<title>which-&which-version; and alternatives</title>

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

&which-intro;
|

&which-inst;
|

&which-desc;
|

|
|
<sect2><title>The 'which' script</title>
|
|
<para>The second option (for those who don't want to install the program)
|
|
is to create a simple script:</para>
|
|
<screen><userinput><command>cat > /usr/bin/which << "EOF"</command>
|
|
#!/bin/bash
|
|
type -p "$@"
|
|
<command>EOF
|
|
chmod 755 /usr/bin/which
|
|
chown root:root /usr/bin/which</command></userinput></screen>
|
|
<para>This should generally work OK and is probably the easiest solution
|
|
for boxes which don't need a good user environment to work in.</para>
