The only time I use shell is if I expect a pure list of commands with no loops or significant logic. Actually, I'm not sure I've ever done a loop in bash at all. The few times I've tried to write even trivial programs in bash resulted in me eventually encountering something ugly and unpleasant, then quitting and starting over in Python, and having a working solution extremely fast.
