[SOLVED] Can't create a new session from `run-shell` in tmux

Issue

I have this +x script

~/bin/tmux-test.sh:

#!/usr/bin/bash

tmux neww

and in my .tmux.conf:

bind -n M-g run-shell `~/bin/tmux-test.sh`

It works...
...but if I change tmux neww to tmux new (for creating a new session) then when I press the keybind tmux shows this error on screen :

'/home/me/bin/tmux-test.sh' returned 1

What am I doing wrong?

Solution

First, tmux does not support `..` style quoting.

And by default tmux new (not :new) would refuse to create new session if you are already in tmux:

$ echo $TMUX
/private/tmp/tmux-502/default,2554,0
$ tmux new
sessions should be nested with care, unset $TMUX to force

You can use tmux new -d to create a detached session and then switch to it.

~/bin/tmux-test.sh

tmux new -d -s foo
tmux switch-client -t foo
true

tmux.conf

bind -n M-g run-shell ~/bin/tmux-test.sh
