我想找到一个Windows批处理对应Bash的$@,它持有传递到脚本的所有参数的列表。

还是要我费心去换班?

我发现下次你需要查这些资料的时候。你不需要打开浏览器,只需要输入call /?在你的CMD,你会得到它:

%* in a batch script refers to all the arguments (e.g. %1 %2 %3
    %4 %5 ...)

Substitution of batch parameters (%n) has been enhanced.  You can
now use the following optional syntax:

    %~1         - expands %1 removing any surrounding quotes (")
    %~f1        - expands %1 to a fully qualified path name
    %~d1        - expands %1 to a drive letter only
    %~p1        - expands %1 to a path only
    %~n1        - expands %1 to a file name only
    %~x1        - expands %1 to a file extension only
    %~s1        - expanded path contains short names only
    %~a1        - expands %1 to file attributes
    %~t1        - expands %1 to date/time of file
    %~z1        - expands %1 to size of file
    %~$PATH:1   - searches the directories listed in the PATH
                   environment variable and expands %1 to the fully
                   qualified name of the first one found.  If the
                   environment variable name is not defined or the
                   file is not found by the search, then this
                   modifier expands to the empty string

The modifiers can be combined to get compound results:

    %~dp1       - expands %1 to a drive letter and path only
    %~nx1       - expands %1 to a file name and extension only
    %~dp$PATH:1 - searches the directories listed in the PATH
                   environment variable for %1 and expands to the
                   drive letter and path of the first one found.
    %~ftza1     - expands %1 to a DIR like output line

In the above examples %1 and PATH can be replaced by other
valid values.  The %~ syntax is terminated by a valid argument
number.  The %~ modifiers may not be used with %*

%*似乎包含传递给脚本的所有参数。

你可以使用命令,以获得参数列表。

帮助:For /? 帮助:Setlocal /?

这是我的方法=

@echo off
::For Run Use This = cmd /c ""Args.cmd" Hello USER Scientist etc"
setlocal EnableDelayedExpansion
set /a Count=0
for %%I IN (%*) DO (
 Echo Arg_!Count! = %%I
 set /a Count+=1 
)
Echo Count Of Args = !Count!
Endlocal

不需要Shift命令。

下面的代码模拟了一个数组('params')——接受脚本接收到的参数,并将它们存储在变量params_1 ..Params_n,其中n=params_0=数组元素的个数:

@echo off

rem Storing the program parameters into the array 'params':
rem Delayed expansion is left disabled in order not to interpret "!" in program parameters' values;
rem however, if a parameter is not quoted, special characters in it (like "^", "&", "|") get interpreted at program launch
set /a count=0
:repeat
    set /a count+=1
    set "params_%count%=%~1"
    shift
    if defined params_%count% (
        goto :repeat
    ) else (
        set /a count-=1
    )    
set /a params_0=count

rem Printing the program parameters stored in the array 'params':
rem After the variables params_1 .. params_n are set with the program parameters' values, delayed expansion can
rem be enabled and "!" are not interpreted in the variables params_1 .. params_n values
setlocal enabledelayedexpansion
    for /l %%i in (1,1,!params_0!) do (
        echo params_%%i: "!params_%%i!"
    )
endlocal

pause
goto :eof

如果参数在包含空格的引号中,%*将无法正确工作。 我发现的最佳解决方案是使用一个连接所有参数的循环:https://serverfault.com/a/22541

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

:done
(use %args% here)
