Disable Host Key Checking

How to suppress typing “yes” when prompted by ssh.

<pre lang="bash">
#!/bin/bash
ssh-keygen -f "/home/user/.ssh/known_hosts" -R "yourdomain.com" 
ssh -o "StrictHostKeyChecking=no" -i "keys/key.pem" ubuntu@domain.com

1. First remove old keys in the know_hosts file.
2. Use “StrictHostKeyChecking” to suppress prompt.
