Before this change if we copied files of unknown size, then they lost their metadata. This was particularly noticeable using --s3-decompress. This change adds metadata to Rcat and RcatSized and changes Copy to pass the metadata in when it calls Rcat for an unknown sized input. Fixes #6546

Title: "Runs a backend command.",
|
|
Help: `This takes the following parameters:
|
|
|
|
- command - a string with the command name
|
|
- fs - a remote name string e.g. "drive:"
|
|
- arg - a list of arguments for the backend command
|
|
- opt - a map of string to string of options
|
|
|
|
Returns:
|
|
|
|
- result - result from the backend command
|
|
|
|
Example:
|
|
|
|
rclone rc backend/command command=noop fs=. -o echo=yes -o blue -a path1 -a path2
|
|
|
|
Returns
|
|
|
|
` + "```" + `

|
|
"result": {
|
|
"arg": [
|
|
"path1",

|
"path2"
|

"name": "noop",

"echo": "yes"

Note that this is the direct equivalent of using this "backend"

command:
|
|
|
|
rclone backend noop . -o echo=yes -o blue path1 path2
