This may be trivial, but I am not sure how do it safely and optimally.
I have a few servers (AWS EC2) into which I ssh from the bash. Those server names are long.
How can I alias them, so instead of typing the long thing, I can type something like
ssh ubuntu@<alias-name>
This should work:
create a file $HOME/.ssh/config (or in /etc/ssh/ssh_config, if you want to install that alias system-wide), and put the following config inside:
Host myalias Hostname very-long-ugly-fqdn-hostname User ubuntu Port 22 after that, you are able to execute ssh myalias from any shell.
PS: of course, the setting Port 22 is not necessary, since it is default. but this is supposed to show, that you can put any valid ssh option in a Host definition.
