Dojo: Count the Failed Logins

The auth log /root/auth.log is full of SSH events. In ONE line, count how many failed-password attempts it contains and write just that number to /root/answer.txt.

Any correct answer earns the pass — but the Dojo grades your elegance. The tightest correct one-liner earns ★★★. There's a well-known trap here: counting matches by piping grep into wc -l works, but grep can count by itself. Beat par.
