I was referring to the mess over "tail -n 30", "tail -30", "tail +30" etc. and more specifically was trying to indicate that I didn't think "timeout -0" would be a useful direction, for that reason.

Well my reasoning for having "0" mean don't timeout, was to have an easy way in scripts to specify no timeout, like: timeout=0 # none [ "$platform" = "buggy" ] && timeout=10 timeout $timeout command I'm unsure whether to make this change. If we do I guess `timeout` should immediately exit(124). This change in behavior would need a mention in NEWS anyway. cheers, Pádraig.
