What if bash scripting is your main language?

Then use bash scripts for everything. Good luck.

I would update my CV. Don't get me wrong, you can do a lot of good stuff in Bash. But if I want to do a lot of more complex processing, having a language with useful iteration constructs like Python, Ruby, Groovy or others needs to be an option that's on the table.
