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?


当前回答

对于使用循环获取所有参数,并且是纯批处理:

注意事项:用于不带:?*&<>


@echo off && setlocal EnableDelayedExpansion

for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!")

:: write/test these arguments/parameters ::
for /l %%l in (1 1 !_cnt!)do echo/ The argument n:%%l is: !_arg_[%%l]!

goto :eof 

你的代码已经准备好在需要的地方用参数号做一些事情,比如……

@echo off && setlocal EnableDelayedExpansion

for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!"

echo= !_arg_[1]! !_arg_[2]! !_arg_[2]!> log.txt

其他回答

获取脚本中所有参数的方法如下:

@ECHO off
ECHO The %~nx0 script args are...
for %%I IN (%*) DO ECHO %%I
pause

%*似乎包含传递给脚本的所有参数。

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

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。
