Prints just the name of all currently running process and is piped to the less command to control the output.

Code:
ps axf  | awk '{print "PROC -> "$5}' | awk '!x[$0]++' | less

Thats a parsed ps axf command. It lists running processes. A better command is top or htop. It runs in real time. Try it.

if you want to list processes entirely
ps axf -eo pid,ppid,sid,uid,args

give pstree a try too.
