| I'm using it to find out where an executable lives. Useful if your system
| has several versions, and which you execute depends on how your PATH is
| ordered. And since I *can't* execute wall(1) (or finger(1)) on that
| machine, locating it tells me why - it's not that it's not there, just
| that it's not world executable. By extension, I have an $ETC variable I
| can also search for the occaisional command that's not normally in my
| $PATH, like ping(1).

I like bash's type -all feature, where you can find all occurances of
a command in the PATH.
