ps auxw will do so. If that isn't enough, try 'ps auxewwwwww'

This wins an award for 'Pointless use of cat'. Preferred:
% grep iTunes ps_output
% grep iTunes < ps_output
Or don't bother with the intermediate file at all:
% ps auxw | grep 'i[T]unes'
(Yes, the  are intentional, and experienced Unix/Linux users know why :)
(As an added bonus, on some systems /bin/ps will notice that it's going to a pipe, and automagically disable the 'trim to terminal width' code for you, totally obviating the issue. A quick check shows Linux does, Solaris and an older AIX box don't.)

No scenario that hasn't been there for literally a quarter of a century already, the 'w' flag was added *decades* ago for basically this reason....
