My experience with anything involving tcl/tk has always been suboptimal. Also, we're specifically talking about shell scripts. I'd argue that if you're implementing an entire protocol into a shell script, yes, you should consider more efficient languages. If you're just dumping data into a pipe like you would to std out, sure that's fine. The key here, at least for me, is complexity. Are you bludgeoning shell scripts into something it wasn't meant for? Is there a better alternative meant to do the thing you're doing?
