Get-Service, Get-Module, Get-ChildItem are not being recognized in PowerShell

Question

I have been trying different command in Powershell but all of them are not working. Where might be the problem ?

I am unable to run even the command to check the version :

C:\Users\ams.ssh>$PSversionTable '$PSversionTable' is not recognized as an internal or external command, operable program or batch file.

C:\Users\ams.ssh>$PSversionTable.PSVersion '$PSversionTable.PSVersion' is not recognized as an internal or external command, operable program or batch file.

C:\Users\ams.ssh>Get-Host | Select-Object Version 'Get-Host' is not recognized as an internal or external command, operable program or batch file.

Answer 1

Those are command prompt errors. You're trying to run PowerShell commands from cmd.exe. A PowerShell error looks like this:

PS C:\...\keith>get-bob
get-bob : The term 'get-bob' is not recognized as the name of a cmdlet, function, script file, or
operable program. Check the spelling of the name, or if a path was included, verify that the path is
correct and try again.
