This post explains PowerShell cmdlets(commandlets).Scripting is easier when using PowerShell, you can access every method and property of every object. You have to use right shell to write the PowerShell commands.

Get-SpDatabase

To pass the results of above results to the shell admin command, use a pipeline between commands the command looks as below

Get-SpDatabase | Add-SPShellAdmin –UserName <domain\account or securitygroup>
