When I type passwd, I get

Changing password for <user>.

(current) UNIX password:

Now suppose at this point I change my mind and I decide to stay with my old password. What should I do?

Ctrl + C doesn't work. The only way I found is to use a second command line to find out the PID or the running passwd process and then feed it to kill -9 (the standard kill doesn't work either).

Is there a better way, preferably not involving a second command line?
