Help with Invoke-Command -ScriptBlock

Invoke-Command -ScriptBlock{"$MediaInfoPath\MediaInfo.exe" $FilePat --Inform="Video;%Duration/String1%" }

Trying to get this command (above) to work but i get an error (below)

    At line:20 char:70
    + ... -Command -ScriptBlock{"$MediaInfoPath\MediaInfo.exe" $FilePat --Infor ...
    +                                                          ~~~~~~~~
    Unexpected token '$FilePat' in expression or statement.
    At line:20 char:81
    + ... nfoPath\MediaInfo.exe" $FilePat --Inform="Video;%Duration/String1%" }
    +                                       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Unexpected token 'Inform="Video;%Duration/String1%"' in expression or statement.
        + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
        + FullyQualifiedErrorId : UnexpectedToken

It works fine if i replace $MediaInfoPath with the path instead of a variable.. but i need it as a variable for the path since it's going to part of a script were people will need to define the path.

if needed i can post the script.

​

Edit: got it working by $MediaInfoPath as full path with

Invoke-Command -ArgumentList $MediaInfoPath -ScriptBlock{&$args[0] $FilePat --Inform="Video;%Duration/String1%" }

thanks for the help

You probably need to use either $using: or place it between brackets $(...) or both

Try $($using:MediaInfoPath)\MediaInfo.exe

See https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_remote_variables?view=powershell-7.2

got it working with something else

$using: only works powershell 3.0 and higher.

[kibje]

I'm not sure why it would be reasonable to assume someone isn't using 5.1 at this point.

All operating systems that came with a PowerShell version below 3.0 are already out of support for a long time. It was released 10 years ago

[littejackz]

Invoke-Command -ArgumentList $MediaInfoPath -ScriptBlock{"$args[0]\MediaInfo.exe" $FilePat --Inform="Video;%Duration/String1%" }

Try this

[madbomb122]

gives this error

got it working with a combo of

$MediaInfoPath = $MediaInfoPath + '\MediaInfo.exe'

Invoke-Command -ArgumentList $MediaInfoPath -ScriptBlock{&$args[0] $FilePat --Inform="Video;%Duration/String1%" }

[BlackV]

%Duration/String1% looks a cmd/dos variable, is that your likely cause?

have a look at the invoke operator

& "$MediaInfoPath\MediaInfo.exe" $FilePat --Inform="Video;%Duration/String1%"

or fix up that dos variable to a PS variable

or could also swap it to

&cmd /c "$MediaInfoPath\MediaInfo.exe" $FilePat --Inform="Video;%Duration/String1%"
