If your friend is worried about SingleUnixSpec V2, he should read
this quote from the description of newgrp in that specification:
The newgrp command is intended only for use from an
interactive terminal. It does not offer a useful
interface for the support of applications.
The exit status of newgrp is generally inapplicable.
If newgrp is used in a script, in most cases it will
successfully invoke a new shell and the rest of the
original shell script will be bypassed when the new
shell exits.
So while it might be debated whether FreeBSD should have any
newgrp command at all, the specification makes it clear that
your friend should not be using it in any script.
Thus, tell your friend to change his scripts, "in order to
comply with SUSv2".
