Microsoft PowerShell

PowerShell is Microsoft’s recommended Windows scripting language. Although the DOS based command language used in batch (.bat) files will continue to be supported PowerShell is the recommended replacement.

Logging Jobs with Start-Transcript — Powershell (.ps1) scripts supports much better logging than SQL Server Agent or Windows Task Scheduler (WTS). The Start-Transcript command captures script and program output at the script level. This level of logging catches error messages that other logging strategies miss. Logging features in application programs for instance don’t begin to capture error messages until sometime after the application program begins running. In contrast the job logging in SQL Server Agent and WTS is very minimal.
Run .bat File From PowerShell .ps1 Script

Default PowerShell Security

Some versions & installations of PowerShell have default security configurations which may prevent running PowerShell scripts. (There is more Windows security on PowerShell scripts than .bat files!)

There are ways to reconfigure PowerShell security that removes most restrictions. Ask your IT security people for the PowerShell security policy.
Documentation is a work-in-progress.
