Create a full loop of documentation for rclone about, backends overview and individual backend pages. Discussion: https://github.com/rclone/rclone/pull/4774 relates Previously pull was requested, in part, under ref https://github.com/rclone/rclone/pull/4801 Notes: Introduce a tentative draft see-link format the end of sections to try rather than lots of in-para links. Update about.go incl link to list of backends not supporting about. In list of backends not supporting about, include link to about command reference. I appreciate there may be decisions to make going forward about whether command links should be code formatted, and using proper pretty url links, but I have fudged that for now. Update backend pages that do not support about with wording used previously for ftp - it is in passive voice but I can live with it. (my own wording and fault). The note is applied to a limitations section. If one does not already exist it is created (even if there are other limitations with their own sections)

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: 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 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
|
|
|
|
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.
|
|
|
|
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 computer readable output, e.g.
|
|
|
|
{
|
|
"total": 18253611008,
|
|
"used": 7993453766,
|
|
"trashed": 104857602,
|
|
"other": 8849156022,
|
|
"free": 1411001220
|
|
}
|
|
|
|
Not all backends support the ` + "`rclone about`" + ` command.
