In case you're not, here are some "Bashisms" that really suck to be without:
* built-in regex support (e.g. `[[ $var =~ ^1\.2\.[34]$ ]]`)
* process substitution (e.g. `diff <(before_command) <(after_command)`) and all sorts of other redirection tricks
* indexed and associative arrays
Some of this can be worked around by shelling off to grep for regular expression matching or awk for arrays, but Bash makes things so much cleaner and maintainable.
