Usage:

|
|
rclone backend copyid drive: ID path

|
rclone backend copyid drive: ID1 path1 ID2 path2
|
|
|
|
It copies the drive file with ID given to the path (an rclone path which
|
|
will be passed internally to rclone copyto). The ID and path pairs can be
|
|
repeated.
|
|
|
|
The path should end with a / to indicate copy the file as named to
|
|
this directory. If it doesn't end with a / then the last path
|
|
component will be used as the file name.
|
|
|
|
If the destination is a drive backend then server-side copying will be
|
|
attempted if possible.

Use the -i flag to see what would be copied before copying.
