You cannot pass Booleans to a shell script.  CMD shell does not support Boolean, obects or arrays.  It can only receive strings.

c:\batchfile.bat $true $false

batchfile.bat  =
@echo %1
@echo %2

I need to use Invoke-Item to call batchfile.bat but it only works without parameters. i.e.

PS C:\ Invoke-Item C:\batchfile.bat

ok but got error below when add string parameters:

PS C:\ Invoke-Item C:\batchfile.bat abc 123
Invoke-Item : A positional parameter cannot be found that accepts argument 'abc'.
At line:1 char:1

• Invoke-Item C:\temp\echo.bat abc 123

You do NOT need Invoke-Item.  Invoke-Item is not used for batch files.  Just execute the batch file as I posted above.  It works just like I posted.  Look at the image.

To invoke a external command you need to use invoke-expression.

For example

$result = invoke-expression "c.bat param1 param2"

There is no need to use invoke when running a batch file or script.  PowerShell is designed to run those without any help.  Invoke-Item is used to open a document in its program and Invoke-Expression is used when you have a need to evaluate a complex text expression.

Thank you all for reply. I have a special need for this: as soon as launching batchfile.bat, I need to continue execute next scripts without wait. It seems only Invoke-Item can do that. Others have to wait to finish the batch file execution before continue, like Invoke-Expression, Invoke-Command or direct run the batch.. Thanks.

You cannot pass parameters with Invoke-Item.

Use Start-Process for that.

** Start-Process c:\batchfile.bat -Args $true,$false**
