建议 nmcli，这才是强大的网络管理工具

ip, ifconfig, iwconfig 这些都只是网络接口/无线设备的管理工具

找一个临时目录，将上面内容存储为 test.sh, 执行 bash test.sh 你将会得到这些东西

这个命令最主要的入口帮助，从 nmcli 主命令开始，向下的所有子命令操作，以及子命令的子命令与各层命令的参数，(理论上可无限层，基本上是有限层

以上只是一个 nmcli 命令的简单(傻瓜式)处理方式，当然如果你有想法，可自己处理 ip/iptable/ipset/ifconfig/ 以及各种命令的帮助集合(如果你会编程，你自然可以找出规律，将这些命令的组合制成一个图形化工具，鼠标点点点就能看到你想知道的帮助内容，所以，是重复(傻瓜式)处理方式，还是寻找更高级的操作而一劳永亦呢

补充：我并没有正面回答 "请问如何用ip命令管理无线网络，比如连接WiFi ？谢谢" 这个问题，只是随便说说(仅我目前所知道的一些内容

非常感谢

nmtui更适合普通人

当然，GUI是最棒的

Arch下用过iwctl，很好用，但deepin中好像没有
