当前目录不存在:批处理文件 [英] Current Directory does not exist: batch files

问题描述

最近，我一直在尝试使用批处理文件为我做一些重复的工作，并且检查当前目录中是否存在文件至关重要.过去，我经常使用批处理文件，但是现在使用的是新计算机，从Dropbox获取的旧批处理文件不起作用，我不确定为什么.考虑一个批处理脚本:

recently I have been trying to use batch files to do some repetitive work for me, and checking whether a file exist within a current directory is crucial. I have worked with batch files often in the past, but I am now using a new computer, and the old batch files I obtain from dropbox does not work, and I am unsure why. Consider a batch script:

@echo off
echo Build Verification...
if not exist "%cd%\build.bat" GOTO buildFail
echo Success!
pause
exit

:buildFail
echo Building of mod failed!
pause 
exit

build.bat在当前目录中确实存在，但这是cmd给我的:

build.bat DOES exist, in the current directory, but this is what the cmd gave me:

Build Verification...
The syntax of the command is incorrect.
Building of mod failed!
Press any key to continue...

对于为什么会发生这种情况感到困惑，我尝试了一些变化:

Baffled at why this would happen, I tried a few variation:

(如果动态目录有问题)

(In case dynamic directory has problems)

@echo off
echo Build Verification...
if not exist "%~dp0\build.bat" GOTO buildFail
echo Success!
pause
exit

:buildFail
echo Building of mod failed!
pause 
exit

但是它会产生相同的结果

But it yield same results

直接复制目录批发而不使用％dp〜0或％cd％也会产生相同的结果.

Directly copying the directory wholesale without using %dp~0 or %cd% also yields the same result.

通过将目录设置为变量也不起作用:

By setting the directory as a variable does not work either:

set randdir = "%cd%\build.bat"
if not exist "%randdir%" GOTO buildFail

但这是最奇怪的部分: 调用catch文件有效

But here is the weirdest part: Calling the catch file works

@echo off
echo Build Verification...
call "%cd%\build.bat"

这将导致build.bat的激活

This would result in the activation of build.bat

请帮助！

推荐答案

此处进行了一些小的修改:

Heres a small modification:

@Echo Off
SetLocal EnableExtensions
If /I Not "%__CD__%"=="%~dp0" PushD "%~dp0" 2>Nul||Exit/B 2
Echo=Build Verification...
If Not Exist "build.bat" GoTo buildFail
Echo=Success!
Timeout -1
Exit/B 0

:buildFail
Echo=Building of mod failed!
Timeout -1
Exit/B 1

请让我们知道它的进展情况.

Just let us know how it goes.
