What Others Think

Probably you want '~/.ssh/known_hosts' (mind the final 's').

This command isn't portable across unices, has a typo, and requires you to know the line before running this command. Using ssh-keygen(1) is the preferred, portable way.

Portable is relative. I have an old Redhat system here that doesn't even know the -i switch to sed ;)
