		An equally important but opposite problem with pipes getting stuck is pipes getting broken because some commands at the front of the pipe expects buffering down the pipe. Some years ago I was scratching my head trying to figure out why `curl ... \| grep -q` was giving me a "Failed write body error". I knew "grep -q" would close stdin and exit as soon as a match is found, and therefore I needed a buffer in front of grep but I was on a Mac, which to this day still doesn't come with "sponge" (or stdbuf and unbuffer for that matter), so I had to find a cross-platform command that does a little buffering but not too much, and could handle stdout being closed. So I settled on: `curl ... \| uniq \| grep -q` To this day people are still confused why there's not a "sort" in front of uniq and the comment about this cross-platform buffer thing I put in the script.
