| 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
|
|---|
| 7 | mailing lists. It has resulted in at least one flame war in the recent past.
|
|---|
| 8 | To hopefully put an end to this once and for all, we here present two of
|
|---|
| 9 | the options for equipping your system with "which". The question of which "which"
|
|---|
| 10 | is for you to decide.</para>

|

| 20 | <para>The second option (for those who don't want to install the program)
|

| 21 | is to create a simple script:</para>
|

| 22 | <screen><userinput><command>cat > /usr/bin/which << "EOF"</command>
|

| 28 | <para>This should generally work OK and is probably the easiest solution
|

| 29 | for boxes which don't need a good user environment to work in.</para>
