<para>The presence or absence of the <command>which</command> program
|
|
in the main LFS book is probably one of the most contentious issues on the
|
|
mailing lists. It has resulted in at least one flame war in the past. To hopefully
|
|
put an end to this once and for all, presented here are two options for equipping
|
|
your system with <command>which</command>. The question of which
|
|
<quote><command>which</command></quote> is for you to decide.</para>
|
|
|
|
<para>The first option is to install the actual GNU
|
|
<application>which</application> package.</para>

is to create a simple script (execute as the
