This is the command runuser that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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 semantics 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 suid permissions.
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
A supplemental group to be used. This option is allowed for the root user only.
-, -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
Use runuser online using onworks.net services
