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 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 unit/job/manager properties, show all properties regardless whether they
           are set or not.

       --full
           Do not ellipsize cgroup members.

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

       --no-ask-password
           Don't 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 is 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 is 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 aren't 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.
