+Copy the contents of **src_path** to the **dest_path**. You can copy from the container's filesystem to the local machine or the reverse, from the local filesystem to the container or between two containers.
If `-` is specified for either the SRC_PATH or DEST_PATH, you can also stream a tar archive from STDIN or to STDOUT.
-The CONTAINER can be a running or stopped container. The **src_path** or **dest_path** can be a file or directory.
