Since you added .bak to the -i option, you'll end up with both versions, so you will see it. If you're on a *nix system, you could leave of the .bak in which case you'll end up with just the one file. For some reason, adding the ext to keep the original is required on Windows (ActiveState Perl). -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
