RUNUSER(1)							   User Commands							RUNUSER(1)

NAME
runuser - run a command with substitute user and group ID SYNOPSIS
runuser [options] -u user [[--] command [argument...]] runuser [options] [-] [user [argument...]] DESCRIPTION
runuser allows to run commands with a substitute user and group ID. If the option -u is not given, it falls back to su-compatible seman- tics and a shell is executed. The difference between the commands runuser and su is that runuser does not ask for a password (because it may be executed by the root user only) and it uses a different PAM configuration. The command runuser does not have to be installed with set-user-ID permissions. If the PAM session is not required then recommended solution is to use setpriv(1) command. When called without arguments, runuser defaults to running an interactive shell as root. For backward compatibility, runuser defaults to not change the current directory and to only set the environment variables HOME and SHELL (plus USER and LOGNAME if the target user is not root). This version of runuser uses PAM for session management. OPTIONS
-c, --command=command Pass command to the shell with the -c option. -f, --fast Pass -f to the shell, which may or may not be useful depending on the shell. -g, --group=group The primary group to be used. This option is allowed for the root user only. -G, --supp-group=group Specify a supplemental group. This option is available to the root user only. The first specified supplementary group is also used as a primary group if the option --group is unspecified. -, -l, --login Start the shell as a login shell with an environment similar to a real login: o clears all the environment variables except for TERM o initializes the environment variables HOME, SHELL, USER, LOGNAME, PATH o changes to the target user's home directory o sets argv[0] of the shell to '-' in order to make the shell a login shell -m, -p, --preserve-environment Preserve the entire environment, i.e. it does not set HOME, SHELL, USER nor LOGNAME. The option is ignored if the option --login is specified. -s, --shell=shell Run the specified shell instead of the default. The shell to run is selected according to the following rules, in order: o the shell specified with --shell o the shell specified in the environment variable SHELL if the --preserve-environment option is used o the shell listed in the passwd entry of the target user o /bin/sh If the target user has a restricted shell (i.e. not listed in /etc/shells) the --shell option and the SHELL environment variables are ignored unless the calling user is root. --session-command=command Same as -c , but do not create a new session. (Discouraged.) -V, --version Display version information and exit. -h, --help Display help text and exit. CONFIG FILES
runuser reads the /etc/default/runuser and /etc/login.defs configuration files. The following configuration items are relevant for runuser: ENV_PATH (string) Defines the PATH environment variable for a regular user. The default value is /usr/local/bin:/bin:/usr/bin. ENV_ROOTPATH (string) ENV_SUPATH (string) Defines the PATH environment variable for root. The default value is /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin. ALWAYS_SET_PATH (boolean) If set to yes and --login and --preserve-environment were not specified runuser initializes PATH. EXIT STATUS
runuser normally returns the exit status of the command it executed. If the command was killed by a signal, runuser returns the number of the signal plus 128. Exit status generated by runuser itself: 1 Generic error before executing the requested command 126 The requested command could not be executed 127 The requested command was not found FILES
/etc/pam.d/runuser default PAM configuration file /etc/pam.d/runuser-l PAM configuration file if --login is specified /etc/default/runuser runuser specific logindef config file /etc/login.defs global logindef config file SEE ALSO
setpriv(1), su(1), login.defs(5), shells(5), pam(8) HISTORY
