.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.
|
||||
In decompression mode, each
|
||||
.Ar file
|
||||
will be checked for existance, as will the file with the suffix added.
|
||||
.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 d
|
||||
and
|
||||
.Fl c
|
||||
options are enabled.
|
||||
.Sh OPTIONS
|
||||
The following options are available:
|
||||
.Bl -tag -width Sxxxsuffix
|
||||
.It Fl c
|
||||
Thi option specifies that output will go to the standard output stream,
|
||||
leaving files intact.
|
||||
.It Fl d
|
||||
This option selects decompression rather than compression.
|
||||
.It Fl f
|
||||
This option turns on force mode. This allows files with multiple links,
|
||||
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
|
||||
This option prints a usage summary and exits.
|
||||
.It Fl q
|
||||
With this option, no warnings or errors are printed.
|
||||
.It Fl r
|
||||
This option is used to
|
||||
.Nm
|
||||
the files in a directory tree individually, using the
|
||||
.Xr fts 3
|
||||
library.
|
||||
.It Fl S Ar suffix
|
||||
This option changes the default suffix from .gz to
|
||||
.Ar suffix .
|
||||
.It Fl t
|
||||
This option will test compressed files for integrity.
|
||||
.It Fl v
|
||||
This option turns on verbose mode, which prints the compression ratio
|
||||
for each files compressed.
|
||||
.It Fl V
|
||||
This option prints the version of the
|
||||
.Nm
|
||||
program.
|
||||
.It Fl 1
|
||||
.It Fl 2
|
||||
.It Fl 3
|
||||
.It Fl 4
|
||||
.It Fl 5
|
||||
.It Fl 6
|
||||
.It Fl 7
|
||||
.It Fl 8
|
||||
.It Fl 9
|
||||
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.
|
||||
.El
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
program was originally written by Jean-loup Gailly, licensed under the GNU Public
|
||||
Licence. Matthew R. Green wrote this front-end for the freely
|
||||
distribution zlib compression library, for
|
||||
.Nx 1.3 .
|
||||
.Sh BUGS
|
||||
The
|
||||
.Nm
|
||||
program does not print the compression ratio when not using files.
|
||||
