Two tips about iTerm2
Add a badge to the window
When working with multiple HPCs, it’s nice to have the host name printed on each terminal window. To do it, the first step is to install shell integration on each remote host. Simply go to iTerm2 -> Install Shell Integration -> Download and run installer. iTerm2 will then run a command line automaticlly. Once it’s complete, the next step is adding \(session.hostname) in Badge under Profiles -> General. There are some other contents to show. See here.
Save log-in information for quick connection
You can do it by creating a new profile, then under Profiles -> General -> Command, add a ssh command. According to this page, this seems the only way to do it.
