So an addition to the bash script could look like: The command will run and add the remote SSH fingerprint to the local machine, without your input ( Figure B). To add that fingerprint, the command would be: Let’s say the remote server is at 192.168.1.162. I’ll demonstrate adding the fingerprint from a remote serve to a local machine. So what happens when you’re working with a bash script that cannot accept input, in order to okay the addition of the remote SSH fingerprint?įortunately, the developers of SSH thought of this, and have added a command that allows you to easily add SSH fingerprints to the known_hosts file.
