Batch file 更改文件名Case DOS批处理文件

我已经计划使用下面的代码使用DOS批处理文件将文件名的大小写改为小写，但是我想知道是否有人可以帮助我添加包含代码以大写每个文件名的第一个字母

不确定您的代码是否是最佳（可能是）解决方案，但我没有更改：

@echo off
setlocal enableDelayedExpansion
for %%f in (*.*) do (
set "filename=%%~nf"
set filename=!filename:A=a!
set filename=!filename:B=b!
set filename=!filename:C=c!
set filename=!filename:D=d!
set filename=!filename:E=e!
set filename=!filename:F=f!
set filename=!filename:G=g!
set filename=!filename:H=h!
set filename=!filename:I=i!
set filename=!filename:J=j!
set filename=!filename:K=k!
set filename=!filename:L=l!
set filename=!filename:M=m!
set filename=!filename:N=n!
set filename=!filename:O=o!
set filename=!filename:P=p!
set filename=!filename:Q=q!
set filename=!filename:R=r!
set filename=!filename:S=s!
set filename=!filename:T=t!
set filename=!filename:U=u!
set filename=!filename:V=v!
set filename=!filename:W=w!
set filename=!filename:X=x!
set filename=!filename:Y=y!
set filename=!filename:Z=z!
ren "%%~nxf" "!filename!%%~xf"
)

for %%l in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do (
    for %%f in (*.*) do (
        set filename=%%~nf
        if /i "!filename:~0,1!" EQU "%%~l" (
            ren "%%~nxf" "%%l!filename:~1!%%~xf"
        )
    ) 
)
endlocal
popd

您可以充分利用子字符串替换不区分大小写的事实，即在源字符中忽略大小写，但在替换字符中保留大小写：

@echo off
setlocal EnableDelayedExpansion

rem Capitalize.bat: Change file names with first letter uppercase, the rest 

lowercase

for %%f in (*.*) do (
   set "filename=%%~Nf"
   rem Change all letters to lowercase
   for %%a in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do (
      set "filename=!filename:%%a=%%a!"
   )
   rem Change first letter to uppercase
   set "letter=!filename:~0,1!"
   for %%A in (A B C D E F G H I J K L M N O P Q R S T U V W X Y Z) do (
      set "letter=!letter:%%A=%%A!"
   )
   ren "%%f" "!letter!!filename:~1!%%~Xf"
)

嗨，非常感谢你的帮助。是的，代码不是最优的，但我理解它！然而，现在我看到了您的代码，我将考虑使其更高效。再次感谢。乔治：-）我喜欢你的编码，阿奇尼-你经常有非常优雅的方法，尽管有时很难破译。我只是想提一下，

角色将打破这个。谢谢，狐狸！是的，
的问题与往常一样，但我不想提及它，因为大多数用户都没有这种情况。如果有人有这个问题，并要求解决，那么是时候解释一下环境切换技术了
