Why not use which

which perl

it returns the path to perl in your environment.

 In the context of the brief code segment, why not replace it with:
 
 for dir in `echo $PATH | sed -e 's/:/ /g'`
 do
 	for cmd in perl5 perl
 	do
 
 This would find the first occurance in your path of either perl5 or
 perl,
 v. "first, find perl5, then (if needed) find perl, in your path".
