tcsh

It was default on OS X when its first version came out.

It's not 'standard' for most *nix systems, and lacks some features of bash, but it has this M-p trick where you can auto-complete commands up to the point where you've typed. I really like it and it's ingrained in me. bash has something like it but it's not the same. I think it requires an extra keystroke or something. Also I've built a bunch of this and that to work with it that I rely on, and it lets me have a right prompt with seconds ☺.

I still usually script in sh/bash. There are some instances where scripting in tcsh is required, but that's not supposed to be the best, so given the warnings I try to avoid it unless super necessary.
