wsl2 代理脚本proxy.sh

wsl2 开发时使用宿主系统的proxy，

在宿主机D盘创建文件：proxy.sh，代码在最后。

拷到wsl的用户根目录，

rm -rf ~/proxy.sh
cp /mnt/d/proxy.sh ~/

使用方式：

source ~/proxy.sh set
source ~/proxy.sh test
source ~/proxy.sh unset

proxy.sh脚本

#!/bin/sh
# source ~/proxy.sh set 开启代理
# source ~/proxy.sh unset 关闭代理
# source ~/proxy.sh test 查看代理

wslip=$(hostname -I | awk '{print $1}')
