systemd Developer Lennart Poettering lennart@poettering.net machinectl 1 machinectl Control the systemd machine manager machinectl OPTIONS COMMAND NAME machinectl may be used to introspect and control the state of the systemd1 virtual machine and container registration manager systemd-machined.service8. The following options are understood: -p --property= 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. -a --all When showing machine 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, choose which processes to kill. Must be one of leader, or all to select whether to kill only the leader process of the machine or all processes of the machine. If omitted, defaults to all. -s --signal= When used with kill, 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. --no-legend Do not print the legend, i.e. the column headers and the footer. --mkdir When used with bind creates the destination directory before applying the bind mount. --read-only When used with bind applies a read-only bind mount. The following commands are understood: list List currently running virtual machines and containers. status NAME... 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 show instead. show NAME... 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 NAME is specified, properties of this virtual machine or container 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 status if you are looking for formatted human-readable output. login NAME 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 systemd1 as init system. reboot NAME... Reboot one or more containers. This will trigger a reboot by sending SIGINT to the container's 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. poweroff NAME... Power off one or more containers. This will trigger a reboot by sending SIGRTMIN+4 to the container's init process, which causes systemd-compatible init systems to shut down cleanly. This operation does not work on containers that do not run a systemd1-compatible init system, such as sysvinit. kill NAME... 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 --kill-who= to select which process to kill. Use --signal= to select the signal to send. terminate NAME... Terminates a virtual machine or container. This kills all processes of the virtual machine or container and deallocates all resources attached to that instance. bind NAME PATH [PATH] Bind mounts a directory from the host into the specified container. The first directory argument is the source directory on the host, the second directory argument the source directory on the host. When the latter is omitted the destination path in the container is the same as the source path on the host. When combined with the --read-only switch a ready-only bind mount is created. When combined with the --mkdir switch the destination path is first created before the mount is applied. Note that this option is currently only supported for systemd-nspawn1 containers. copy-to NAME PATH [PATH] Copies files or directories from the host system into a running container. Takes a container name, followed by the source path on the host and the destination path in the container. If the destination path is omitted the same as the source path is used. copy-from NAME PATH [PATH] Copies files or directories from a container into the host system. Takes a container name, followed by the source path in the container the destination path on the host. If the destination path is omitted the same as the source path is used. On success, 0 is returned, a non-zero failure code otherwise. systemd-machined.service8, systemd-nspawn1, systemd.special7
