Batch file 如何在for命令-Win批处理文件中将变量（其值）用作标记

所以情况是这样的。。。我有两个嵌套的if语句，然后在它们内部有一个循环（使用GoTo命令和一个递增变量-for-loop-simulation:D）。正如您可能知道的，要将新值分配给（if语句）括号内的变量，您必须使用delayedexpansion。此外，要在for命令中使用变量，您必须将百分比标记加倍，如so%%。我想将for/f命令中的标记设置为我想要的变量值。问题是把感叹号加倍没有效果。我也试过各种方法。。。就像使用引号，转义那些引号，使用引号替代品，但这一切都是徒劳的。如果你能以任何方式帮助我，那就太好了，因为我想不出任何事情：（.提前谢谢大家

如果这没有意义，下面是代码：

@echo off
set FilePath=test.bat
set RefreshRate=3
setlocal enabledelayedexpansion enableextensions
:GetData
if defined FilePath (
if exist "%FilePath%" (
:GetLines
cls
:: This is how I find out how many lines there is in the file
set "cmd=findstr /R /N "^^" "%FilePath%" | find /C ":""
for /f %%a in ('!cmd!') do set Lines=%%a
:ShowCode
cls
set LineNum+=1
if ""!LineNum!"" GTR ""!Lines!"" GoTo Refresh

::THIS IS THE MAIN PROBLEM
for /f "tokens=%%LineNum%% delims=$" %%b in ("%FilePath%") do (

set Line%LineNum%=%%b
echo !LineNum!. | !Line%LineNum%!
GoTo ShowCode
)
)
)
:Refresh
ping localhost -n %RefreshRate% >nul
GoTo GetData

很抱歉，我没有足够的时间让它更具可读性，但它应该让整个事情更清楚一些。

令牌属性不在括号中，它们在引号中，无论如何都是错误的。它是第n到第n个分隔的术语

类型

例如

首先：不要在

（）

括号内的代码块中使用

：：备注

注释或

：标签

。可以在后面提供的脚本输出中编码的

标签.bat

脚本中找到有害性证明

在下一个脚本中，特定纯文本文件的非空行（参见

set“FilePath=labels.bat”

）保存到伪数组

LineAAA

，其中index

AAA

=行号。根据您的问题，我不知道它是否脱离主题，但可以提供一些有用的线索

@echo off
setlocal enabledelayedexpansion enableextensions
cls
set line
set "FilePath=labels.bat"
set /A "RefreshRate=3"
:GetData
if not defined FilePath (
  echo %%FilePath%% not defined
  goto :eof
)
if not exist "%FilePath%" (
  echo %FilePath% does not exist
  goto :eof
  rem  following 'else' (sub)statement seems to be superabundant 
) else (
    rem GetLines
    rem This is how I find out how many lines there is in the file
    set "cmd=findstr /R /N "^^" "%FilePath%" | find /C ":""
    for /f %%a in ('!cmd!') do set /A "Lines=%%a"
    set /A "LineNum=0"
    set "Line000=@rem %FilePath%"
    for /f "tokens=*" %%b in (%FilePath%) do (
      set /A "LineNum+=1"
      set "LineX=000000000!LineNum!"  
      set "LineX=!LineX:~-3!"  
      set "Line!LineX!=%%b"
    )
    call :Refresh
)
set line
rem pause
endlocal
goto :eof

:Refresh
  ping localhost -n %RefreshRate% | findstr /I "Packets: statistics"
  rem >nul
GoTo :eof

输出：

哦，这是一个输入错误：D，标记只能是一个标记-就像在第n个标记中一样，就像这里的一个示例：…无论如何，谢谢。哇！非常感谢。对我来说，它是否在主题上并不重要。这仍然是一个更容易的选择。我没有想到使用星号通配符作为标记，而不是整个循环和v可变程序。我明天早上试试……这是漫长的一天：D
