automatically uncompress and execute when they are run (at a penalty in 
performance).</para></sect3>

<para>gzip reduces the size of the named files using 
Lempel-Ziv coding (LZ77).</para></sect3>

<sect3><title>zcat</title>

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>
