cmd - 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).
