title: Ubuntu terminal ssh to same ip after device changed
body: <p>I ssh to a device that gets attached to a test bench with the following:<code>ssh root@1.2.3.4</code></p>
  <p>Because the actual device has been changed since the last time I connected to that IP I get:<code>WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!</code> all as expected. The warning tells me that I can easily fix this with <code>ssh-keygen -f &quot;/home/myuser/.ssh/known_hosts&quot; -R &quot;1.2.3.4&quot;</code></p>
  <p>I do find it repeating the same thing over and over, there must be some way to improve this. I know this IP and it is internal to my company.</p>
  <p>I started working on trying to use something like <code>!!:s/find/replace</code> but the spaces in the replace is making my life difficult.</p>
  <p>What is the easiest way to automate this, maybe create an alias?</p>
  <p>Thank you
