Question

我正在努力解决以下问题。我在终端运行这个命令：

airport en1 -s

结果我得到一个看起来像这样的wifi网络列表：

SSID BSSID             RSSI CHANNEL HT CC SECURITY (auth/unicast/group)
eduroam 00:25:84:36:b1:0d -76  40      N  NL WPA2(802.1x/AES/AES)

eduroam 00:17:df:2d:51:a2 -72  1       N  NL WPA2(802.1x/AES/AES)

现在我希望终端计算列表（没有第一行）

我已经尝试过：**ls airport en1 -s**但这不起作用。还尝试了：**grep -Rl "*keyword*" ./ | wc -l**

感谢任何提示！

Answer 1

your command...|awk 'END{print NR--}'

将计算没有第一行的行。（总行数-1）

如果你想做一些grep，你可以这样做：

your command...|grep -c 'keyword'

终端：计算“输出列表”
