASSBUS ) ,
-and the ``0'' is the drive unit number.
-Other disk types which may be used are DB
-.Pq Tn MASSBUS ,
-DD (TU58),
-and DU
-.Pf ( Tn UDA-50/RA
-disk).
-A non-zero disk partition can be used by adding (partition times 1000 hex)
-to
-.Ar n .
-.Pp
-The boot procedure on the Micro
-.Tn VAX
-II
-is similar.
-A switch on the back panel sets the power-up action
-to autoboot or to halt.
-When halted, the processor may be booted using the same syntax
-as on the 11/750.
-.Pp
-The 11/750 boot procedure uses the boot roms to load block 0 off of
-the specified device. The /usr/mdec directory contains a number
-of bootstrap programs for the various disks which should be placed
-in a new pack by
-.Xr disklabel 8 .
-Similarly, the Micro
-.Tn VAX
-II boot procedure loads a boot parameter block
-from block 0 of the disk.
-The
-.Xr rdboot
-.Dq bootstrap
-contains the correct parameters for an
-.Tn MSCP
-disk such
-as the RD53.
-.Pp
-On any processor, the
-.Em boot
-program
-finds the corresponding file on the given device
-.Pf ( Pa vmunix
-by default), loads that file
-into memory location zero, and starts the program at the entry address
-specified in the program header (after clearing off the high bit
-of the specified entry address).
-.Pp
-The file specifications used with
-.Dq BOOT ANY
-or
-.Dq \&B/3
-are of the form:
-.Pp
-.Dl device(adaptor,controller,unit,minor)
-.Pp
-where
-.Ar device
-is the type of the device to be searched,
-.Ar adaptor
-is the
-.Tn UNIBUS
-or
-.Tn MASSBUS
-number of the adaptor to which the device is attached,
-.Ar controller
-is the unit number of the controller or
-.Tn MASSBUS
-tape formatter on that adaptor,
-.Ar unit
-is the unit number of the disk or transport slave unit of the tape,
-and
-.Ar minor
-is the disk partition or tape file number.
-Leading adaptor or controller numbers default to 0.
-Normal line editing characters can be used when typing the file specification.
-The following list of supported devices may vary from installation to
-installation:
-.Pp
-.Bd -unfilled -offset indent -compact
-hp MASSBUS disk drive
-up UNIBUS storage module drive
-ht TE16,TU45,TU77 on MASSBUS
-kra storage module on a KDB50
-mt TU78 on MASSBUS
-hk RK07 on UNIBUS
-ra storage module on a MSCP-compatible UNIBUS controller
-rb storage module on a 730 IDC
-rl RL02 on UNIBUS
-tm TM11 emulation tape drives on UNIBUS
-tms TMSCP-compatible tape
-ts TS11 on UNIBUS
-ut UNIBUS TU45 emulator
-.Ed
-.Pp
-For example,
-to boot from a file system which starts at cylinder 0
-of unit 0 of a
-.Tn MASSBUS
-disk, type
-.Ql hp(0,0)vmunix
-to the boot prompt;
-.Ql hp(2,0,1,0)vmunix
-would specify drive 1 on
-.Tn MASSBUS
-adaptor 2;
-.Ql up(0,0)vmunix
-would specify a
-.Tn UNIBUS
-drive,
-.Ql hk(0,0)vmunix
-would specify
-an RK07 disk drive,
-.Ql ra(1,0,0,0)vmunix
-would specify a
-.Tn UDA50
-disk drive on a second
-.Tn UNIBUS ,
-and
-.Ql rb(0,0)vmunix
-would specify a
-disk on a 730
-.Tn IDC .
-For tapes, the minor device number gives a file offset;
-.Ql mt(1,2,3,4)
-would specify the fifth file on slave 3 of the formatter
-at
-.Ql drive
-2 on mba 1.
-.Pp
-On an 11/750 with patchable control store,
-microcode patches will be installed by
-.Em boot
-if the file
-.Pa psc750.bin
-exists in the root of the filesystem from which the system is booted.
-.Pp
-In an emergency, the bootstrap methods described in the paper
-.%T Installing and Operating 4.3bsd
-can be used to boot from a distribution tape.

.Op Ar
.Sh DESCRIPTION
The
-.Nm sa
+.Nm
utility reports on, cleans up,
and generally maintains system
accounting files.
.Pp
The
-.Nm sa
+.Nm
utility is able to condense the information in
.Pa /var/account/acct
into the summary files
.Pa /var/account/acct .
After each file is read, if the summary
files are being updated, an updated summary will
-be saved to disk. Only one report is printed,
+be saved to disk.
+Only one report is printed,
after the last file is processed.
.Pp
The labels used in the output indicate the following, except
where otherwise specified by individual options:
.Bl -tag -width k*sec
-.\" ==========
.It Dv avio
Average number of I/O operations per execution
-.\" ==========
.It Dv cp
Sum of user and system time, in minutes
-.\" ==========
.It Dv cpu
Same as
.Dv cp
-.\" ==========
.It Dv k
CPU-time averaged core usage, in 1k units
-.\" ==========
.It Dv k*sec
CPU storage integral, in 1k-core seconds
-.\" ==========
.It Dv re
Real time, in minutes
-.\" ==========
.It Dv s
System time, in minutes
-.\" ==========
.It Dv tio
Total number of I/O operations
-.\" ==========
.It Dv u
User time, in minutes
.El
.Pp
The options to
-.Nm sa
+.Nm
are:
.Bl -tag -width Ds
-.\" ==========
.It Fl a
List all command names, including those containing unprintable
-characters and those used only once. By default,
-.Nm sa
+characters and those used only once.
+By default,
+.Nm
places all names containing unprintable characters and
those used only once under the name ``***other''.
-.\" ==========
.It Fl b
If printing command statistics, sort output by the sum of user and system
time divided by number of calls.
-.\" ==========
.It Fl c
In addition to the number of calls and the user, system and real times
for each command, print their percentage of the total over all commands.
-.\" ==========
-.It Fl D
-If printing command statistics, sort and print by the total number
-of disk I/O operations.
-.\" ==========
.It Fl d
If printing command statistics, sort by the average number of disk
-I/O operations. If printing user statistics, print the average number of
+I/O operations.
+If printing user statistics, print the average number of
disk I/O operations per user.
-.\" ==========
+.It Fl D
+If printing command statistics, sort and print by the total number
+of disk I/O operations.
.It Fl f
Force no interactive threshold comparison with the
.Fl v
option.
-.\" ==========
.It Fl i
Do not read in the summary files.
-.\" ==========
.It Fl j
Instead of the total minutes per category, give seconds per call.
-.\" ==========
-.It Fl K
-If printing command statistics, print and sort by the cpu-storage integral.
-.\" ==========
.It Fl k
If printing command statistics, sort by the cpu-time average memory
-usage. If printing user statistics, print the cpu-time average
+usage.
+If printing user statistics, print the cpu-time average
memory usage.
-.\" ==========
+.It Fl K
+If printing command statistics, print and sort by the cpu-storage integral.
.It Fl l
Separate system and user time; normally they are combined.
-.\" ==========
.It Fl m
Print per-user statistics rather than per-command statistics.
-.\" ==========
.It Fl n
Sort by number of calls.
-.\" ==========
+.It Fl P Ar file
+Use the specified
+.Ar file
+for accessing the per-command accounting summary database,
+instead of the default
+.Pa /var/account/savacct .
.It Fl q
Create no output other than error messages.
-.\" ==========
.It Fl r
Reverse order of sort.
-.\" ==========
.It Fl s
Truncate the accounting files when done and merge their data
into the summary files.
-.\" ==========
.It Fl t
For each command, report the ratio of real time to the sum
of user and system cpu times.
If the cpu time is too small to report, ``*ignore*'' appears in
this field.
-.\" ==========
+.It Fl U Ar file
+Use the specified
+.Ar file
+for accessing the per-user accounting summary database,
+instead of the default
+.Pa /var/account/usracct .
.It Fl u
Superseding all other flags, for each entry
in the accounting file, print the user ID, total seconds of cpu usage,
total memory usage, number of I/O operations performed, and
command name.
-.\" ==========
.It Fl v Ar cutoff
For each command used
.Ar cutoff
times or fewer, print the command name and await a reply
-from the terminal. If the reply begins with ``y'', add
-the command to the category ``**junk**''. This flag is
+from the terminal.
+If the reply begins with ``y'', add
+the command to the category ``**junk**''.
+This flag is
used to strip garbage from the report.

+The number of
calls, the total elapsed time in minutes, total cpu and user time
in minutes, average number of I/O operations, and CPU-time

-The VM system does not record the CPU storage integral.
.Sh CAVEATS
While the behavior of the options in this version of
-.Nm sa
+.Nm
was modeled after the original version, there are some intentional
-differences and undoubtedly some unintentional ones as well. In
+differences and undoubtedly some unintentional ones as well.
+In
particular, the
.Fl q
option has been added, and the
option now understands more options than it used to.
.Pp
The formats of the summary files created by this version of
-.Nm sa
+.Nm
are very different from the those used by the original version.
This is not considered a problem, however, because the accounting record
format has changed as well (since user ids are now 32 bits).

+Output version information and exit.
.It Fl D
Do not automatically create directories.
If the input file(s) specify
If
.Fl D
is specified,
-.Nm zic
+.Nm
will instead error out immediately.
-.\" ==========
.It Fl d Ar directory
Create time conversion information files in the named directory rather than
in the standard directory named below.
-.\" ==========
.It Fl g Ar group
After creating each output file, change its group ownership to the
specified
.Ar group
(which can be either a name or a numeric group ID).
-.\" ==========
.It Fl L Ar leapsecondfilename
Read leap second information from the file with the given name.
If this option is not used,
no leap second information appears in output files.
-.\" ==========
.It Fl l Ar timezone
Use the given
.Ar time zone
as local time.
The
-.Nm zic
+.Nm
utility will act as if the input contained a link line of the form
-.Bd -literal -offset indent
-.No "Link timezone localtime
-.Ed
+.Pp
+.D1 No "Link timezone localtime"
+.Pp
(Note that this action has no effect on
.Fx ,
since the local time zone is specified in
.Pa /etc/localtime
and not
.Pa /usr/share/zoneinfo/localtime . )
-.\" ==========
.It Fl m Ar mode
After creating each output file, change its access mode to
.Ar mode .
Both numeric and alphabetic modes are accepted
(see
.Xr chmod 1 ) .
-.\" ==========
.It Fl p Ar timezone
Use the given
.Ar "time zone" Ns 's
rules when handling POSIX-format
time zone environment variables.
The
-.Nm zic
+.Nm
utility will act as if the input contained a link line of the form
-.Bd -literal -offset indent
-.No "Link timezone posixrules
-.Ed
-.\" ==========
-.It Fl s
-Limit time values stored in output files to values that are the same
-whether they're taken to be signed or unsigned.
-You can use this option to generate SVVS-compatible files.
-.\" ==========
+.Pp
+.D1 No "Link timezone posixrules"
.It Fl u Ar user
After creating each output file, change its owner to
.Ar user
of years representable by
.Xr time 3
values.
-.\" ==========
-.It Fl -version
-Output version information and exit.
-.\" ==========
+.It Fl s
+Limit time values stored in output files to values that are the same
+whether they are taken to be signed or unsigned.
+You can use this option to generate SVVS-compatible files.
.It Fl y Ar command
Use the given
.Ar command
An unquoted sharp character (#) in the input introduces a comment which extends
to the end of the line the sharp character appears on.
White space characters and sharp characters may be enclosed in double quotes
-(") if they're to be used as part of a field.
+(") if they are to be used as part of a field.
Any line that is blank (after comment stripping) is ignored.
Non-blank lines are expected to be of one of three types:
rule lines, zone lines, and link lines.
If
.Em TYPE
is something else, then
-.Nm zic
+.Nm
executes the command
.Li yearistype Ar year Ar type
to check the type of a year:
