ApacheBench 结果到文件

Question

我想将 linux 上的 ApacheBench (ab) 工具保存到一个文件中。当我使用 -v 2 运行它时，它会在我的 ssh 窗口中显示一些结果。如何将这些数据移动到文件中并确保它不再显示在 ssh 上？我试过 > file.txt 2>&1 但它不起作用并且仍然在我的 ssh 窗口中显示数据。

我用：

ab -n 10000 -c 200 http://mywebsite.com > file.txt 2>&1

Answer 1

对不起，除了猫便便什么都没有。

我确实注意到 ab 对我不起作用，除非 url 末尾有文件名或 /。

但是，错误仍然会进入文件。

这是你在做什么？（当然，在本地主机以外的地方）

pjb@pjb-desktop:~$ ssh localhost -l pjb

pjb@pjb-desktop:~$ ab -v 2 -n 10000 -c 200 http://localhost/ > poo 2>&1

什么也看不见。

都在猫屎里。

使用 -v2，您可以在猫便便中获得很多这些

否则没有 -v2 它看起来像这样
