LOGINCTL(1)                                  loginctl                                 LOGINCTL(1)



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:

       --no-legend
           Do not print the legend, i.e. the column headers and the footer.

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

       -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.

       --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 the operation remotely. Specify a hostname, or a username and hostname
           separated by "@", to connect to. The hostname may optionally be suffixed by a
           container name, separated by ":", which connects directly to a specific container on
           the specified host. This will use SSH to talk to the remote machine manager instance.
           Container names may be enumerated with machinectl -H HOST.

       -M, --machine=
           Execute operation on a local container. Specify a container name to connect to.

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

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

       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 the user 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 the
           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.

       $SYSTEMD_LESS
           Override the default options passed to less ("FRSXMK").
