You will get people who decry bashisms that pollute the bourne shell. IMO they often make things safer so I want them - like [[ ]] which works so much more expectedly than [ ]. Shells are good at starting, stopping, backgrounding processes and piping, redirecting and substituting output that they make programming languages feel very clunky imo. Plus you can now almost expect bash to always be installed on a machine somewhere.
