从批处理文件中获取错误code [英] Get error code from within a batch file

问题描述

我有一个运行一对夫妇可执行文件的批处理文件，我希望它退出的成功，但如果停止出口code＆LT;？> 0，我如何做到这一点。

I have a batch file that runs a couple executables, and I want it to exit on success, but stop if the exit code <> 0. How do I do this?

推荐答案

听起来像是你会希望如果ERRORLEVEL命令。假设你的可执行文件失败时返回非0退出code，你做的是这样的：

Sounds like you'll want the "If Errorlevel" command. Assuming your executable returns a non-0 exit code on failure, you do something like:

myProgram.exe
if errorlevel 1 goto somethingbad
echo Success!
exit
:somethingbad
echo Something Bad Happened.

ERRORLEVEL进行检查，以更大，或相等检查，因此，任何非0的退出值将触发跳跃。因此，如果您需要检查一个以上特定的退出值，你应该检查一个最高优先。

Errorlevel checking is done as a greater-or-equal check, so any non-0 exit value will trigger the jump. Therefore, if you need to check for more than one specific exit value, you should check for the highest one first.
