从airodump中-NG阅读实时输出 [英] Reading realtime output from airodump-ng

问题描述

当我执行命令airodump中 - ng的MON0 >> output.txt的，output.txt的是空的。我需要能够运行airodump中-纳克MON0和大约5秒后停止命令，比能够获得它的输出。任何想法，我应该开始看？我使用bash。

When I execute the command airodump-ng mon0 >> output.txt , output.txt is empty. I need to be able to run airodump-ng mon0 and after about 5 seconds stop the command , than have access to its output. Any thoughts where I should begin to look? I was using bash.

推荐答案

作为后台进程启动命令，睡眠5秒，然后杀死后台进程。您可能需要重定向比STDOUT不同的流对于在文件中捕获的输出。 这个线程提到STDERR（这将是FD 2）。我不能在这里验证这一点，但你可以检查与 strace的描述符数量。该命令应显示是这样的：

Start the command as a background process, sleep 5 seconds, then kill the background process. You may need to redirect a different stream than STDOUT for capturing the output in a file. This thread mentions STDERR (which would be FD 2). I can't verify this here, but you can check the descriptor number with strace. The command should show something like this:

$ strace airodump-ng mon0 2>&1 | grep ^write
...
write(2, "...

在数写语句是文件描述符 airodump中-NG 写入

The number in the write statement is the file descriptor airodump-ng writes to.

脚本可能看起来有点像这样（假设STDERR需要重定向）：

The script might look somewhat like this (assuming that STDERR needs to be redirected):

#!/bin/bash

{ airodump-ng mon0 2>> output.txt; } &
PID=$!

sleep 5

kill -TERM $PID
cat output.txt
