批处理参数:%1 之后的所有内容 [英] batch parameters: everything after %1

问题描述

重复:

• 是有没有办法指示批处理文件中的最后 n 个参数?
• 如何从第 N 个位置获取批处理文件参数?

澄清:我知道循环方法 - 这甚至在命令扩展之前就有效；我希望有一些有趣的和未记录的东西，比如 %~*1 或其他什么——就像那些记录在 http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/percent.mspx?mfr=true.

<小时>

在 Windows 批处理文件中(启用了所谓的命令扩展")，%1 是第一个参数，%2 是第二个参数，等等.%* 是连接的所有参数.

我的问题:例如，有没有办法在 %2 之后获取所有内容?

我找不到这样的东西，这对我正在做的事情会有帮助.

解决方案

我不确定是否有直接命令，但您始终可以使用简单的循环和移位来获取变量中的结果.类似的东西:

<前>@回声关闭设置 RESTVAR=转移:loop1如果 "%1"=="" 转到 after_loop设置 RESTVAR=%RESTVAR% %1转移转到循环 1:after_loop回声%RESTVAR%

如果有帮助，请告诉我！

• Is there a way to indicate the last n parameters in a batch file?
• how to get batch file parameters from Nth position on?

Clarification: I knew of the looping approach - this worked even before Command Extensions; I was hoping for something fun and undocumented like %~*1 or whatever - just like those documented at http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/percent.mspx?mfr=true.

---

In a Windows batch file (with the so called "Command Extensions" on), %1 is the first argument, %2 is the second, etc. %* is all arguments concatenated.

My question: is there a way to get everything AFTER %2, for example?

I couldn't find such a thing, and it would be helpful for something I'm working on.

解决方案

I am not sure if there is a direct command but you can always use a simple loop and shift to get the result in a variable. Something like:

@echo off
set RESTVAR=
shift
:loop1
if "%1"=="" goto after_loop
set RESTVAR=%RESTVAR% %1
shift
goto loop1

:after_loop
echo %RESTVAR%

Let me know if it helps!
