Filtering arguments in windows batch file -

-

is possible filter list of arguments in windows batch file?

assuming called like:

file.cmd arg1 --unwanted arg3

it should call other executable (hardcoded) without argument string --unwanted:

some.exe arg1 arg3

i know name of argument, can passed argument in list. may not exist on argument list, , arguments should passed unmodified. number of arguments may vary.

more examples (what's called -> should called in result)

file.cmd arg1 arg2 -> some.exe arg1 arg2 file.cmd --unwanted -> some.exe file.cmd --unwanted arg2 -> some.exe arg2 file.cmd arg1 --unwanted -> some.exe arg1

moving unix shell scripting windows batch files black magic me :)

@echo off setlocal enableextensions  if "%1"=="sotest" (     rem tests...     call file.cmd arg1 --unwanted arg3     call file.cmd arg1 arg2     call file.cmd --unwanted     call file.cmd --unwanted arg2     call file.cmd arg1 --unwanted     goto :eof )  set params= :nextparam if "%~1"=="--unwanted" (shift&goto nextparam) if not "%~1"=="" (set "params=%params%%1 "&shift&goto nextparam)  echo.%*^>^>%params%

this prints:

arg1 --unwanted arg3>>arg1 arg3 arg1 arg2>>arg1 arg2 --unwanted>> --unwanted arg2>>arg2 arg1 --unwanted>>arg1

edit:

@echo off setlocal enableextensions  if "%~1"=="sotest" (     rem tests...     call file.cmd arg1=foo --unwanted arg3=bar     call file.cmd arg1 arg2     call file.cmd --unwanted     call file.cmd --unwanted arg2     call file.cmd arg1 --unwanted     call file.cmd "arg1" --unwanted "arg3"     call file.cmd "arg1=foo" --unwanted arg3="bar"     goto :eof )  set var=0 set params= :nextparam set /a var=%var% + 1 /f "tokens=%var% delims= " %%a in ("%*") (     if not "%%~a"=="--unwanted" set "params=%params%%%a "     goto nextparam )  echo.%*^>^>%params%

prints

arg1=foo --unwanted arg3=bar>>arg1=foo arg3=bar arg1 arg2>>arg1 arg2 --unwanted>> --unwanted arg2>>arg2 arg1 --unwanted>>arg1 "arg1" --unwanted "arg3">>"arg1" "arg3" "arg1=foo" --unwanted arg3="bar">>"arg1 foo" arg3="bar"

meaning "arg1=foo" broken, can switch loop for /f "tokens=%var% delims= " %%a in ('echo.%*') ( working, breaks arg1=foo , arg3="bar"

this known problem batch files, once start messing strings things going screwed in configuration since there character going mess things (%,!,",^,&,|,<,>,space etc)
