POSIX's "renice" has the syntax: renice -n increment [-g | -p | -u] ID ... unfortunately, util-linux's renice does not recognize the "-n", but only has: renice priority [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...] Expected: renice [-n] priority ... where the "-n" is optional. Note: That also matches coreutils's "nice" which takes an option "-n" argument.
