+### Wildcards
+
+The `rm` command can be used in conjunction with an asterisk to delete multiple items matching a specific set of criteria. For example, you could use `rm test*` to remove all files in a directory starting with "test" regardless of whatever text follows that string. You can also use an asterisk by itself to purge all files in the current directory using `rm *`.
