Problem Description：How does WSL and WSL2 realize that as soon as bash is opened, it is possible to interactively choose whether to visualize or not visualize the configuration through VcXsrv?

核心思路：参考WSL，WSL2多个想source的环境变量，如何在.bashrc内基于if-else进而在bash内可交互式进行选择？而不用每次使用复杂指令

  • if-else判选+read获取值+echo打印

可视化配置

  • 用代码编辑器，如Notepad++打开\\wsl$\Ubuntu-20.04\root\.bashrc，在最下方添加以下内容

# 可视化
echo ""
echo ""
echo "=================================================="
echo "Please input the visible mode you want to choose :"
echo "1. Default: Just Print Here"
echo "2. Display through VcXsrv"
echo "=================================================="
echo "The visible mode you want to choose is :"
read visType

echo "=================================================="
echo "Processing ..."
echo "=================================================="
echo "The environment you choose is :"
if ((visType == 1)); then   
  echo "1. Default: Just Print Here"

elif ((visType == 2)); then
  echo "2. Display through VcXsrv"
  export DISPLAY=`cat /etc/resolv.conf | grep nameserver | awk '{print $2}'`:0 # 这是WSL2的可视化配置
  
else   
  echo "Type Error !"
fi

echo "=================================================="
echo "Activating ..."
echo "=================================================="
echo "Display mode activate succeed !"
echo "=================================================="
echo ""
echo ""

效果
