title: tmux - disable beep on attach/detach
body: <p>I am using mcabber with beep option inside tmux. I want mcabber to beep,but don't want tmux to beep on startup, attach or detach.</p>
  
  <pre><code># disable sound bell
  set -g bell-action none
  # disable visual bell
  set -g visual-bell off
  </code></pre>
  
  <p>I found this, but this disables mcabber beeps and do not disable attach/detach beep. How to disable attach/detach beep in tmux?</p>
