surfraw-update-path - updates PATH in shell config files SYNOPSIS
surfraw-update-path [-add] [-remove] [-check] [-sys] [-all] [-help] [-shell=SHELL] DESCRIPTION
surfraw-update-path adds the surfraw elvi directory (/usr/lib/surfraw) to your PATH in your shell's config file. Currently it supports bash, sh, csh, tcsh, ash, dash, ksh, pdksh, zsh, rc, and es Don't forget to login again or source your login files for it to take effect. OPTIONS
-check Checks to see if the surfraw config code is present. This is the default. -add Adds the surfraw config code. -remove Removes the surfraw config code -sys Updates the system-wide shell config instead of the user. Must be done as root. -shell=SHELL Selects the shell to configure. Defaults to the value of the $SHELL environment variable. Currently supported shells are: sh, ash, bash, dash, csh, tcsh, ksh, pdksh, zsh, rc, and es. -all Attempts to configure the startup files for all known shells -help Gives a usage message RETURN VALUE
-check returns 0 if the surfraw code is present in the file, 1 if it is not found, or 2 on error. All other options return 0 on success, or 2 on error. ENVIRONMENT
SHELL Used to determine which shell to configure, if -shell is not given. HOME Used to find users config files. ENV Used by posix-compliant shells to specify a startup rc file. ZDOTDIR Used to find user config files for zsh. If not set, defaults to HOME. SEE ALSO

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 substitute user and group ID. If the option -u not given, fallback to su compatible semantic and shell is executed. The difference between the commands runuser and su is that runuser does not ask for password (because it may be executed by 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=command Pass command to the shell with the -c option. --session-command=command Same as -c but do not create a new session (discouraged). -f, --fast Pass -f to the shell which may or may not be useful depending on the shell. -g, --group=group specify the primary group, this option is allowed for root user only -G, --supp-group=group specify a supplemental group, this option is allowed for root user only -, -l, --login Starts the shell as login shell with an environment similar to a real login: o clears all 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 Preserves the whole environment, ie does not set HOME, SHELL, USER nor LOGNAME. The option is ignored if the option --login is specified. -s SHELL, --shell=SHELL Runs 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. --help Display help text and exit. --version Display version information 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 could was not found FILES
