counting users?
Is it possible to count the number of users? or specifically emac users?

I know that you can count certain file sizes, like
find /usr/bin/ -size 11k -exec ls {} \;|wc -1

but how would I count users?

have a look at the output of the command "who".

Some combination of 'who' and/or 'ps' would probably help you.

ps -ef | grep emacs | wc -l

would catch every instance of emacs running, but it will also count users who are using emacs more than once.
