The above suggestion doesn't work because the ls command fails. It's
also a very roundabout way to delete a file. There is no need to use
i-numbers.

The manual page for rm says:
    To  remove a file whose name starts with a ‘-’, for example ‘-foo’,
    use one of these commands:

        rm -- -foo

        rm ./-foo

Using "--" to separate flags/options from filenames works for many
commands, including ls.
