how do i get the number of users on the system? It should probably be in the proc fs somewhere but I don't know where to look.

This is for part of a fair-share scheduler.

who | wc -l

That's the current number login sessions. You could do who | awk '{print $1; }' | sort | uniq to get the number of unique usernames logged in at the time.

Or you could do wc -l /etc/passwd to get the number of users set up in the passwd file.
