推荐答案

p>根据此链接，似乎 -v 参数（和更多）在Windows上被打破。如果你按照网站上的错误链接，似乎有一个解决方法。我引用注释：

According to this link, it seems that the -v argument (and more) is broken on Windows. If you follow the bug link on the site, it seems there is a workaround. I quote the comment:

解决方法（适用于Firefox，
Thunderbird和其他
程序太）：

Workaround (works with Firefox, Thunderbird, and, I suppose, other programs too):

<program-name> -h | more

错误发生是因为没有
重定向，程序会释放
stdout，然后再处理-help
参数。通过重定向，stdout是
未发布，您可以看到
输出。

The bug happens because, without redirection, the program releases its stdout before handling the -help parameter. With redirection, stdout is not released and you can see the output.

：

C:\Program Files (x86)\Mozilla Firefox>firefox -v | more
Mozilla Firefox 3.6.13, Copyright (c) 1998 - 2010 mozilla.org

它至少为我工作。无 |更多我没有打印。在Linux上，它可以使用或不使用管道。

It works for me at least. Without | more I get nothing printed. On Linux it works with or without the piping.
