Only through zsh did I find out about tab auto-complete.

When I used bash, whenever I needed to uncompress a tarball I downloaded, I would type in the full, ~50 character filename. Only through zsh did I find out about tab autocomplete, and when I had to use bash on a friend's Mac, to my surprise, autocomplete worked.

I still use zsh, though.

For a while bash autocomplete was around, but you had to know to source it from /etc, which seems dumb. Now this stuff is sourced automatically[1].

[1] And sometimes they use it as a 'cheat.' virtualenvwrapper (on Ubuntu, and I assume Debain) is dropped into /etc/bash_completion.d/ instead of somewhere in $PATH. Meaning that it's auto-sourced for bash users, but zsh users need to know where it is, and source it. It seems stupid to put it in the bash_completion directory. Sure it has some completion stuff in it, but the bulk (and purpose) of the file is to setup a bunch of wrapper shell functions. It's like they didn't have a formal place to put it so they just jammed it somewhere.
