5<para>The presence / absence of the which program in the main <acronym>LFS
6</acronym> book is probably one of the most contentious issues we have on the
7mailing lists. It has resulted in at least one flame war in the recent past.
8To hopefully put an end to this once and for all, we here present two of
9the options for equipping your system with "which".</para>

19<para>The second option (for those who don't want to install the program)
20is to create a simple script:</para>
21<screen><userinput><command>cat &gt; /usr/bin/which &lt;&lt; "EOF"</command>
22#!/bin/bash
23type -p "$@"
24<command>EOF
25chmod 755 /usr/bin/which
26chown root:root /usr/bin/which</command></userinput></screen>
27<para>This should generally work OK and is probably the easiest solution
28for boxes which don't need a good user environment to work in.</para>
