获取无线接口逻辑名称

我尝试获取计算机上可用的所有无线接口。例如，如果我分别使用两个具有逻辑名称wlan0和 的网卡， ra0 那么我想打印它们。

这是我尝试过的，但没有得到任何输出：

sudo lshw -C network | awk 'if (/description: / $2 == "Wireless") {  /logical name: /{printf $3 "\n";}}'

我收到语法错误：

awk: line 1: syntax error at or near if
awk: line 1: syntax error at or near }

不带部分的输出awk：

更新：如果有更好的方法来获得我想要的东西，那么我很乐意接受这样的答案。

答案1

awk -F": " -v line=-1 '{if($2=="Wireless interface"){ line=NR+2}; if (line==NR){print $2}}' youfile
  • -F设置分隔符
  • -v传递一个带有值的变量
  • NR电话号码

我得到后从第二行得到第二项"Wireless interface"
