Debian/Ubuntu 报错解决：-bash: ifconfig: command not found


在WSL里安装了最新的 Debian，然后想查看ip地址的时候报错了：

1. fan@SUN-ACC:/bin$ ifconfig
   
2. -bash: ifconfig: command not found

复制代码

出现这个问题的原因是新版本的Debian 默认不带 ifconfig，官方推荐使用ip命令查看ip：

1. fan@SUN-ACC:/bin$ ip addr
   
2. 16: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 group default qlen 1
