	Use:   "lsd remote:path",
	Short: `List all directories/containers/buckets in the path.`,
	Long: `
Lists the directories in the source path to standard output. Does not
recurse by default.  Use the -R flag to recurse.

This command lists the total size of the directory (if known, -1 if
not), the modification time (if known, the current time if not), the
number of objects in the directory (if known, -1 if not) and the name
of the directory, Eg

    $ rclone lsd swift:
          494000 2018-04-26 08:43:20     10000 10000files
              65 2018-04-26 08:43:20         1 1File

Or

    $ rclone lsd drive:test
              -1 2016-10-17 17:41:53        -1 1000files
              -1 2017-01-03 14:40:54        -1 2500files
              -1 2017-07-08 14:39:28        -1 4000files

If you just want the directory names use "rclone lsf --dirs-only".
