I've been trying to pay attention but I don't know if this has
come up before.  Anyway -

How about perl having some sort of built-in directory tree walking?
(Or a perl library routine for this.) Something like the ftw() routine
that many versions of Unix have, that lets you walk through a directory
tree and call a specified function for each thing in the tree.

I know I could open a pipe from "find ... -print" but I find it to be
a pain trying to deal with the different find options on different
machines.  Some machines have -xdev, some have -mount, some have -prune
and so on.  It would be great if perl had some sort of tree-walking
built in.  Then I could make fancier selections than what 'find' lets me do.

Just a thought.  Perl is great.  Thank you Larry.
Steve
