You should bear in mind that that will probably be a GNU "ps" specific option.  
On Fedora you're fine; on other UNIX platforms that may not be available.

I'm quite fond of "ps axf"; it is easy to type and informative, and shows the 
parent-child stuff visually in the listing, very nice. It (the "f" option) is 
also GNU ps specific.
