sshostnew () {sed -i "$1d" $HOME/.ssh/known_hosts ; }
If you work in an environment, where some ssh hosts change regularly this might be handy...

What Others Think

ssh-keygen can do this for you: ssh-keygen -R <hostname> ssh-keygen --help 2>&1 | grep -- -R -R hostname Remove host from known_hosts file.

Uhh nice. For my special use I'll continue use the function, since the line in known_hosts is just 2 digits and the "hostname" some v6 address... --help is not an option of openssh ssh-keygen. Anyway, thanks for the hint!
