There's always the ever-handy 'which' command, but this doesn't exist on
most LRP/LEAF distributions. I've added which to busybox in the Dachstein
CD release (it will be in the floppy Dachstein releases, as soon as I get
around to burning another image).
You can also use the 'type' shell built-in to look for programs, but it's
output isn't in as convinent a form as the output of 'which' (which
convinently returns nothing if the program is not found). Of course, you
could always cheat and make your own which from type and shell-script:
#!/bin/sh
x="`type $1`"
case "$x" in
*builtin) ;;
*"not found") ;;
*)
set -- $x
eval echo \${$#}
;;
esac
