|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
utility is a minimal implementation of the
|
1998-01-05 07:14:54 +00:00
|
|
|
.Xr gzip 1
|
2004-07-02 22:22:35 +00:00
|
|
|
utility.
|
|
|
|
|
It supports
|
1997-12-13 09:57:48 +00:00
|
|
|
compression and decompression of individual files, as well as
|
|
|
|
|
streaming compression and decompression via standard input and
|
|
|
|
|
output.
|
|
|

|
|
|
The default operation is compression, decompression can be
|
1997-12-13 09:57:48 +00:00
|
|
|
selected by supplying the
|
|
|
|
|
.Fl d
|
|
|
|
|
flag on the commandline.
|
|
|
|
|
.Pp
|
|
|
|
|
If any
|
|
|
|
|
.Ar file
|
2001-07-15 08:06:20 +00:00
|
|
|
arguments are supplied, the operation is performed on each file
|
2004-07-02 22:22:35 +00:00
|
|
|
separately.
|
|
|
|
|
Compression replaces the original file with one having a
|
1997-12-13 09:57:48 +00:00
|
|
|
.Pa .gz
|
2004-07-02 22:22:35 +00:00
|
|
|
suffix.
|
|
|
|
|
Decompression will remove a
|
1997-12-13 09:57:48 +00:00
|
|
|
.Pa .gz
|
|
|
|
|
suffix if one is present.

If no

arguments are supplied,
|
|
|
|
|
.Nm

|
reads from standard input and writes the results of the operation
|
1997-12-13 09:57:48 +00:00
|
|
|
to standard output.
