批量不能很好地工作。(Batch not working very well. IF EXIST)

批量不能很好地工作。(Batch not working very well. IF EXIST)

试着玩一些批处理。

@ echo off IF EXIST %CD%\Minecraft.exe Minecraft.exe IF NOT exist %CD%\Minecraft.exe wget.exe https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft.exe Minecraft.exe pause

我做错了什么？ 当我运行它时，CMD就会关闭。

Trying to play with some Batch.

@ echo off IF EXIST %CD%\Minecraft.exe Minecraft.exe IF NOT exist %CD%\Minecraft.exe wget.exe https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft.exe Minecraft.exe pause

What have I done wrong? CMD just closes when I run it.

最满意答案

我做错了什么？

if /?你可以阅读IF命令的帮助if /? 。

它解释了if期望全部在一条线上

@echo off IF EXIST %CD%\Minecraft.exe Minecraft.exe IF NOT exist %CD%\Minecraft.exe wget.exe https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft.exe Minecraft.exe pause

或者使用ELSE

@echo off IF EXIST %CD%\Minecraft.exe ( Minecraft.exe ) ELSE ( wget.exe https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft.exe Minecraft.exe ) pause

What have I done wrong?

You could read the help of the IF command if /?.

It explains that the if expects all on one line

@echo off IF EXIST %CD%\Minecraft.exe Minecraft.exe IF NOT exist %CD%\Minecraft.exe wget.exe https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft.exe Minecraft.exe pause

Or use the ELSE

@echo off IF EXIST %CD%\Minecraft.exe ( Minecraft.exe ) ELSE ( wget.exe https://s3.amazonaws.com/MinecraftDownload/launcher/Minecraft.exe Minecraft.exe ) pause
