Only supply the options you wish to change. If an option is unknown
|
|
it will be silently ignored. Not all options will have an effect when
|
|
changed like this.
|
|
|
|
For example:
|
|
|
|
This sets DEBUG level logs (-vv)
|
|
|
|
rclone rc options/set --json '{"main": {"LogLevel": 8}}'
|
|
|
|
And this sets INFO level logs (-v)
|
|
|
|
rclone rc options/set --json '{"main": {"LogLevel": 7}}'
|
|
|
|
And this sets NOTICE level logs (normal without -v)
|
|
|
|
rclone rc options/set --json '{"main": {"LogLevel": 6}}'
|
|
