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: -h --help Prints a short help text and exits. --version Prints a short version string and exits. --no-pager Do not pipe output into a pager. --no-ask-password Do not query the user for authentication for privileged operations. -H --host= Execute the operation remotely. Specify a hostname, or username and hostname separated by @, to connect to. This will use SSH to talk to the remote machine manager instance. -M --machine= Execute the operation on a local container. Specify a container name to connect to. -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-machine, 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-machine, 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. The following commands are understood: list List currently running virtual machines and containers. status ID... 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 ID... 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 --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. terminate ID... Terminates a virtual machine or container. This kills all processes of the virtual machine or container and deallocates all resources attached to that instance. kill ID... 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. reboot ID... 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. login ID 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. On success, 0 is returned, a non-zero failure code otherwise. $SYSTEMD_PAGER Pager 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. $SYSTEMD_LESS $SYSTEMD_LESS overrides the default options passed to less (FRSXMK). systemd-machined.service8, systemd-nspawn1, systemd.special7
