How to distinguish a terminal window currently connected via SSH? I'm coming from Windows, where I used to use Putty whenever I needed to connect to a server via SSH.

On MacOS this is much easier, as I can ssh into the server directly from the terminal. This is nice, but comes with a caveat: I might have a few terminal windows open at the same time, and mistake a terminal opened locally with a terminal ssh'ed into a remote server (and make nasty mistakes).

Is there any way I can visually distinguish a terminal window connected via ssh, from another one on my local machine?
Look to the title of the window, or the title of the tab if you are using several tabs:

  I was thinking about something like the window changing color somewhere. Don't even know if that's technically possible, though. – Benjamin


Assuming a worst case when you are unable to change remote's prompt, edit you mac's terminal prompt in order to make most clear if the terminal is at a client of a Mac of yours.

If you use Tmux, configure non defaults status-fg status-bg so that your Mac's local terminals use a different Tmux color than what is configured at your servers.
