如何在遇到错误时终止批处理文件? [英] How do I make a batch file terminate upon encountering an error?

问题描述

我有一个批处理文件，它使用不同的参数一遍又一遍地调用同一个可执行文件.如果其中一个调用返回任何级别的错误代码，如何使其立即终止?

I have a batch file that's calling the same executable over and over with different parameters. How do I make it terminate immediately if one of the calls returns an error code of any level?

基本上，我想要相当于 MSBuild 的 ContinueOnError=false.

Basically, I want the equivalent of MSBuild's ContinueOnError=false.

推荐答案

检查if语句中的errorlevel，然后exit/b(仅退出 batch 文件，而不是整个 cmd.exe 进程)对于 0 以外的值.

Check the errorlevel in an if statement, and then exit /b (exit the batch file only, not the entire cmd.exe process) for values other than 0.

same-executable-over-and-over.exe /with different "parameters"
if %errorlevel% neq 0 exit /b %errorlevel%

如果您希望 errorlevel 的值传播到您的批处理文件之外

If you want the value of the errorlevel to propagate outside of your batch file

if %errorlevel% neq 0 exit /b %errorlevel%

但是如果这是在 for 中，它会变得有点棘手.你需要更多类似的东西:

but if this is inside a for it gets a bit tricky. You'll need something more like:

setlocal enabledelayedexpansion
for %%f in (C:Windows*) do (
    same-executable-over-and-over.exe /with different "parameters"
    if !errorlevel! neq 0 exit /b !errorlevel!
)

您必须在每个命令之后检查错误.在 cmd.exe/command.com 批处理中没有全局的on error goto"类型的构造.我还根据 CodeMonkey 更新了我的代码，尽管我从未在任何批量黑客攻击中遇到过负面错误级别在 XP 或 Vista 上.

You have to check the error after each command. There's no global "on error goto" type of construct in cmd.exe/command.com batch. I've also updated my code per CodeMonkey, although I've never encountered a negative errorlevel in any of my batch-hacking on XP or Vista.
