將“set”轉換為小寫

我正在處理一個需要暱稱（但要大寫）的 .bat 文件

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

我想知道我是否可以使蝙蝠存儲原始（大寫）暱稱和全小寫暱稱。

所以我可以這樣做

%nickname%\files\avatar\1.png

或者

%nickname_lowercase%\files\avatar\1.png

我不想向用戶詢問小寫暱稱，我只是希望它將用戶輸入的內容轉換為小寫並將其儲存在「集合」或其他內容中。有點複雜，抱歉沒能解釋清楚。

答案1

如何將變數的內容轉換為小寫？

使用以下批次檔：

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

來源批次檔 - 如何...將字串轉換為大寫或小寫

答案2

對於預測字元集，該子字串Set !var:A=a!有效，並且僅與預定義子字串在/。

對於此類任務，為什麼不尋求一些幫助，這使得可以使用非常規的重音和輔音è、È、ä、ä、ñ、Ñ、ç、Ç 等。

哪裡的/將生成程式碼，它將在運行時編譯並執行......

解決了可能的用戶輸入，其中序列帶有重音並且元音/輔音與傳統的不同[阿茲]和/或[A_Z]

觀察：- 還與帶空格的暱稱和/或與寫名字

@echo off && setlocal EnableDelayedExpansion

echo/ >nul 2>nul copy "%tmp%\ToUpLower.exe" "." 
del /q /f "%tmp%\ToUpLower.*" >nul 2>nul && endlocal & goto :EOF
  • 輸入的輸出 ==To Up Lower 
 Please enter nickname: To Up Lower

Your input nickname is: To Up Lower
  Your input upcase is: TO UP LOWER
 Your input lowcase is: to up lower

這ToUpLower.cs 沒有轉義的程式碼：

 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());}}}}

這ToUpLower.cs 沒有轉義和縮排的程式碼：

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());
         }
      }
   }
}
  • 這代碼是編譯/測試在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
  • 這是命令列習慣編譯這代碼： 
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 上到 -> 下 
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"

為了保留ToUpLower.exe， 消除echo/從copy 命令:

迴聲/>nul 2>nul 複製“%tmp%\ToUpLower.exe”“。”
  • 該命令列將複製ToUpLower.exe從%temp%到運行bat的同一資料夾。

C# 程式設計指南：

  • 編輯：此程式碼將使用以下順序找到的第一個 .Net Framework 來編譯 C# 原始碼： 
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

  • 第二個選擇是新增/加入這ToUpLower.exe可執行於batch文件，使用64位基數字串和運行時解碼。

    您可以使用什麼%__APPDIR__%Certutil.exe，可在 Windows 上使用。

觀察：- 還與帶空格的暱稱和/或與寫名字

@echo off && setlocal EnableDelayedExpansion

抱歉我水平有限英語

答案3

將文字轉換為大寫：（字元限制 255）

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

轉換為小寫：（字元限制 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

若要更改整個檔案的大小寫：

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

筆記：

exitcodeASCII&forfiles可以完成相同的任務，而且可能更快，用更多的程式碼來處理 TAB、SPACE、CR 和 LF。
