That all depends on what you want to sort by.  For example, if you wanted
to sort by process names as the textual primary key, and process id as the
numeric secondary key, try:

ps -e | sort -k4,4 -k1,1n

How does that sorting solve determining which process you intended to kill?

Don't work too hard, make some time for fun as well!
