Use an alias to quickly list all SSH hosts defined in your SSH config
I use an SSH config file to manage the details of all the SSH hosts I connect to.
Sometimes I need to audit the hosts in my SSH config.
This can be done using the following:
grep -P "^Host ([^*]+)$" $HOME/.ssh/config | sed 's/Host //'
This command will exclude wildcard definitions leaving you with just the explicitly named hosts.
So that I don't have to remember this everytime, I've added this as an alias to my .zshrc file:
... # Aliases # List SSH hosts from SSH config alias ssh-hosts="grep -P \"^Host ([^*]+)$\" $HOME/.ssh/config | sed 's/Host //'" ...
