Perhaps I'm missing some security implication here but I've always been

Do you really need to use newgrp(1) from util-linux?
The implementation from shadow-utils supports "sg" alias and the
option "-c".
sg <groupname> -c <command>
Thank you Karel. I've been missing that utility for years. I have to
question why it's a separate utility though. It seems to me that the
additional functionality would make a natural extension to newgrp. I
also don't understand why newgrp is not part of core-utils, especially
given that "su" is. It seems a shame to restrict sg to Linux. Adding to
the confusion, I've just noticed that shadow-utils includes its own
newgrp command and sg is simply a link to newgrp. In other words, do you
really need to include newgrp with util-linux? Perhaps you could simply
deprecate it and the distributions could start picking up the more
capable version via shaadow-utils.
For my application, I need a solution for Solaris and Linux; now I have
to figure out what it will take to port sg to Solaris.
Thank you,
Keith
