1. First ordered list item
2. Another item
  * Unordered sub-list.
1. Actual numbers don't matter, just that it's a number
  1. Ordered sub-list
4. And another item.

   You can have properly indented paragraphs within list items. Notice the blank line above, and the leading spaces (at least one, but we'll use three here to also align the raw Markdown).

   To have a line break without a paragraph, you will need to use two trailing spaces.
   Note that this line is separate, but within the same paragraph.
   (This is contrary to the typical GFM line break behaviour, where trailing spaces are not required.)

# more command line utilities

The commands will require you to use the `link`, `unlink`, and `rmdir` system commands.

### `rm`

Implement your own version of the `rm` command.  You must be able to support an unlimited number of files passed in as command line parameters.  If any of those files are directories, you must not delete them unless the optional `-r` flag is also present.  Instead, print a warning message.

### `mv`

Implement your own version of the `mv` command.  Given the command:

```
mv file1 file2
```

If `file2` does not exist, then you should rename `file1` to `file1`.  Otherwise, if `file2` is a directory, you should move `file1` into `file2`.  If `file2` is not a directory, you should print an error message.
