Windows 批处理文件是否有 %* 结构?

Windows 批处理文件是否有 %* 结构?

在批处理文件中,我是否必须执行以下操作?

@echo off
call other.bat %1 %2 %3 %4 %5 %6 %7 %8 %9

答案1

Windows 批处理文件(自 Windows XP 起,但可能更早)支持该%*构造,它可以计算从 %1 开始的所有参数。

不幸的是,这不遵守SHIFT命令,因此以下命令不起作用:

@echo off
set EATEN=%1
shift

call other.bat %*

它仍会将第一个参数传递给第二个批处理文件。

答案2

您可以使用类似以下方法将所有参数收集在一起:

set args=%1
shift
:start
if [%1] == [] goto done
set args=%args% %1
shift
goto start

:done
(use %args% here)

无论有多少个参数,这都是有效的。

答案3

例如,如果您想跳过前 3 个参数并传递其余参数:

@echo off
for /f "tokens=1-3*" %%a in ("%*") do (
   set par1=%%a
   set par2=%%b
   set par3=%%c
   set therest=%%d
   )

call other.bat %therest%

参数中的引号可能有问题。
