How to pass multiple params in batch?
提问by IAdapter
In my batch file I want to pass multiple parameters to some other application.
在我的批处理文件中，我想将多个参数传递给其他一些应用程序。
Now I do it
现在我做到了
app.exe %1 %2
and it can only pass two parameters, but I want to pass all the parameters that are passed to the batch(I would rather not write %1 %2 %3 %4 ...)
它只能传递两个参数，但我想传递所有传递给批处理的参数（我宁愿不写%1 %2 %3 %4 ...）
Is there any magic way to do it?
有什么神奇的方法可以做到吗？

There is a magic way! I knew it, but I could not remember it.
有一个神奇的方法！我知道，但我想不起来了。

Another way is to use one double quoted parameter. When calling the other application, you just use the %~Ndevice on the command line to remove the quotes.
另一种方法是使用一个双引号参数。调用其他应用程序时，您只需使用%~N命令行上的设备来删除引号。
If some parameters you intend to pass to the application are themselves double-quoted, those quote chars must be repeated twice.
如果您打算传递给应用程序的某些参数本身是双引号的，则这些引号字符必须重复两次。
Here's an illustration script that uses the first parameter as the application's name and the second as a combined parameter list to pass to the application:
这是一个插图脚本，它使用第一个参数作为应用程序的名称，将第二个参数用作传递给应用程序的组合参数列表：
@ECHO OFF
CALL %1 %~2
Here are examples of calling the script for different cases (pass one parameter or several parameters or quoted parameters).
以下是针对不同情况调用脚本的示例（传递一个参数或多个参数或引用参数）。
Pass 1 parameter to the app:
C:\>mybatch.bat app.exe "app_param" C:\>mybatch.bat app.exe app_paramPass several parameters:
C:\>mybatch.bat app.exe "app_param1 app_param2 app_param3"Pass a parameter that includes spaces (and so must be quoted):
C:\>mybatch.bat app.exe """parameter with spaces"""A combined example: some parameters are with spaces, others aren't:
C:\>mybatch.bat app.exe "param_with_no_spaces ""parameter with spaces"" another_spaceless_param"
将 1 个参数传递给应用程序：
C:\>mybatch.bat app.exe "app_param" C:\>mybatch.bat app.exe app_param传递几个参数：
C:\>mybatch.bat app.exe "app_param1 app_param2 app_param3"传递一个包含空格的参数（因此必须被引用）：
C:\>mybatch.bat app.exe """parameter with spaces"""一个组合示例：一些参数带有空格，而另一些则没有：
C:\>mybatch.bat app.exe "param_with_no_spaces ""parameter with spaces"" another_spaceless_param"

You could use the SHIFTprompt and loop through the arguments. Here is a demonstrative example where you would replace the final ECHO prompt with a prompt to load your application.
您可以使用SHIFT提示并遍历参数。下面是一个演示示例，您可以用加载应用程序的提示替换最终的 ECHO 提示。
@ECHO OFF
SET PARAMS=
:_PARAMS_LOOP
REM There is a trailing space in the next line; it is there for formatting.
SET PARAMS=%PARAMS%%1
ECHO %1
SHIFT
IF NOT "%1"=="" GOTO _PARAMS_LOOP
ECHO %PARAMS%
PAUSE
This may be useful if you need some sort of dynamic parameter counting, or if you want to disallow a certain parameter.
如果您需要某种动态参数计数，或者您想禁止某个参数，这可能很有用。
