PowerTip: Determine If PowerShell Command Exists

Summary: Use Get-Help to determine if a Windows PowerShell command exists.

 How can I find if a Windows PowerShell command (cmdlet or function) exists in my version of Windows PowerShell?

 Use the Get-Help cmdlet. If Help returns, you can read about the command.
          If it does not return, follow up with Get-Command:

get-help my-coolfunction

get-command my-coolfunction
