New cmdlets

Two other useful cmdlets included in PowerShell V4 are:

• Get-FileHash: Creates a hash value from a given file or binary value. This is useful for quickly determining whether files have changed or for finding duplicate files (that have different file names)
• Test-NetConnection: Diagnoses a network connection and provides helpful troubleshooting information. This cmdlet is described in more detail in Chapter 8, Managing Windows Network Services.
