如果存在，请批量检查是否区分大小写 [英] if exist check with case sensitive in batch

问题描述

我需要检查给定文件是否存在，并区分大小写，在我运行脚本的位置中存在out.txt(均为小写字母)文件.

I need to check whether the given file is exist or not with case sensitive, out.txt(all are small letters) file is present in location where i running the script.

代码:

Case1:
filename=out.txt
 if exist %filename% (
    echo file exist...
) else echo File doesn't exist...

Case2:
filename=OUT.TXT
if exist %filename% (
    echo file exist...
) else echo File doesn't exist...

对于这两种情况，它都显示文件存在...输出.但是我需要检查是否区分大小写.它应该显示OUT.TXT的文件不存在"消息.

For both case it showing file exist... output. But i need to check with case sensitive. It should show "File doesn't exist" msg for OUT.TXT

预先感谢

推荐答案

从参数中获取文件名:

@echo off 
dir /b /a-d "%~1"|find "%~1" >nul
if %errorlevel% == 0 (echo found) else (echo fail)

dir实际上不区分大小写-但是find是...

diris in fact not case sensitive - but find is...
