NAME¶
loginctl - Control the systemd login managerSYNOPSIS¶
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, --helpPrints 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_PAGERPager 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.
