The UseGetOpt.sh on the url above is very similar to the scripts in
"/etc/bash_completion.d" but I am not sure that it is entirely
applicable in your case; you will have to create specific scripts for
each expression in your file. You have to ensure that bash completion
is uncommented (I think that it is by default by I replace these files
without looking at them so I don't know) in .bashrc.
I have some custom ones for the initctl commands - start, stop,
restart, reload - so I can type, for example, "sto<tab> av<tab>"
instead of typing "sto<tab> avahi-daemon". So, AFAIK, it is only
useful if you have a two-word command. For one-word commands, you
should create aliases.
