将批处理命令输出到变量 [英] Outputting Batch Command to Variable

问题描述

我在批处理脚本方面没有很强的背景，因此，如果有明显的答案，我们深表歉意.

I do not have a strong background in batch scripts, so apologies if there is an obvious answer.

我正在尝试将命令提示符的输出定向到变量.我可以将其输出到这样的文件

I am trying to direct the output of a command prompt to a variable. I can output it to a file like this

go test -race > output.txt

在这种情况下，将使用go test -race的输出填充output.txt.我想做的就是将其输出到一个变量，类似

In this case, output.txt gets populated with the output of go test -race. What I am trying to do is output it to a variable, something along the lines of

set iamavariable=nothotdog
go test -race > %iamavariable%
echo %location%

这将创建一个名为nothotdog的文件，该文件具有go test -race的输出，并且回显nothotdog，而不是回显go test -race的输出

This creates a file called nothotdog that has the output of go test -race, and echoes nothotdog, instead of echoing the output of go test -race

推荐答案

要正确获取命令结果，您需要一个for循环.

To correctly get the result of a command, you need a for loop.

for /f %%p in ('your command') do set result=%%p
echo %result%

如果命令输出的不只是单个单词/数字/字符/数字，那么可能会更好:

---

If the command was outputting more than a single word/number/character/digit then perhaps this would be better:

For /F "Delims=" %%A In ('go test -race') Do Set "result=%%A"
Echo %result%
