If you’re just learning PowerShell or you’re already a top scriptwizard “Mastering Powershell” might prove to be a useful resource.
Besides the usual scripting basics like variables, functions, pipes and so on the later chapters show some usage of the scripting language for some more concrete problems like XML manipulation or user account management. Just give it a try, it’s free!
tu mi-ai aratat powershell-ul si tot tu imi dai si cartea! Multumesc!
