Hi everyone,

First off, thanks for the great tool, and thanks to anyone who takes the time to read this.

This is sort of a followup on my previous email, but I was wondering if anybody uses org-babel with bash in session mode? I've found it to be pretty buggy for all but simple tasks, and I was wondering if I'm doing something wrong. My googling hasn't lead to many hits, so I suspect that might be the case. The previous email (below) is just one example, but generally I've had problems when using multiline commands (e.g. loops, declaring functions, etc).

Thanks
Steve
