rclone copy works like rsync with a
/ on the end so it only copies the contents. This isn’t a big deal in practice - if you want the actual folder then just name it on the command line.
So lets say /tmp/a has /tmp/a/file.txt in
rclone copy /tmp/a gdrive:
will copy file.txt to gdrive:file.txt
If you want to copy the directory just do
rclone copy /tmp/a gdrive:a
which will copy file.txt to gdrive:a/file.txt
This all makes more sense if you realise that copy is really just
rclone sync under the hood with no deletes, and
sync synchronises two directories which need naming on the command line.
