将Windows cmd stdout和stderr重定向到单个文件 [英] Redirect Windows cmd stdout and stderr to a single file

问题描述

我正在尝试将 DOS 命令的所有输出(stdout + stderr)重定向到单个文件:

I'm trying to redirect all output (stdout + stderr) of a DOS command to a single file:

C:\>dir 1> a.txt 2> a.txt
The process cannot access the file because it is being used by another process.

有可能还是应该只重定向到两个单独的文件?

Is it possible, or should I just redirect to two separate files?

推荐答案

您要:

dir > a.txt 2>&1

语法2>&1会将2(stderr)重定向到1(stdout).您还可以通过重定向到NUL，

The syntax 2>&1 will redirect 2 (stderr) to 1 (stdout). You can also hide messages by redirecting to NUL, more explanation and examples on MSDN.
