users does what is requested. From the man page:

users lists the login names of the users currently on the system, in sorted order, space separated, on a single line.

Try this:

w -h  | cut -d' ' -f1 | sort | uniq

The w -h displays all users in system, without header and some output. The cut part removes all other information without username. uniq ignores duplicate lines.

$ ps xau | cut -f1 -d " "| sort | uniq | tail -n +2

You may want to weed out names starting with _ as well like so :

ps xau | cut -f1 -d " "| sort | uniq | grep -v ^_ | tail -n +2
