One can get the gid via ps -G gid under Linux, DEC and Solaris:

>From the dec ps man page:

  -G glist
        Writes information for processes whose real group ID numbers or names
        are given in glist.  The glist is a list of process-group identifiers
        enclosed in " " (double quotes) and separated from one another by a
        comma or one or more spaces (or tabs), or both.  Because of the way the
        shell treats spaces and tabs, you need to quote space-separated lists.

I can't find a switch under FreeBSD.

That is all of the systems that I have access to.
