+BAMBU_SERIAL
+BAMBU_ACCESS_CODE
+
+Subcommands:

+         ls [--list-only] [--file] [path]

+                  of files without metadata (timestamp, etc.).
+                  If "--file" is specified, then <path> is assumed

+         rm [-r|--recursive] <path>
+                - Delete the remote <path> on the printer.
+                  If "-r" is specified, assume <path> is a directory and
+                  delete all of its children, including itself.
