Adding members to a distribution group from an external file

When working in large or complex environments, performing bulk operations is the key to efficiency. Using PowerShell's core cmdlets such as Get-Content and Import-CSV, we can easily import external data into the shell and use this information to perform bulk operations on hundreds or thousands of objects in a matter of seconds. Obviously, this can vastly speed up the time we spend on routine tasks and greatly increase our efficiency.
