The situation of "oh no, fork XYZ added essentially the same functionality too...but with other option letters, and they count fields from 0, not from 1... and they used OUR option letter for something entirely different! ARGH" is irritatingly repeating itself, as if we never learn.
Real example:
su [-lp] [-u UID] [-g GID,...] [-s SHELL] [-c CMD] [USER [COMMAND...]] -u Switch to UID instead of USER -g Switch to GID (only root allowed, can be comma separated list)
util-linux has no -u UID. util-linux has -g, but it's not -g GID. Instead, it's -g GROUPNAME, it does not accept comma list of groups, and it sets only primary group. util-linux has -G GROUP for setting supplementary group ids, and to set more than one of them, they use -G GRP1 -G GRP2 style.
