Why do people use 'cat' at every opportunity?  Maybe that's why
they sell so many multiprocessor machines? :-) :-)

Simpler:

	while read fie
	do
		something with $fie
	done <file

no additional processes.

I agree about sh vs csh.  But I won't get started in *that* religious
war.  Get ksh... the best of both worlds (hee hee)...
