The su --help give this messages:
Usage: su [OPTION]... [-] [USER [ARG]...]
Change the effective user id and group id to that of USER.
-, -l, --login make the shell a login shell
-g --group=group specify the primary group
-G --supp-group=group specify a supplemental group
-c, --commmand=COMMAND pass a single COMMAND to the shell with -c
--session-command=COMMAND pass a single COMMAND to the shell with -c
and do not create a new session
-f, --fast pass -f to the shell (for csh or tcsh)
-m, --preserve-environment do not reset environment variables
-p same as -m
-s, --shell=SHELL run SHELL if /etc/shells allows it
--help display this help and exit
--version output version information and exit
A mere - implies -l. If USER not given, assume root.
but when try to run su with '--group', it says:
su: unrecognized option `--group'
Try `su --help' for more information.
