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.ENV_SUPATH (string)
- -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:
- clears all the environment variables except for TERM
- initializes the environment variables HOME, SHELL, USER, LOGNAME, PATH
- changes to the target user's home directory
- sets argv 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:
- the shell specified with --shell
- the shell specified in the environment variable SHELL if the --preserve-environment option is used
- the shell listed in the passwd entry of the target user
- 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.
- 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.
