This adds an additional parameter to the creation of each flag. This specifies one or more flag groups. This **must** be set for global flags and **must not** be set for local flags. This causes flags.md to be built with sections to aid comprehension and it causes the documentation pages for each command (and the `--help`) to be built showing the flags groups as specified in the `groups` annotation on the command.

Use: "about remote:",
|
|
Short: `Get quota information from the remote.`,
|
|
Long: `
|
|
` + "`rclone about`" + ` prints quota information about a remote to standard
|
|
output. The output is typically used, free, quota and trash contents.
|
|
|
|
E.g. Typical output from ` + "`rclone about remote:`" + ` is:
|
|
|
|
Total: 17 GiB
|
|
Used: 7.444 GiB
|
|
Free: 1.315 GiB
|
|
Trashed: 100.000 MiB
|
|
Other: 8.241 GiB
|
|
|
|
Where the fields are:
|
|
|
|
* Total: Total size available.
|
|
* Used: Total size used.
|
|
* Free: Total space available to this user.
|
|
* Trashed: Total space used by trash.
|
|
* Other: Total amount in other storage (e.g. Gmail, Google Photos).
|
|
* Objects: Total number of objects in the storage.
|
|
|
|
All sizes are in number of bytes.
|
|
|
|
Applying a ` + "`--full`" + ` flag to the command prints the bytes in full, e.g.
|
|
|
|
Total: 18253611008
|
|
Used: 7993453766
|
|
Free: 1411001220
|
|
Trashed: 104857602
|
|
Other: 8849156022
|
|
|
|
A ` + "`--json`" + ` flag generates conveniently machine-readable output, e.g.
|
|
|
|
{
|
|
"total": 18253611008,
|
|
"used": 7993453766,
|
|
"trashed": 104857602,
|
|
"other": 8849156022,
|
|
"free": 1411001220
|
|
}
|
|
|
|
Not all backends print all fields. Information is not included if it is not
|
|
provided by a backend. Where the value is unlimited it is omitted.
|
|
|
|
Some backends does not support the ` + "`rclone about`" + ` command at all,
|
|
see complete list in [documentation](https://rclone.org/overview/#optional-features).
