	Seems like this takes fewer keystrokes...  I don't know
	much awsk, but is there a way of feeding awk a cmd if
	the cont returns true?  Say:

	cmd1 | awk '{print $9}' == 'foo.c' 
	then
		echo "Found foo.c"
		mv foo.c ~/C_file
	END


	it's mostly like a perl hack, tho.

	anyway, thanks, gents,

	gary
