Is there a way to output debug messages in Perl that are not piped? I have a Perl script that I use in a pipe but I really want to print some diagnostic information to the screen instead of to the pipe.

Are you piping both stdout and stderr? If not, write to the one you’re not piping 🙂
e.g.
(If you don’t provide a handle, STDOUT is the default of course – unless you’ve asked Perl to use a different default handle…)
