</para>
</sect2>
<sect2><title>Description</title>
<sect3><title>gunzip</title>
<para>
gunzip decompresses files that are compressed with gzip.
</para>
</sect3>
<sect3><title>gzexe</title>
<para>
gzexe allows to compress executables in place and have them
automatically uncompress and execute when they are run (at a penalty in
performance).
</para>
</sect3>
<sect3><title>gzip</title>
<para>
gzip reduces the size of the named files using Lempel-Ziv coding (LZ77).
</para>
</sect3>
<sect3><title>zcat</title>
<para>
zcat uncompresses either a list of files on the command line or its
standard input and writes the uncompressed data on standard output
</para>
</sect3>
<sect3><title>zcmp</title>
<para>
zcmp invokes the cmp program on compressed files.
</para>
</sect3>
<sect3><title>zdiff</title>
<para>
zdiff invokes the diff program on compressed files.
</para>
</sect3>
<sect3><title>zforce</title>
<para>
zforce forces a .gz extension on all gzip files so that gzip will not
compress them twice. This can be useful for files with names truncated
after a file transfer.
</para>
</sect3>
<sect3><title>zgrep</title>
<para>
zgrep invokes the grep program on compressed files.
</para>
</sect3>
<sect3><title>zmore</title>
<para>

files one screen at a time on a soft-copy terminal (similar to the
more program).
</para>
</sect3>
<sect3><title>znew</title>
<para>
Znew re-compresses files from .Z (compress) format to .gz (gzip) format.
</para>
