What Others Think

A couple of things. First, the description should be changed. You're not "Remov[ing] a line from a file using sed". You're removing a host from your ~/.ssh/known_hosts file with ssh-keygen(1). Second, this has been submitted already: That's just after a quick search. I'm sure there are more. So, not to sound like a grump, but next time, search the archive.
