I hate to nitpick, but all your examples should leave off the "dash"
(the '-' character): ps has been hacked so that it exhibits system V
behavior when provided options preceded by a dash, and bsd behavior
otherwise (but it also tries the bsd behavior when the system V option
you've provided don't make sense).

 $ ps -V
 procps version 2.0.7
 $ ps -x
 Bad syntax, perhaps a bogus '-'?

Otherwise a good post; I find 'ps fax' especially useful when I'm
trying to figure out which process needs killing.
