SYNOPSIS

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

DESCRIPTION

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
-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.
