It's not the pipe that's truncating the output, it's ps. Sounds like
it's a bug, because it should check if the output is to a terminal
and use that to decide the format of the output (c.f. ls). Try reporting
it at http://bugzilla.redhat.com

You can either force a wide column width:

	COLUMNS=1000 ps -ef | grep httpd

or you can just use sane BSD ps syntax:

	ps auxww | grep httpd

Just as an aside... if you're thinking of doing this from within a script,
don't! Grepping the process table is an unreliable method for finding out
pretty much anything, and there are better alternatives available.
