处理具有相同前缀的相同文件 [英] processing same files with same prefix

问题描述

我的dir.lst如下： 

************************ * 

wady0_Hold.out.new 

wady0_Post.out.new 

wady2_Hold.out.new 

wady2_Post.out.new 

wady3_Post.out.new 

wady4_Hold.out.new 







但是我可以看到新创建的文件是在具有相同名称的旧文件上创建的。这违反了上面写的语法???? 

My dir.lst as like this : 
************************* 
wady0_Hold.out.new 
wady0_Post.out.new 
wady2_Hold.out.new 
wady2_Post.out.new 
wady3_Post.out.new 
wady4_Hold.out.new 



But I can see that the new created files are created over the old ones with the same names . That is against the syntax written above ???? 

dir /b %folder%\*.out.new > dir1.lst 

@echo off 
for /f "tokens=1,* delims=_" %%a in (dir1.lst) do ( 
   echo %%a 
   ::for missing pairs 
   if not exist %folder%\%%a_Post.out.new copy nul %folder%\%%a_Hold.out.new 
   if not exist %folder%\%%a_Hold.out.new copy nul %folder%\%%a_Post.out.new 
    
   pause "" 
) 

推荐答案

我怀疑你无意中越过了你的文件名。试试这个：

I suspect you inadvertently crossed over your file names. Try this:

   if not exist %folder%\%%a_Post.out.new copy nul %folder%\%%a_Post.out.new 
   if not exist %folder%\%%a_Hold.out.new copy nul %folder%\%%a_Hold.out.new
