Your favourite UNIX pipe ?

[Andreas Lampen]

Please send me your most favourite (sophisticated, cryptic, funny) pipe !

I want to open the list with a quite common one:
  soelim foo.ms | refer -sAD -l4,2 | pic | troff -Talw -ms | tps | lpr -Plw

and a cross machine pipe:
  tar cf - | dd bs=20k | rsh coma "cd blubber; dd bs=20k | tar xf -"

We are currently working on a concept for an object oriented shell for
UNIX and (of course) ran into difficulties when trying to model the
pipe mechanism. We came up with a first idea but soon found an example
where this didn't work ... .

Now, this inquiry shall set up a list of pipes that helps us to validate
our ideas. Additionally, I think such a list will be quite interesting
for UNIX users. I will post a summary anyway.

Thanks in advance,
		   Andy
