RUNUSER(1)                       User Commands                      RUNUSER(1)

       runuser - run a shell with substitute user and group IDs

       runuser [OPTION]... [-] [USER [ARG]...]

       Change  the  effective  user  id and group id to that of USER.  Only session PAM hooks are run, and there is no
       password prompt.  This command is useful only when run as the root user.  If run as  a  non-root  user  without
       privilege  to  set user ID, the command will fail as the binary is not setuid.  As runuser doesn't run auth and
       account PAM hooks, it runs with lower overhead than su.

       -, -l, --login
              make the shell a login shell, uses runuser-l PAM file instead of default one, clears all envvars  except
              for TERM, initializes HOME, SHELL, USER, LOGNAME and PATH

       -g --group=group
              specify the primary group

       -G --supp-group=group
              specify a supplemental group

       -c, --command=COMMAND
              pass a single COMMAND to the shell with -c

              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 HOME, SHELL, USER, LOGNAME environment variables

       -p     same as -m

       -s, --shell=SHELL
              run SHELL if /etc/shells allows it

       --help display this help and exit

              output version information and exit

       A mere - implies -l.   If USER not given, assume root.
