comm '! sort file1' '! sort file2'

[Arthur David Olson]

I regularly want to run "comm" on a pair of unsorted files.  So I ended up
writing a shell script to do the job, the guts of which (simplified for the
purposes of this article) is:

	tmp=/tmp/\#scomm.$$
	sort "$1" > $tmp
	sort "$2" | comm $tmp -
	rm $tmp

All fine and dandy.  But then I got to thinking. . .that what I'd *really*
like to be able to do is use a command like

	comm '! sort file1' '! sort file2'

(where the space after the '!' should be your clue that I use csh) and have
comm do the dirty work.

And then I got to thinking. . .that if fopen turned
	fopen("!whatever", "r")
calls into
	popen("whatever", "r")
calls (with other changes as necessary), then what I'd like to see happen
with the "comm" command would happen generally.
