Chip, you just typed ten lines of perl, including a few hundred
characters, to achieve basically the same effect as

  $ ls -F `echo $PATH | tr : '\012'` | sed -n 's/\*$//p' | sort | uniq -d

or, in csh,

  % ls -F $path | sed -n 's/\*$//p' | sort | uniq -d

Are you sure you're spending your programming time wisely?
