calling powershell with arguments [SOLVED]

Hello everybody,

I been trying to call powershell with CheckExternalScripts module, if I call it like this (saw it in another thread) it works ok,

test_script=cmd /c echo scripts\powershell.ps1 | powershell.exe -command -

but if I want to pass an argument to the powershell script, like this (doesn't work, as expected, since is redirecting output and input) test_script=cmd /c echo scripts\powershell.ps1 $ARG1$ | powershell.exe -command - or test_script=cmd /c echo scripts\powershell.ps1 | powershell.exe -command -arg $ARG1$ -

it won't run. Is there any way to call powershell effectively with arguments?

thanks!

    Look at the "Wrapped Scripts" section in the latest version. It will "help you" with all that. 

     + Added new "script templating" thing to simplify adding scripts:
   Two new sections: [Script Wrappings] for adding templates and [Wrapped Scripts] for adding the scripts.
    %SCRIPT% is replaced with the script name
    %ARGS% is replaced with arguments.
     vbs=cscript.exe //T:30 //NoLogo scripts\wrapper.vbs %SCRIPT% %ARGS%
    and
     w_vbs=check_test.vbs /arg1:1 /arg2:1 /variable:1
    is the same as:
     w_vbs=cscript.exe //T:30 //NoLogo scripts\wrapper.vbs check_test.vbs /arg1:1 /arg2:1 /variable:1
 * Added correct syntax for VB scripts
 * Added correct syntax for powershell scripts

    There you just put: 

    [Wrapped Scripts]
check_test_ps1=check_test.ps1 arg1 arg2 $ARG1$

    The proper syntax (if you don't wanna use this) can be found in the other section mentioned: 

    cmd /c echo <SCRIPT> <ARGS>; exit($lastexitcode) | powershell.exe -command -

      Worked great. Thank you for your fast response! 

      [Script Wrappings]
ps1=cmd /c echo scripts\%SCRIPT% %ARGS%; exit($lastexitcode) | powershell.exe -command -

        Maybe i can piggy-back on this thread..

        What happens if powershell is getting only empty arguments, despite the script wrapper being active? 

        logparser=logparser_args.ps1 $arg1 $arg2

        This is my call for the powershell script and nsclient seems to loose the arguments that nagios is sending (I can see them when i run nsclient /test and allow_arguments=1 is set). Does the wrapper need a modification to work with multiple arguments or is just my call for the script wrong?

          Humm, $arg1 seems wrong think it whould be $ARG1$ or maybe $arg1$ note sure of the top of my head...

          But this is a simple string replacement so... Given:

          • script=foo
          • arguments=1 2 3 4

          Then this: 

          ps1=cmd /c echo scripts\%SCRIPT% %ARGS%; exit($lastexitcode) | powershell.exe -command -

          Will turn into this: 

          ps1=cmd /c echo scripts\foo 1 2 3 4; exit($lastexitcode) | powershell.exe -command -

          In your case though getting script and arguments set could be what breaks... but for instance: 

          bar=foo $ARG1$ $ARG2$ $ARG3$ $ARG4$

          called like so: 

          bar 1 2 3 4

          should translate to:

          • script=foo
          • arguments=1 2 3 4

          (ish)

            You are right, my own error put me into this place. After replacing $arg1 (which i just copied from the [Wrapped Scripts] of the nsc.ini without checking) with $ARG1$, it just works.

            Thank you for clearing that up, lets hope no one else falls into the trap of copy&paste.
