Команды (Commands)

The following commands are understood:

Session Commands list-sessions List current sessions.

session-status [ID...] Show terse runtime status information about one or more sessions, followed by the most recent log data from the journal. Takes one or more session identifiers as parameters. If no session identifiers are passed, the status of the caller's session is shown. 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 a session. This brings a session into the foreground if another session is currently in the foreground on the respective seat. Takes a session identifier as argument. If no argument is specified, the session of the caller is put into foreground.

lock-session [ID...], unlock-session [ID...] Activates/deactivates the screen lock on one or more sessions, if the session supports it. Takes one or more session identifiers as arguments. If no argument is specified, the session of the caller is locked/unlocked.

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. If the argument is specified as empty string the session invoking the command is terminated.

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. If the argument is specified as empty string the signal is sent to the session invoking the command.

User Commands list-users List currently logged in users.

user-status [USER...] Show terse runtime status information about one or more logged in users, followed by the most recent log data from the journal. Takes one or more user names or numeric user IDs as parameters. If no parameters are passed, the status is shown for the user of the session of the caller. This function is intended to generate human-readable output. If you are looking for computer-parsable output, use show-user instead.

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. Takes one or more user names or numeric UIDs as argument. If no argument is specified, enables/disables lingering for the user of the session of the caller.

See also KillUserProcesses= setting in logind.conf(5).

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. If the argument is specified as empty string the sessions of the user invoking the command are terminated.

kill-user USER... Send a signal to all processes of a user. Use --signal= to select the signal to send. If the argument is specified as empty string the signal is sent to the sessions of the user invoking the command.

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

seat-status [NAME...] Show terse runtime status information about one or more seats. Takes one or more seat names as parameters. If no seat names are passed the status of the caller's session's seat is shown. 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.
