If you are talking about ps auxww correct, but ps -auxww is valid
in SCO.  It's not documented, but an x used in an argument to ps
in SCO will give you an error in almost every way you try it
except in certain combinations and just placing it in a different
order will give an error.


IOW the x does nothing and you'lll get errors if you don't always
inlcude the 'u'.  A SWAG would make me thing the 'x' is treated
as 'user x'.   So that option string actually works but does the x
adds nothing as far as I can tell.

Try ps -leafxu  vs   ps -leafux.  In the beastie world users
are associated with U, and the -u has to do with the order things
are presented.
