I am a long time user of SSMS/TSQL, but, am looking to get into PowerShell for SQL Server. I know that I can start an instance of the PowerShell SQL minishell by right clicking a database in SSMS and clicking Start PowerShell. To try and set up some automated tasks (read that to mean scheduled tasks) I want to see if the same shell can be accessed via a script, and, if so, how. My first concern is how to pass credentials. I have located where the sqlps.exe is and I need to be sure and log on with an account that is in SQL. I presume the credentials are automatically passed from SQL Server via token to the minishell when you start from the context menu. In my case, I have to figure out how to ensure the same credentials are passed via script. Any links or code samples would be helpful. From a PowerShell perspective, I am a total SQL Server beginner.

So... you know the minishell is gone in SQL2012, right? And it isn't special except that it won't let you add other snap-ins. You can open a normal PowerShell console and add the SQL snap ins, and get the same functionality the minishell allows.

Ah, that's news to me. Thanks for bringing me up to speed. At this point, we are still on 2008, but, I suspect we will migrate relatively soon. Any idea why the decided to go with the SnapIn for 2012 as opposed to modules? I thought most everything was shifting to module-based extensions.
For anyone else curious about this, I get the following on my machine (PowerShell v3/SQL Server 2012) when I check:
Name : SqlServerCmdletSnapin100
PSVersion : 2.0
Description : This is a PowerShell snap-in that includes various SQL Server cmdlets.
Name : SqlServerProviderSnapin100
PSVersion : 2.0
Description : SQL Server Provider
Once I do this I can start working with cmdlets:
Add-PSSnapin -Name SqlServerCmdletSnapin100
Guess I'll be playing around with my laptop this weekend!

So, in 2008 you've got a Snap-In, which can be loaded into any PowerShell session; the SQL minishell simply preloads it and then prohibits loading any others.
In 2012, you've got a module (two, I think), and a mainly provider-based model. So you get a SQLSERVER drive. But it's based as a module, and there's no minishell to preload it and exclude the loading of others (the minishell concept was well-intended but ultimately a bad idea).
So 2012 did repack the functionality into a module.

Got it. Thanks for filling in the blanks Don.

One other point on SQL 2012. The sqlps host (sqlps.exe) provided which is in addition to the sqlps module no longer implements a shellid and so allow snappins and modules to be added. To use SQL authentication instead of Windows authentication as you requested you would need to use new-psdrive with cred parameter as described here:
