The purpose of this is to make it easier to maintain and eventually to allow the rclone backends to be re-used in other projects without having to use the rclone configuration system. The new code layout is documented in CONTRIBUTING.

|
|
rclone rcat reads from standard input (stdin) and copies it to a
|
|
single remote file.
|
|
|
|
echo "hello world" | rclone rcat remote:path/to/file
|
|
ffmpeg - | rclone rcat --checksum remote:path/to/file
|
|
|
|
If the remote file already exists, it will be overwritten.
|
|
|
|
rcat will try to upload small files in a single request, which is
|
|
usually more efficient than the streaming/chunked upload endpoints,
|
|
which use multiple requests. Exact behaviour depends on the remote.
|
|
What is considered a small file may be set through
|
|
` + "`--streaming-upload-cutoff`" + `. Uploading only starts after
|
|
the cutoff is reached or if the file ends before that. The data
|
|
must fit into RAM. The cutoff needs to be small enough to adhere
|
|
the limits of your remote, please see there. Generally speaking,
|
|
setting this cutoff too high will decrease your performance.
|
|
|
|
Note that the upload can also not be retried because the data is
|
|
not kept around until the upload succeeds. If you need to transfer
|
|
a lot of data, you're better off caching locally and then
|
|
` + "`rclone move`" + ` it to the destination.`,
