Ah, forgot about that, thanks.
My xterms are 132 and 80 will cut off the arg I'm grepping for.

Thanks.  That mostly worked.
Did not work for Xorg process or xfwm process,
even though those strings show up in the px -awwo output.
Changing the selection to -awwo pid,comm,args picked them up.
I don't understand that...

Thanks.  Most of that cruft (bash -c) was added trying to get it to work.
I thought the second grep was needed to get rid of the grep invoking command,
but that's only when run from a terminal, not startx/.xinitrc.
Thanks.

Appreciate the extra info.
