+# Remove A Directory Called `-p`
+
+I accidentally created a directory from the terminal called `-p`. It is sitting
+there next to other directories like `app` and `public`. I need to get rid of
+it. The `rmdir` command is the best way to do that.
+
+```bash
+$ rmdir -p
+usage: rmdir [-p] directory ...
+```
+
+Not so fast. `-p` is also a valid flag for the `rmdir` command. It doesn't know
+that I mean it as the name of the directory. So instead, I am missing a
+required argument to `rmdir` – the directory.
+
+To get this to work, I need to tell `rmdir` that I intend `-p` as the name of
+the directory to remove.
+
+```
+$ rmdir -- -p
+```
+
+The `--` is a command-line convention. It tells the command that anything after
+the `--` is not a flag, but instead an argument. This time the `-p` directory
+will be removed.
