使用＆QUOT调用时传递变量的批处理文件;调用＆QUOT;功能 [英] passing variable to a batch file when called using "call" function

问题描述

我想从另一个调用批处理文件的批处理文件，并希望将变量传递给它。可以说，我想从a.bat调用b.bat。我b.bat复制文件。因此，虽然从a.bat调用它，我想传递的目标文件夹b.bat的路径。结果
以及为b更加清晰，目标路径将用户B进入，所以将b存储在一个变量说'X'。我现在该如何传递路径？

解决方案

  REM --- a.bat ---
集/ p = TARGETPATH​​请输入目标路径：
叫b.bat％TARGETPATH​​％REM --- b.bat ---
回声复制到：％〜1
 

作为一种替代方法，你可以简单地使用％TARGETPATH​​％在b.bat：环境变量由子进程继承。但是传递一个明确的参数大概是从视图的灵活性和可支持性好点。

i want to call a batch file from another batch file and also want to pass a variable to it. lets say i want to call b.bat from a.bat. my b.bat copies files. so while calling it from a.bat , i want to pass the path of the destination folder to b.bat.
well to b more clear, the destination path will b entered by user, so it will b stored in a variable say 'x'. how do i pass the path now?

解决方案

rem --- a.bat ---
set /p TargetPath=Please enter destination path: 
call b.bat "%TargetPath%"

rem --- b.bat ---
echo Copying to: %~1

As an alternative, you can simply use %TargetPath% in b.bat: environment variables are inherited by subprocesses. But passing a parameter explicitly is probably better from the flexibility and supportability point of view.
