I already knew at that point that the script wasn't executed at all because if ti did the carp module would produce a perl error. As for the shebang line i though you were refering to '#!/usr/bin/perl' which i did had correctly at my script in terms of existence and correct apth. I had no idea that before that is hould had a line '#!' before the shebang line, which io just tried and didn't work for me.
