Mike Fal casts out SQLPS and looks at new and updated Powershell cmdlets:
An important facet of the provider is that it behaves like a file system. How many of us have deleted files from the command line? Have you also used a PowerShell one-liner to delete old files, like backups? If you have, you might be familiar with two parameters: -WhatIf and -Confirm. These two switch parameters are extremely helpful because they can keep you from cutting yourself with that sharp PowerShell knife.
With the July 2016 update, the SQL Server provider now supports the use of these two switches. While using them may not be a common situation, it’s good to know that they are there. After all, it could be handy if you wanted to clean up some items from the command line, like maybe a junk database. Now you can both check what you’re going to do before you do it, along with getting a confirmation question when you go for the actual delete:
I am a huge fan of the -WhatIf switch, so that gets a thumbs up from me.
