Oh, right. I can do:

	for i in `generate a list of file names`
	do
		...
	done

too. But what if thise file names are generated by:

	find / -type f -print

Just how much stuff can *you* put in command substitutions?

To do this under csh, I basically have to do something like:

cat > foo << 'EOF'
#
do_something_with_$*
EOF
find ... | xargs csh foo
