[ILUG] Limits of grep?

That's a shell issue as much as grep. Try find . -print | xargs grep
"pattern"

xargs takes a list of files on stdin and passes as many as possible to
the command you've chosen to execute. It will run multiple grep
processes sequentially until it has run out of parameters to run it
with.

If you've got an SMP box, xargs will help you parallelize the task with
xargs -P 2 grep "pattern". Probably not much of a win on an I/O
intensive grep though.

Paul.
