I don’t remember where I found it, but I’ve been using this without any issues for quite some time:

#!/usr/bin/env bash

function tnew() {
  if [ -z "$1" ]; then
    session_name=$(basename $PWD:gs/./)
  else
    session_name=$1
  fi
  tmux new-session -As $session_name -n 'main'
}

From the manual: The -A flag makes new-session behave like attach-session if session-name already exists.
