.SH "NAME"
machinectl \- Control the systemd machine manager
.SH "SYNOPSIS"
.HP \w'\fBmachinectl\fR\ 'u
\fBmachinectl\fR [OPTIONS...] {COMMAND} [NAME...]
.SH "DESCRIPTION"
.PP
\fBmachinectl\fR
may be used to introspect and control the state of the
\fBsystemd\fR(1)
virtual machine and container registration manager
\fBsystemd-machined.service\fR(8)\&.
.SH "OPTIONS"
.PP
The following options are understood:
.PP
\fB\-p\fR, \fB\-\-property=\fR
.RS 4
When showing machine properties, limit the output to certain properties as specified by the argument\&. If not specified, all set properties are shown\&. The argument should be a property name, such as
"Name"\&. If specified more than once, all properties with the specified names are shown\&.
.RE
.PP
\fB\-a\fR, \fB\-\-all\fR
.RS 4
When showing machine properties, show all properties regardless of whether they are set or not\&.
.RE
.PP
\fB\-l\fR, \fB\-\-full\fR
.RS 4
Do not ellipsize process tree entries\&.
.RE
.PP
\fB\-\-kill\-who=\fR
.RS 4
When used with
\fBkill\fR, choose which processes to kill\&. Must be one of
\fBleader\fR, or
\fBall\fR
to select whether to kill only the leader process of the machine or all processes of the machine\&. If omitted, defaults to
\fBall\fR\&.
.RE
.PP
\fB\-s\fR, \fB\-\-signal=\fR
.RS 4
When used with
\fBkill\fR, choose which signal to send to selected processes\&. Must be one of the well\-known signal specifiers, such as
\fBSIGTERM\fR,
\fBSIGINT\fR
or
\fBSIGSTOP\fR\&. If omitted, defaults to
\fBSIGTERM\fR\&.
.RE
.PP
\fB\-\-no\-legend\fR
.RS 4
Do not print the legend, i\&.e\&. the column headers and the footer\&.
.RE
.PP
\fB\-H\fR, \fB\-\-host=\fR
.RS 4
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
\fBmachinectl \-H \fR\fB\fIHOST\fR\fR\&.
.RE
.PP
\fB\-M\fR, \fB\-\-machine=\fR
.RS 4
Execute operation on a local container\&. Specify a container name to connect to\&.
.RE
.PP
\fB\-h\fR, \fB\-\-help\fR
.RS 4
Print a short help text and exit\&.
.RE
.PP
\fB\-\-version\fR
.RS 4
Print a short version string and exit\&.
.RE
.PP
\fB\-\-no\-pager\fR
.RS 4
Do not pipe output into a pager\&.
.RE
.PP
The following commands are understood:
.PP
\fBlist\fR
.RS 4
List currently running virtual machines and containers\&.
.RE
.PP
\fBstatus\fR \fIID\fR\&.\&.\&.
.RS 4
Show terse runtime status information about one or more virtual machines and containers\&. This function is intended to generate human\-readable output\&. If you are looking for computer\-parsable output, use
\fBshow\fR
instead\&.
.RE
.PP
\fBshow\fR \fIID\fR\&.\&.\&.
.RS 4
Show properties of one or more registered virtual machines or containers or the manager itself\&. If no argument is specified, properties of the manager will be shown\&. If an ID is specified, properties of this virtual machine or container are shown\&. By default, empty properties are suppressed\&. Use
\fB\-\-all\fR
to show those too\&. To select specific properties to show, use
\fB\-\-property=\fR\&. This command is intended to be used whenever computer\-parsable output is required\&. Use
\fBstatus\fR
if you are looking for formatted human\-readable output\&.
.RE
.PP
\fBlogin\fR \fIID\fR
.RS 4
Open a terminal login session to a container\&. This will create a TTY connection to a specific container and asks for the execution of a getty on it\&. Note that this is only supported for containers running
\fBsystemd\fR(1)
as init system\&.
.RE
.PP
\fBreboot\fR \fIID\fR\&.\&.\&.
.RS 4
Reboot one or more containers\&. This will trigger a reboot by sending SIGINT to the container\*(Aqs init process, which is roughly equivalent to pressing Ctrl+Alt+Del on a non\-containerized system, and is compatible with containers running any init system\&.
.RE
.PP
\fBpoweroff\fR \fIID\fR\&.\&.\&.
.RS 4
Power off one or more containers\&. This will trigger a reboot by sending SIGRTMIN+4 to the container\*(Aqs init process, which causes systemd\-compatible init systems to shut down cleanly\&. This operation does not work on containers that do not run a
\fBsystemd\fR(1)\-compatible init system, such as sysvinit\&.
.RE
.PP
\fBkill\fR \fIID\fR\&.\&.\&.
.RS 4
Send a signal to one or more processes of the virtual machine or container\&. This means processes as seen by the host, not the processes inside the virtual machine or container\&. Use
\fB\-\-kill\-who=\fR
to select which process to kill\&. Use
\fB\-\-signal=\fR
to select the signal to send\&.
.RE
.PP
\fBterminate\fR \fIID\fR\&.\&.\&.
.RS 4
Terminates a virtual machine or container\&. This kills all processes of the virtual machine or container and deallocates all resources attached to that instance\&.
.RE
.SH "EXIT STATUS"
.PP
On success, 0 is returned, a non\-zero failure code otherwise\&.
.SH "ENVIRONMENT"
.PP
\fI$SYSTEMD_PAGER\fR
.RS 4
Pager to use when
\fB\-\-no\-pager\fR
is not given; overrides
\fI$PAGER\fR\&. Setting this to an empty string or the value
"cat"
is equivalent to passing
\fB\-\-no\-pager\fR\&.
.RE
.PP
\fI$SYSTEMD_LESS\fR
.RS 4
Override the default options passed to
\fBless\fR
("FRSXMK")\&.
.RE
.SH "SEE ALSO"
.PP
\fBsystemd-machined.service\fR(8),
\fBsystemd-nspawn\fR(1),
\fBsystemd.special\fR(7)
