Learning PowerShell

I recently had to learn PowerShell, and as a hacker with experience in software development in many languages, I picked it up pretty quickly.

Here's some of my initial questions on PowerShell;

• How to match a string enclosed in quotes
• Testing for string in PowerShell

Other useful things to know:

• How to determine what version of PowerShell is installed?
• How can I find the source path of an executing script?
• PowerShell grammar

The basic file extension for PowerShell scripts is: .ps1. Writing PowerShell scripts is like writing a Windows batch file, you just start writing what you need. It's possible to access any .NET methods, classes from PowerShell, and extremely easy.

Here's the classical Hello World in PowerShell:

"Hello World"

That's right. There's no echo or println required. One can also do it like:

write-host("Hello World")
