#do_scp_to(source, target_path, options) ⇒ Object
scp files from the localhost to this test host, if a directory is provided it is recursively copied. If the provided source is a directory both the contents of the directory and the directory itself will be copied to the host, if you only want to copy directory contents you will either need to specify the contents file by file or do a separate ‘mv’ command post scp_to to create the directory structure as desired. To determine if a file/dir is ‘ignored’ we compare to any contents of the source dir and NOT any part of the path to that source dir.
