Title: [TASK] Use bash instead of shell in bin/fig

In Ubuntu, `/bin/sh` is not symlinked to `/bin/bash` by default but to `/bin/dash` so some shell syntax doesn't work as expected and it complains with 'Bad substitution' message.

So I would recommend to use `/bin/bash` by for the existing fig script and all future scripts.
