PowerShell

beginner

Bash for Windows. Except it's also on Linux now. And it's object-oriented. Long story.

PowerShell is Microsoft's powerful shell and scripting language. Unlike Bash which works with text, PowerShell works with objects. This makes parsing command output dramatically easier. It's cross-platform and surprisingly capable.
