the hints about truncated log lines. This does not suppress output of commands for which the printed output is the only result (like show). Errors are
           always printed.

       --no-warn
           Don't generate the warnings shown by default in the following cases:

           •   when systemctl is invoked without procfs mounted on /proc/,

           •   when using enable or disable on units without install information (i.e. don't have or have an empty [Install] section).

       --no-block
           Do not synchronously wait for the requested operation to finish. If this is not specified, the job will be verified, enqueued and systemctl will wait until the unit's start-up is completed. By passing this
           argument, it is only verified and enqueued. This option may not be combined with --wait.

       --wait
           Synchronously wait for started units to terminate again. This option may not be combined with --no-block. Note that this will wait forever if any given unit never terminates (by itself or by getting stopped
           explicitly); particularly services which use "RemainAfterExit=yes".

           When used with is-system-running, wait until the boot process is completed before returning.

       --user
           Talk to the service manager of the calling user, rather than the service manager of the system.

       --system
           Talk to the service manager of the system. This is the implied default.

       --failed
           List units in failed state. This is equivalent to --state=failed.

       --no-wall
           Do not send wall message before halt, power-off and reboot.

       --global
           When used with enable and disable, operate on the global user configuration directory, thus enabling or disabling a unit file globally for all future logins of all users.

       --no-reload
           When used with enable and disable, do not implicitly reload daemon configuration after executing the changes.

       --no-ask-password
           When used with start and related commands, disables asking for passwords. Background services may require input of a password or passphrase string, for example to unlock system hard disks or cryptographic
           certificates. Unless this option is specified and the command is invoked from a terminal, systemctl will query the user on the terminal for the necessary secrets. Use this option to switch this behavior off. In
           this case, the password must be supplied by some other means (for example graphical password agents) or the service might fail. This also disables querying the user for authentication for privileged operations.

       --kill-whom=
           When used with kill, choose which processes to send a signal to. Must be one of main, control or all to select whether to kill only the main process, the control process or all processes of the unit. The main
           process of the unit is the one that defines the life-time of it. A control process of a unit is one that is invoked by the manager to induce state changes of it. For example, all processes started due to the
           ExecStartPre=, ExecStop= or ExecReload= settings of service units are control processes. Note that there is only one control process per unit at a time, as only one state change is executed at a time. For services
           of type Type=forking, the initial process started by the manager for ExecStart= is a control process, while the process ultimately forked off by that one is then considered the main process of the unit (if it can
           be determined). This is different for service units of other types, where the process forked off by the manager for ExecStart= is always the main process itself. A service unit consists of zero or one main
           process, zero or one control process plus any number of additional processes. Not all unit types manage processes of these types however. For example, for mount units, control processes are defined
