Use: "about remote:",

Short: `Get quota information from the remote.`,

Long: `
|
|
Get quota information from the remote, like bytes used/free/quota and bytes
|
|
used in the trash. Not supported by all remotes.
|

This will print to stdout something like this:
|
|
|
|
Total: 17G
|
|
Used: 7.444G
|
|
Free: 1.315G
|
|
Trashed: 100.000M
|
|
Other: 8.241G
|
|
|
|
Where the fields are:
|
|
|
|
* Total: total size available.
|
|
* Used: total size used
|
|
* Free: total amount this user could upload.
|
|
* Trashed: total amount in the trash
|
|
* Other: total amount in other storage (eg Gmail, Google Photos)
|
|
* Objects: total number of objects in the storage
|
|
|
|
Note that not all the backends provide all the fields - they will be
|
|
missing if they are not known for that backend. Where it is known
|
|
that the value is unlimited the value will also be omitted.
|
|
|
|
Use the --full flag to see the numbers written out in full, eg
|
|
|
|
Total: 18253611008
|
|
Used: 7993453766
|
|
Free: 1411001220
|
|
Trashed: 104857602
|
|
Other: 8849156022
|
|
|

Use the --json flag for a computer readable output, eg
|
|
|
|

"used": 7993453766,
