.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility is a minimal implementation of the
|
|
.Xr gzip 1
|
|
utility.
|
|
It supports
|
|
compression and decompression of individual files, as well as
|
|
streaming compression and decompression via standard input and
|
|
output.
|
|
.Pp
|
|
The default operation is compression, decompression can be
|
|
selected by supplying the
|
|
.Fl d
|
|
flag on the command line.
|
|
.Pp
|
|
If any
|
|
.Ar file
|
|
arguments are supplied, the operation is performed on each file
|
|
separately.
|
|
Compression replaces the original file with one having a
|
|
.Pa .gz
|
|
suffix.
|
|
Decompression will remove a
|
|
.Pa .gz
|
|
suffix if one is present.
|
|
.Pp
|
|
If no
|
|
.Ar file
|
|
arguments are supplied,
|
|
.Nm
|
|
reads from standard input and writes the results of the operation
|
|
to standard output.
|
|
.Pp
|
|
If the
|
|
.Fl c
|
|
option is specified,
|
|
.Nm
|
|
writes the results to standard output and keep the original files
|
|
unchanged.
