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

Original code for bash from @florianbeer: https://gist.github.com/florianbeer/ee02c149a7e25f643491

replace

set ps_res (ps -p (ps -p %self -o ppid= | xargs) -o comm=)
if [ "$ps_res" = "tmux" ]

with
if test -n $TMUX
or
if set -q TMUX

Hi Mate, I know you asked to copy this code into fish terminal, I am using kitty, can you help to make it work here? All I need when I ssh to remote server I want to see title or status bar with remote hostname and when exit it, it should return to my local computer name.

On modern tmux line 8 seems to be rather:

    tmux set -w automatic-rename "on"

@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.
