I'm used to tmux but my work environment needs x86 most of the time. So I have to use brew of my x86_64 terminal (Rosetta terminal). But when I do other experimental tasks in my native arm64 terminal, when using tmux I got x86_64 terminal inside tmux pane/window because I installed tmux using x86_64 brew. So I planned to use both flavour of brew…

  echo "x86_64 detected" 
  export PATH=/usr/local/Homebrew/bin:$PATH
else
  echo "arm64 detected"
  # the following line prioritize the arm brew's installation
  export PATH=/opt/homebrew/bin:$PATH
