NAME

       loginctl - Control the systemd login manager

SYNOPSIS

       loginctl [OPTIONS...] {COMMAND} [NAME...]

DESCRIPTION

       loginctl may be used to introspect and control the state of the systemd(1) login manager systemd-logind.service(8).

OPTIONS

       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

       -p, --property=
	   When showing session/user/seat properties, limit display to certain properties as specified as argument. If not specified, all set
	   properties are shown. The argument should be a property name, such as "Sessions". If specified more than once, all properties with the
	   specified names are shown.

       -a, --all
	   When showing session/user/seat properties, show all properties regardless of whether they are set or not.

       -l, --full
	   Do not ellipsize process tree entries.

       --no-pager
	   Do not pipe output into a pager.

       --no-ask-password
	   Do not query the user for authentication for privileged operations.

       --kill-who=
	   When used with kill-session, choose which processes to kill. Must be one of leader, or all to select whether to kill only the leader
	   process of the session or all processes of the session. If omitted, defaults to all.

       -s, --signal=
	   When used with kill-session or kill-user, choose which signal to send to selected processes. Must be one of the well known signal
	   specifiers, such as SIGTERM, SIGINT or SIGSTOP. If omitted, defaults to SIGTERM.

       -H, --host
	   Execute operation remotely. Specify a hostname, or username and hostname separated by "@", to connect to. This will use SSH to talk to
	   the remote login manager instance.

       -P, --privileged
	   Acquire privileges via PolicyKit before executing the operation.

       The following commands are understood:

       list-sessions
	   List current sessions.

       session-status [ID...]
	   Show terse runtime status information about one or more sessions. This function is intended to generate human-readable output. If you
	   are looking for computer-parsable output, use show-session instead.

       show-session [ID...]
	   Show properties of one or more sessions or the manager itself. If no argument is specified, properties of the manager will be shown. If
	   a session ID is specified, properties of the session are shown. By default, empty properties are suppressed. Use --all to show those
	   too. To select specific properties to show, use --property=. This command is intended to be used whenever computer-parsable output is
	   required. Use session-status if you are looking for formatted human-readable output.

       activate [ID...]
	   Activate one or more sessions. This brings one or more sessions into the foreground, if another session is currently in the foreground
	   on the respective seat.

       lock-session [ID...], unlock-session [ID...]
	   Activates/deactivates the screen lock on one or more sessions, if the session supports it.

       lock-sessions, unlock-sessions
	   Activates/deactivates the screen lock on all current sessions supporting it.

       terminate-session [ID...]
	   Terminates a session. This kills all processes of the session and deallocates all resources attached to the session.

       kill-session [ID...]
	   Send a signal to one or more processes of the session. Use --kill-who= to select which process to kill. Use --signal= to select the
	   signal to send.

       list-users
	   List currently logged in users.

       user-status [USER...]
	   Show terse runtime status information about one or more logged in users. This function is intended to generate human-readable output.
	   If you are looking for computer-parsable output, use show-user instead. Users may be specified by their usernames or numeric user IDs.

       show-user [USER...]
	   Show properties of one or more users or the manager itself. If no argument is specified, properties of the manager will be shown. If a
	   user is specified, properties of the user are shown. By default, empty properties are suppressed. Use --all to show those too. To
	   select specific properties to show, use --property=. This command is intended to be used whenever computer-parsable output is required.
	   Use user-status if you are looking for formatted human-readable output.

       enable-linger [USER...], disable-linger [USER...]
	   Enable/disable user lingering for one or more users. If enabled for a specific user, a user manager is spawned for him/her at boot and
	   kept around after logouts. This allows users who are not logged in to run long-running services.

       terminate-user [USER...]
	   Terminates all sessions of a user. This kills all processes of all sessions of the user and deallocates all runtime resources attached
	   to the user.

       kill-user [USER...]
	   Send a signal to all processes of a user. Use --signal= to select the signal to send.

       list-seats
	   List currently available seats on the local system.

       seat-status [NAME...]
	   Show terse runtime status information about one or more seats. This function is intended to generate human-readable output. If you are
	   looking for computer-parsable output, use show-seat instead.

       show-seat [NAME...]
	   Show properties of one or more seats or the manager itself. If no argument is specified, properties of the manager will be shown. If a
	   seat is specified, properties of the seat are shown. By default, empty properties are suppressed. Use --all to show those too. To
	   select specific properties to show, use --property=. This command is intended to be used whenever computer-parsable output is required.
	   Use seat-status if you are looking for formatted human-readable output.

       attach [NAME] [DEVICE...]
	   Persistently attach one or more devices to a seat. The devices should be specified via device paths in the /sys file system. To create
	   a new seat, attach at least one graphics card to a previously unused seat name. Seat names may consist only of a-z, A-Z, 0-9, "-" and
	   "_" and must be prefixed with "seat". To drop assignment of a device to a specific seat, just reassign it to a different seat, or use
	   flush-devices.

       flush-devices
	   Removes all device assignments previously created with attach. After this call, only automatically generated seats will remain, and all
	   seat hardware is assigned to them.

       terminate-seat [NAME...]
	   Terminates all sessions on a seat. This kills all processes of all sessions on a seat and deallocates all runtime resources attached to
	   them.

EXIT STATUS

       On success, 0 is returned, a non-zero failure code otherwise.

ENVIRONMENT

       $SYSTEMD_PAGER
	   Pager to use when --no-pager is not given; overrides $PAGER. Setting this to an empty string or the value "cat" is equivalent to
	   passing --no-pager.
