grep over the normal U*x grep. It has a few cool extensions over the POSIX grep. One of them is the -R option that lets you recurse through directories to search for a pattern. That's one of the reasons I've always compiled the GNU grep on U*x machines as well. If there's no option but to use the standard grep, all isn't lost - xargs and find along with grepdo the same job. i.e. find -type f -print| xargs grep -li "pattern"It's no fun having three processes to do something instead of merely one, but that's the only option when in a bind.
