Usage:

|
This will return a JSON list of objects like this
|

|
|
"name": "Test Drive"
|
|
}
|
|
]
|
|
|
|
With the -o config parameter it will output the list in a format

suitable for adding to a config file to make aliases for all the
|
|
drives found and a combined drive.
|
|
|
|
[My Drive]

[AllDrives]
|
|

|
|
upstreams = "My Drive=My Drive:" "Test Drive=Test Drive:"
|
|
|
|
Adding this to the rclone config file will cause those team drives to
|
|
be accessible with the aliases shown. Any illegal characters will be
|
|
substituted with "_" and duplicate names will have numbers suffixed.
|
|
It will also add a remote called AllDrives which shows all the shared
|
|
drives combined into one directory tree.

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

|
|
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

The query syntax is documented at [Google Drive Search query terms and

operators](https://developers.google.com/drive/api/guides/ref-search-terms).
|
|
|
|
For example:
|
|
|
|
rclone backend query drive: "'0ABc9DEFGHIJKLMNop0QRatUVW3X' in parents and name contains 'foo'"
|
|
|
|
If the query contains literal ' or \ characters, these need to be escaped with
|
|
\ characters. "'" becomes "\'" and "\" becomes "\\\", for example to match a
|
|
file named "foo ' \.txt":
|
|
|
|
rclone backend query drive: "name = 'foo \' \\\.txt'"
|
|
|
|
The result is a JSON array of matches, for example:
