在Windowsbatch file中运行以下代码时，除了包含星号的string外，其他所有内容都将被忽略。 通过数字检查传递的参数（即echo(%~6 ）我可以看到星号 – 只有当传递给FOR循环，我有一个问题：
@echo off setlocal enableextensions enabledelayedexpansion call:Concat cmd "this is a demo" " of concat functionality." " Hopefully it will work;" " but it doesn't when I pass an" " * asterisk" " character" echo !cmd! @goto:end @goto:eof :Concat ::Concatenates a given list of strings without including their quotes ::1 - output variable ::2* - strings to concat echo(%* set /a xx=0 set Concat_tempFlag=0 set Concat_temp= for %%A in (%*) do ( set /a xx=!xx!+1 echo !xx! - %%A if !Concat_tempFlag!==1 ( set Concat_temp=!Concat_temp!%%~A ) else ( set Concat_tempFlag=1 ) ) set "%~1="%Concat_temp%"" @goto:eof :End echo(Bye exit /b 0
我尝试for /F (tokens=*) %%A in ('echo(%*') do (如在这里build议： 批处理循环与星号 （及其变体），但没有运气。提前。
在这里找到解决方案： 我需要使用本地Windows命令匹配或替换批处理环境变量中的星号*。 这可能吗？

您提供的链接导致正确的答案：
在正常（无/ F选项）FOR命令的集合（它们总是更改为文件名）中没有办法保留星号（也不是问号）。 您需要在FOR / F命令中分隔参数。 如果您还想在FOR循环中处理每个参数，则第二个FOR不能位于同一个上下文中，因此您必须调用子例程来更改上下文
