In addition, when using rm --help, you will find the following very useful things in the description

1. By default, rm does not delete the directory. Use the --recursive (-r or -R) option to remove each listed

2. directory and its contents below.

3. To delete the first character (“-foo”), use one of the following methods:

4. rm -- -foo

5. rm . /-foo
