Yes, but this may or may not be suitable for whatever you're doing.  As
an example, this would take stdin and pipe it to tr.

#!/bin/sh

cat | tar [A-Z] [a-z]


There are probably better ways (which I'd also be interested in
knowing).  :)

Fwiw, you could use "exec cat" instead of "cat" if you needed the shell
to persist after the cat invocation, but that's a different story.

Maybe if you posted what you're trying to do, some better ways of doing
it might come to light?

HTH.
