Set tmux pane title to short hostname on ssh connections for Fish

set-tmux-title

# Copy that into your ~/.config/fish/config.fish

function ssh
  set ps_res (ps -p (ps -p %self -o ppid= | xargs) -o comm=)
  if [ "$ps_res" = "tmux" ]
    tmux rename-window (echo $argv | cut -d . -f 1)
    command ssh "$argv"
    tmux set-window-option automatic-rename "on" 1>/dev/null
  else
    command ssh "$argv"
  end
end

@nippyin This code is not dependent on the terminal; it's for tmux (which you run inside the terminal), using the fish shell. If you're using tmux and fish inside kitty, you can use the code above.

If you don't use tmux, you can use kitty @ set-window-title and kitty @ set-tab-title to configure the kitty window. You'll have to add allow_remote_control to your kitty.conf file first.

If you use tmux but bash or other shell, adapt the function to your shell, or look online (people have made a number of versions).

Thanks it works.
