RUNUSER(1)			 User Commands			    RUNUSER(1)

NAME
       runuser - run a shell with substitute user and group IDs

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

DESCRIPTION
       Change  the  effective user id and group id to that of USER.  Only ses‐
       sion 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

       -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

       --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.
