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 here. I am following the steps from it, though there are errors.
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).
