rclone rcat
Copies standard input to file on remote.
Synopsis
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 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.
Use the --size flag to preallocate the file in advance at the remote end
and actually stream it, even if remote backend doesn't support streaming.
--size should be the exact size of the input stream in bytes. If the
size of the stream is different in length to the --size passed in
then the transfer will likely fail.
Note that the upload cannot be retried because the data is not stored.
If the backend supports multipart uploading then individual chunks can
be retried. If you need to transfer a lot of data, you may be better
off caching it locally and then rclone move it to the
destination which can use retries.
