Executing CMD Command from a PowerShell Script

Question

I have seen many similar questions but none of them is related to the execution of a CMD command such as ipconfig from a PS script (.ps1).

If you type those commands on the PS console they work fine but once on a script they don't, below you can see an example:

PS C:\Users\TestQro> adb devices
List of devices attached

PS C:\Users\TestQro> adb devices | Select-String -Quiet List
True

returns True because the Select-String finds the word "List" in the response of the command "adb devices" which is the expected behavior. But if I go and put the same command into a .ps1 script file PS answers when running:

PS C:\TesterInfo> ./TunnerApp.ps1

cmdlet Write-Output at command pipeline position 1
Supply values for the following parameters: InputObject[0]:

How should I type the normal CMD commands inside of a script? Why is it waiting for parameters on script but right in the console it works fine?

Answer 1

Based on your output there

PS C:\TesterInfo> ./TunnerApp.ps1

cmdlet Write-Output at command pipeline position 1
Supply values for the following parameters: InputObject[0]:

It looks like you have a Write-Output statement somewhere in your PowerShell script that does not have any input. Look for an empty Write-Output statement somewhere

Answer 2

What you're referring to as CMD commands are actually executables in the Windows or System32 folders (or some other PATH environment variable path). As such, you can call them like you would any executable using the call operator:

& "$Env:SystemRoot\System32\IPCONFIG.exe"
