I grabbed the following little pipe off the net some time ago:

    find dir <selection criteria> -print | perl -n -e 'chop;unlink;'

I thought, sort of by extension, that the following would work:

    find dir <selection criteria> -print | perl -n -e 'chop;chmod 044;'

but the modes of the selected files aren't changed. Why? (In case you hadn't
guessed, I'm a Perl novice.) No errors are printed either, so what I've
typed is presumably legal Perl-ese.
