This command is useful to apply or undo the installation instructions encoded in the [Install] section of unit files. See systemd.unit5 for more information. Enabling units (as with systemd-install enable) should not be confused with activating units (as with systemctl start). The former simply installs the unit files in the configuration tree, but does not start them. The latter equals starting them, but does not necessarily require them to be enabled. Options The following options are understood: Prints a short help text and exits. Enable/disable a service even if it conflicts with/contradicts another service. This might have the effect of disabling another service that was enabled. Enable/disable a system service. Enable/disable a session service for the calling user. Enable/disable a session service for all users. After enabling/disabling stop/restart/stop the unit and reload manager configuration. Optionally, takes one of , , , or .

If is passed the daemon configuration is reloaded but the unit otherwise not started/stopped/restarted. If is passed and a unit is being enabled it will also be restarted should it already be running. If a unit is being disabled it will be stopped should it be running. In either case the daemon configuration is reloaded. is similar to this, but the unit will also be started if it is being enabled and any of the units listed in WantedBy= in the [Install] section of the unit file is already activated. Finally starts the unit unconditionally after enabling. This setting defaults to . If the mode value is omitted defaults to . This option has no effect when or test is used, or when systemd is not running or the command is executed in a chroot2 environment. The following commands are understood: enable Enable a unit. This will create a number of symlinks as encoded in the [Install] section of a unit file. disable Disable a unit. This will remove a number of symlinks as encoded in the [Install] section of a unit file. test Checks whether any of the units specified are installed. This will check for the existence of a number of symlinks as encoded in the [Install] section of a unit file. Exit status On success 0 is returned, a non-zero failure code otherwise.
