In my humble personal opinion, I try to avoid bash scripts longer than a couple lines because I find the syntax so obtuse and unintuitive it's difficult to maintain and write less buggy code. But that is mostly a reflection of my personal inexperience. I think the only time a bash script is really needed is for maximum portability in systems _with bash_. (I would use python for a wrapper in personal projects, given python comes pre-installed on many linux systems and OS X, but I completely understand not wanting to burden Windows users with an extra python dependency to install.)
