+# free
+
+This command bring down *services* and remove it from the scandir.
+
+## Interface
+
+```
+free [ -h ] [ -P ] service...
+```
+
+This command expects to find an already supervised service. If the state of the *service* is already up, the *free* command stop it first. Subsequently, service is unsupervised from the [scandir](scandir.html), freeing the memory used by the service.
+
+Multiple *services* can be started by separating their names with a space.
+
+In case of `module` *service* type, all *services* declared within the `module` will also be unsupervised. The **-P** has no effect on the *services* within the `module` and only affects the module's dependencies.
+
+This command handles [interdependencies](66.html#handling-dependencies).
+
+## Options
+
+- **-h**: prints this help.
+
+- **-P**: Do not handle service dependencies. In such cases, the *free* command will not attempt to stop the services that are dependent on the service, regardless of their current state.
+
+## Usage examples
+
+Free a service by handling its dependencies.
+
+```
+66 free foo
+```
+
+Free the service without handling any dependencies
+
+```
+66 free -P foo
+```
