Hi,
Well, with that grep, @files will end up containing only ones, and you'll not even be able to sort out exactly 'which' files where there...

Cheers

    Actually, no - that would happen if I were using map. grep doesn't return the value of the expression, it returns the original element if the expression evaluates to true. Observe:
    $ touch a b e ; perl -le'@f=grep -e, qw(a b c d e f); print "@f"' a b e
