Done. Feedback welcome.

TL;DR:

There's a script that will help with that (for users that don't know how):

* checks for ./occ, prompts user for path if not found
   * path input supports tab-completion
* determines web server user name from (www-data|httpd|nobody)
   * Did I miss any?
* checks for existing alias
* creates alias string, offers to run it
* determines user's name
* checks for occ alias in user's .bash_aliases
* offers to add if if missing
* checks for SUDO_USER's .bash_aliases having occ alias
* offers to add it if missing
* verifies that owner of occ is web server user

occ -[TAB] will auto-complete all the "switches" that start with hyphen(s)
occ [TAB] will show all the commands up to and including the first ":"
occ $some_command:[TAB] will show all subcommands following initial colon


Was interesting - there were >180 commands & subcommands initially; had
to figure out a way to narrow it down to something easier to use.

I think it works rather well now.


Also, the completion script adds colour to the completions' matching
portions.

Again, feedback welcome!


Also, sorry for the long reply, I used this as a basis for a README.md...
