PowerShell The term is not recognized as cmdlet function script file or operable program

Question

I am implementing a script in powershell and getting the below error. The sceen shot is there exactly what I entered and the resulting error.

At this path there is file Get-NetworkStatistics.ps1 which I got from Technet Gallery. I am following the steps from it, though there are errors.

Answer 1

You first have to 'dot' source the script, so for you :

. .\Get-NetworkStatistics.ps1 

The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted or set-ExecutionPolicy AllSigned see(the Execution Policy instructions).

Answer 2

For the benefit of searchers, there is another way you can produce this error message - by missing the $ off the script block name when calling it.

e.g. I had a script block like so:

$qa = {     param($question, $answer)     Write-Host "Question = $question, Answer = $answer" } 

I tried calling it using:

&qa -question "Do you like powershell?" -answer "Yes!" 

But that errored. The correct way was:

&$qa -question "Do you like powershell?" -answer "Yes!"
