+.Sh SYNOPSIS
+.Nm gzexe
+.Op Fl d
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility uses
+.Xr gzip 1
+to compress executables, producing executables that decompress on-the-fly
+when executed.
+This saves disk space, at the cost of slower execution times.
+The original executables are saved by copying each of them to a file with
+the same name with a
+.Sq ~
+suffix appended.
+After verifying that the compressed executables work as expected, the backup
+files can be removed.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl d
+Decompress executables previously compressed by
+.Nm .
+.El
+.Pp
+The
+.Nm
+program refuses to compress non-regular or non-executable files,
+files with a setuid or setgid bit set, files that are already
+compressed using
+.Nm
+or programs it needs to perform on-the-fly decompression:
+.Xr sh 1 ,
+.Xr mktemp 1 ,
+.Xr rm 1 ,
+.Xr echo 1 ,
+.Xr tail 1 ,
+.Xr gzip 1 ,
+and
+.Xr chmod 1 .
+.Sh SEE ALSO
+.Xr gzip 1
+.Sh CAVEATS
+The
+.Nm
+utility replaces files by overwriting them with the generated
+compressed executable.
+To be able to do this, it is required that the original files are writable.

+.Sh DESCRIPTION
+The
+.Nm
+program compresses and decompresses files using Lempel-Ziv coding
+(LZ77).
+If no
+.Ar files
+are specified,
+.Nm
+will compress from standard input, or decompress to standard output.
+When in compression mode, each
+.Ar file
+will be replaced with another file with the suffix, set by the
+.Fl S Ar suffix
+option, added, if possible.
+.Pp
+In decompression mode, each
+.Ar file
+will be checked for existence, as will the file with the suffix
+added.
+Each
+.Ar file
+argument must contain a separate complete archive;
+when multiple
+.Ar files
+are indicated, each is decompressed in turn.
+.Pp
+In the case of
+.Nm gzcat
+the resulting data is then concatenated in the manner of
+.Xr cat 1 .
+.Pp
+If invoked as
+.Nm gunzip
+then the
+.Fl d
+option is enabled.
+If invoked as
+.Nm zcat
+or
+.Nm gzcat
+then both the
+.Fl c
+and
+.Fl d
+options are enabled.
+When invoked as
+.Nm zcat ,
+.Dq .Z
+will be appended to all filenames that do not have that suffix.
+.Pp
+This version of
+.Nm
+is also capable of decompressing files compressed using
+.Xr compress 1
+or
+.Xr bzip2 1 .
+.Sh OPTIONS
+The following options are available:
+.Bl -tag -width XXrXXXrecursiveX
+.It Fl 1 , -fast
+.It Fl 2 , 3 , 4 , 5 , 6 , 7 , 8
+.It Fl 9 , -best
+These options change the compression level used, with the
+.Fl 1
+option being the fastest, with less compression, and the
+.Fl 9
+option being the slowest, with optimal compression.
+The default compression level is 6.
+.It Fl c , -stdout , -to-stdout
+This option specifies that output will go to the standard output
+stream, leaving files intact.
+.It Fl d , -decompress , -uncompress
+This option selects decompression rather than compression.
+.It Fl f , -force
+This option turns on force mode.
+This allows files with multiple links, symbolic links to regular files,
+overwriting of pre-existing files, reading from or writing to a terminal,
+and when combined with the
+.Fl c
+option, allowing non-compressed data to pass through unchanged.
+.It Fl h , -help
+This option prints a usage summary and exits.
+.It Fl k , -keep
+Keep (don't delete) input files during compression
+or decompression.
+.It Fl L , -license
+This option prints
+.Nm
+license.
+.It Fl l , -list
+This option displays information about the file's compressed and
+uncompressed size, ratio, uncompressed name.
+With the
+.Fl v
+option, it also displays the compression method, CRC, date and time
+embedded in the file.
+.It Fl N , -name
+This option causes the stored filename in the input file to be used
+as the output file.
+.It Fl n , -no-name
+This option stops the filename and timestamp from being stored in
+the output file.
+.It Fl q , -quiet
+With this option, no warnings or errors are printed.
+.It Fl r , -recursive
+This option is used to
+.Nm
+the files in a directory tree individually, using the
+.Xr fts 3
+library.
+.It Fl S Ar suffix , Fl -suffix Ar suffix
+This option changes the default suffix from .gz to
+.Ar suffix .
+.It Fl t , -test
+This option will test compressed files for integrity.
+.It Fl V , -version
+This option prints the version of the
+.Nm
+program.
+.It Fl v , -verbose
+This option turns on verbose mode, which prints the compression
+ratio for each file compressed.
+.El
+.Sh ENVIRONMENT
+If the environment variable
+.Ev GZIP
+is set, it is parsed as a white-space separated list of options
+handled before any options on the command line.
+Options on the command line will override anything in
+.Ev GZIP .

+.Sh HISTORY
+The
+.Nm
+program was originally written by Jean-loup Gailly, licensed under
+the GNU Public Licence.
+Matthew R. Green wrote a simple front end for
+.Nx 1.3
+distribution media, based on the freely re-distributable zlib library.
+It was enhanced to be mostly feature-compatible with the original
+GNU
+.Nm
+program for
+.Nx 2.0 .
+.Pp
+This implementation of
+.Nm
+was ported based on the
+.Nx
+.Nm ,
+and first appeared in
+.Fx 7.0 .
+.Sh AUTHORS
+.An -nosplit
+This implementation of
+.Nm
+was written by
+.An Matthew R. Green Aq mrg@eterna.com.au
+with unpack support written by
+.An Xin LI Aq delphij@FreeBSD.org .
+.Sh BUGS
+According to RFC 1952, the recorded file size is stored in a 32-bit
+integer, therefore, it can not represent files larger than 4GB.
+This limitation also applies to
+.Fl l
+option of
+.Nm
+utility.

+.Sh NAME
+.Nm zmore
+.Nd view compressed files
+.Sh SYNOPSIS
+.Nm zmore
+.Op Ar flags
+.Op Ar file ...
+.Sh DESCRIPTION
+.Nm
+is a filter that allows the viewing of files compressed with Lempel-Ziv
+encoding.
+Such files generally have a
+.Dq Z
+or
+.Dq gz
+extension (both the
+.Xr compress 1
+and
+.Xr gzip 1
+formats are supported).
+Any
+.Ar flags
+that are specified are passed to the user's preferred
+.Ev PAGER
+(which is
+.Pa /usr/bin/more
+by default).
+.Pp
+When multiple files are specified,
+.Nm
+will pause at the end of each file and present the following prompt to the user:
+.Bd -literal -offset indent
+prev_file (END) - Next: next_file
+.Ed
+.Pp
+Where
+.Sy prev_file
+is the file that was just displayed and
+.Sy next_file
+is the next file to be displayed.
+The following keys are recognized at the prompt:
+.Bl -tag -width "e or q" -offset indent
+.It Ic e No or Ic q
+quit
+.Nm zmore .
+.It Ic s
+skip the next file (or exit if the next file is the last).
+.El
+.Pp
+If no files are specified,
+.Nm
+will read from the standard input.
+In this mode
+.Nm
+will assume
+.Xr gzip 1
+style compression since there is no suffix on which to make a decision.
+.Sh ENVIRONMENT
+.Bl -tag -width "PAGER"
+.It Ev PAGER
+Program used to display files.
+If unset,
+.Pa /usr/bin/more
+is used.
+.El
+.Sh SEE ALSO
+.Xr compress 1 ,
+.Xr less 1 ,
+.Xr more 1

+.Sh SYNOPSIS
+.Nm
+.Op Fl ftv9K
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility uncompresses files compressed by
+.Xr compress 1
+and recompresses them with
+.Xr gzip 1 .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl f
+Overwrite existing
+.Sq .gz
+files.
+Unless this option is specified,
+.Nm
+refuses to overwrite existing files.
+.It Fl t
+Test integrity of the gzipped file before deleting the original file.
+If the integrity check fails, the original
+.Sq .Z
+file is not removed.
+.It Fl v
+Print a report specifying the achieved compression ratios.
+.It Fl 9
+Use the -9 mode of
+.Xr gzip 1 ,
+achieving better compression at the cost of slower execution.
+.It Fl K
+Keep the original
+.Sq .Z
+file if it uses less disk blocks than the gzipped one.
+A disk block is 1024 bytes.
+.El
+.Sh SEE ALSO
+.Xr gzip 1
+.Sh CAVEATS
+The
+.Nm
+utility tries to maintain the file mode of the original file.
+If the original file is not writable, it is not able to do that and
+.Nm
+will print a warning.
