Options The following options are understood: Prints a short help text and exits. Prints a short version string and exits. 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. When showing unit/job/manager properties, show all properties regardless whether they are set or not. Do not pipe output into a pager. When used with kill-session, choose which processes to kill. Must be one of , or to select whether to kill only the leader process of the session or all processes of the session. If omitted defaults to .

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 to show those too. To select specific properties to show use . 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 [ID...] unlock [ID...] Activates/deactivates the screen lock on one or more sessions, if the session supports 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 to select which process to kill. Use 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.

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 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 to show those too. To select specific properties to show use . 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...] 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 names. 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.
