First and foremost, have you tried Getopt::Long yet? I've never experienced anything resembling pain using that module to handle my CL args.

Secondly, I'm sure there are a lot of monks here who use both Perl and Bash for doing simple tasks on a regular basis. I find that Bash syntax will be very limiting beyond doing simple things, though, and it is far less portable than Perl. Also, there's no such thing as bashmonks.org :)

In all seriousness, I doubt you'll find a task you can do in Bash that you can't do in Perl, but there's a lot of things you do in Perl that would be nearly impossible to do in Bash (alone).

Update: corrected type.
