title: The 66 Suite: enable author: Eric Vidal <eric@obarun.org> [66](index.html) [Software](https://web.obarun.org/software) [obarun.org](https://web.obarun.org) # enable This command enables one or more services within a specified *tree* depending of the method used. ## Interface ``` enable [ -h ] [ -S ] service(s) ``` This command will also parse the service if it was never parsed. The *service* will then be available in the given *tree* for the next boot depending on the state of the *tree*. The targeted service(s) can also be started on the fly when enabling it with the **-S** option. The given *tree* can be define through the `-t` option in the `66` general option or by using the `@intree` field within the frontend file or setting a current tree through the [66 tree current](66-tree.html) subcommand. If neither `-t` options nor `@intree` is provided, or if no tree is marked as a current one, it will enable the service within the default tree named `%%default_treename%%`. The default tree name can be changed at compile time by passing the `--with-default-tree-name` to `./configure`. In case of `module` service type, all services within the `module` are enabled. Multiple *services* can be enabled by seperating their names with a space. This command handles [interdependencies](66.html#handling-dependencies). ## Options - **-h**: prints this help. - **-S**: starts the *service* on the fly directly after enabling it. If the state of the *service* is already up, this option will have no effect. This also applies to the dependencies of the service. ## Usage examples Enable a service while specifying with the tree name(this only takes effect if the service has not been parsed before): ``` 66 -t treeA enable foo ``` Enable an instanced service: ``` 66 enable foo@foobar ``` Enable and start the service, also increase the default verbosity: ``` 66 -v3 enable -S foo ```
