perl doesn't do any such thing. In a *nix shell environment, when the file is being executed without calling the perl interpreter, the shell interprets the line and execute it. If the script is run with "perl foo.pl" then the shebang is ignored, as the perl interpreter ignores it as a comment. I believe a Windows environment also ignores it. -- Erez La perfection soit atteinte non quand il n'ya plus rien à ajouter, mais quand il n'ya plus rien à retrancher. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
