将“集合”转换为小写

我正在处理一个要求输入昵称（但要大写）的 .bat 文件

set /p nickname="Please enter your uppercase name!:

我想知道我是否可以让蝙蝠存储原始（大写）昵称和全部小写昵称。

所以我可以这样做

%nickname%\files\avatar\1.png

或者

%nickname_lowercase%\files\avatar\1.png

我不想要求用户输入小写的昵称，我只想将用户输入的内容转换为小写并将其存储在“集合”或类似的东西中。这有点复杂，如果我无法解释，请原谅。

答案1

如何将变量的内容转换为小写？

使用以下批处理文件：

SETLOCAL ENABLEDELAYEDEXPANSION
set /p nickname="Please enter your uppercase name!:
rem save the name, use "s in case there are space in the name
set "_UpperNick=nickname"
call LoCase nickname
set "_LowerNick=nickname"
echo _UpperNick
echo _LowerNick
ENDLOCAL
GOTO:EOF

:LoCase
:: Subroutine to convert a variable VALUE to all lower case.
:: The argument for this subroutine is the variable NAME.
SET %~1=!%~1:A=a!
SET %~1=!%~1:B=b!
SET %~1=!%~1:C=c!
SET %~1=!%~1:D=d!
SET %~1=!%~1:E=e!
SET %~1=!%~1:F=f!
SET %~1=!%~1:G=g!
SET %~1=!%~1:H=h!
SET %~1=!%~1:I=i!
SET %~1=!%~1:J=j!
SET %~1=!%~1:K=k!
SET %~1=!%~1:L=l!
SET %~1=!%~1:M=m!
SET %~1=!%~1:N=n!
SET %~1=!%~1:O=o!
SET %~1=!%~1:P=p!
SET %~1=!%~1:Q=q!
SET %~1=!%~1:R=r!
SET %~1=!%~1:S=s!
SET %~1=!%~1:T=t!
SET %~1=!%~1:U=u!
SET %~1=!%~1:V=v!
SET %~1=!%~1:W=w!
SET %~1=!%~1:X=x!
SET %~1=!%~1:Y=y!
SET %~1=!%~1:Z=z!
GOTO:EOF

来源批处理文件 - 如何...将字符串转换为大写或小写

答案2

对于预测字符集，此子字符串Set !var:A=a!有效，并且只适用于预定义子字符串在/。

对于这种类型的任务，为什么不寻求一些帮助这使得使用非常规口音和辅音成为可能è, È, ä, Ä, ñ, Ñ, ç, Ç 等。

其中/将产生代码，它将在运行时被编译并执行....

解决了可能的用户输入问题，其中序列带有重音，并且元音/辅音与常规的元音/辅音不同[阿兹]和/或[亞洲]

注意：- 还可与带空格的昵称和/或撰写名字

  • 输入的输出 ==To Up Lower 
 Please enter nickname: To Up Lower

Your input nickname is: To Up Lower

这ToUpLower.cs 没有转义的代码：

 using System; namespace SUQ1522019 {class Program {static void Main(string[] args) {
 if (args.Length==2 && args[0].ToLower()=="-l") {Console.WriteLine(args[1].ToLower());} 
 if (args.Length==2 && args[0].ToLower()=="-u") {Console.WriteLine(args[1].ToUpper());}}}}

这ToUpLower.cs 没有转义和缩进的代码：

using System
namespace SUQ1522019 
{
   class Program 
   {
      static void Main(string[] args)
      {
         if (args.Length==2 && args[0].ToLower()=="-l") 
         {
            Console.WriteLine(args[1].ToLower());
         } 

         if (args.Length==2 && args[0].ToLower()=="-u") 
         {
            Console.WriteLine(args[1].ToUpper());
         }
      }
   }
}
  • 这代码是编译/测试在csc.exe版本：
c:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe
c:\Windows\Microsoft.NET\Framework\v3.5\csc.exe
c:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe
c:\Windows\Microsoft.NET\Framework64\v2.0.50727\csc.exe
c:\Windows\Microsoft.NET\Framework64\v3.5\csc.exe
c:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe
  • 这是命令行习惯编译这代码： 
c:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe /t:exe /out:"%tmp%\ToUpLower.exe" "%tmp%\ToUpLower.cs" /platform:anycpu /unsafe+ /w:0 /o /nologo
  • ToUpLower.exe用法 上部至 -> 下部 
ToUpLower.exe -l STRING 

:: if have space, use quote:

ToUpLower.exe -l "THIS STRING" 

:: or ..

ToUpLower.exe -L STRING

:: if have space, use quote:

ToUpLower.exe -L "THIS STRING"

  • ToUpLower.exe用法 下至 -> 上

ToUpLower.exe -u string

:: if have space, use quote:

ToUpLower.exe -u "this string"

:: or ..

ToUpLower.exe -U string

:: if have space, use quote:

ToUpLower.exe -U "this string"

保持ToUpLower.exe， 消除echo/从copy 命令：

回声/>nul 2>nul 复制“％tmp％\ToUpLower.exe” “。”
  • 此命令行将复制ToUpLower.exe从%temp%与你的 bat 运行所在的文件夹相同。

编程指南 C#：

  • 编辑：此代码将按以下顺序使用找到的第一个 .Net Framework 编译 C# 源代码： 
c:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe
c:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe
c:\Windows\Microsoft.NET\Framework\v3.5\csc.exe
c:\Windows\Microsoft.NET\Framework64\v3.5\csc.exe
c:\Windows\Microsoft.NET\Framework\v2.0.50727\csc.exe
c:\Windows\Microsoft.NET\Framework64\v2.0.50727\csc.exe

  • 第二种选择是添加/加入这ToUpLower.exe可执行文件batch文件，使用base64字符串和运行时解码。

    你可以使用%__APPDIR__%Certutil.exe，适用于 Windows。

注意：- 还可与带空格的昵称和/或撰写名字

抱歉我的水平有限英语

答案3

将文本转换为大写：（字符限制 255）

for /f "tokens=2 delims=-" %i in ('find "" "lower case text" 2^>^&1') do set i=%i& echo !i:~1!

转换为小写：（字符限制 255）

type nul > "UPPER CASE"
dir /l /b "UPPER CASE"

或者

md al & cd al
echo:> "SOME LONG FILENAME in here"
dir /l /b

更改整个文件的大小写：

set case=upper
set file=line.txt

if exist out.txt del out.txt

for %i in (%file%) do set n=%~zi
fsutil file createnew A %n% >nul
fc /b A %file% | more +1 > B

type nul > A
for /f "tokens=3" %i in (B) do (

if %case%==lower (
if 0x%i gtr 0x40 (if 0x%i lss 0x5b (set /a a=0x%i+0x20 >nul) else set /a a=0x%i >nul) else set /a a=0x%i >nul
)
if %case%==upper (
if 0x%i gtr 0x60 (if 0x%i lss 0x7b (set /a a=0x%i-0x20 >nul) else set /a a=0x%i >nul) else set /a a=0x%i >nul
)
cmd /c exit /b !a! & set hex=!=exitcode:~-2!& set /p=!hex! <nul

) >> A

certutil -decodehex A out.txt

del A & del B

笔记：

exitcodeASCII&forfiles可以完成相同的任务，而且可能更快，使用更多代码来处理 TAB、SPACE、CR 和 LF。

在 Win 10 cmd 上测试
