<title>Installation of Gzip</title>

<para>Prepare Gzip for compilation:</para>

<screen><userinput>./configure --prefix=/usr</userinput></screen>

<para>The <userinput>gzexe</userinput> script has the location of the
<userinput>gzip</userinput> binary hard-wired into it. Because we later change
the location of the binary, the following command assures that the new
location gets placed into the script:</para>

<screen><userinput>cp gzexe.in{,.backup}
sed 's%"BINDIR"%/bin%' gzexe.in.backup &gt; gzexe.in</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>Install the package:</para>

<screen><userinput>make install</userinput></screen>

<para>And move the programs to the <filename
class="directory">/bin</filename> directory:</para>

<screen><userinput>mv /usr/bin/gzip /bin
rm /usr/bin/{gunzip,zcat}
ln -s gzip /bin/gunzip
ln -s gzip /bin/zcat
ln -s gunzip /bin/uncompress</userinput></screen>
