in thread Regex To Remove File Extension

You're assuming too much, your regex will fail on:
index.html foo.pl CGI.pm video.mpeg foo.pl~
and you'll get a bad result with *nix dotfiles
.foo .bar

Focus on the requirements - 1) A file must contain an extension 2) the extension is everything following the final dot

my @names = qw/ index.html foo.pl CGI.pm video.mpeg foo.pl~ .bash_hist +ory .bash_rc /; foreach my $string ( @names ) { print "$string -> "; $string =~ s/(.+)\.[^.]+$/$1/; print "$string\n"; }
grep
One dead unjugged rabbit fish later...

    Yours is a much better solution than my simple one.

    Although my solution works for the example given, it does assume that all filenames are of the format provided in the original post and does not take into consideration the examples you provided.

    Thanks for the feedback and great sample code!
