Short: `Run rclone listening to remote control commands only.`,

Long: `
|

This runs rclone so that it only listens to remote control commands.
|
|
|
|
This is useful if you are controlling rclone via the rc API.
|
|
|
|
If you pass in a path to a directory, rclone will serve that directory
|
|
for GET requests on the URL passed in. It will also open the URL in
|
|
the browser when rclone is run.

See the [rc documentation](/rc/) for more info on the rc flags.
