<para>The Findutils package contains programs to find files. Processes
are provided to recursively search through a directory tree and to
create, maintain and search a database (often faster than the recursive
find, but unreliable if the database has not been recently updated).</para>

<title>Installation of Findutils</title>

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

<screen><userinput>./configure --prefix=/usr --libexecdir=/usr/lib/locate \
    --localstatedir=/var/lib/locate</userinput></screen>

<para>The localstatedir directive above changes the location of the locate
database to be in /var/lib/locate, which is FHS-compliant.</para>

<para>Compile the package:</para>

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

<para>To test the results, issue:
<userinput>make check</userinput>.</para>

<para>Now install the package:</para>

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