INTRO TO POWERSHELL

AGENDA• What is it

• Why you should care about it

• What products can benefit from it

• System requirements

• Resources

WHAT IS POWERSHELL?• .NET Scripting Language from Microsoft used for task automation

and configuration management

SIMPLE POWERSHELL EXAMPLE

OBJECT-ORIENTED NATURE OF POWERSHELL

WHY YOU SHOULD CARE ABOUT POWERSHELL• Managing one user in a GUI = easy; managing hundreds of users in a GUI = time-consuming

• Many click-click-click processes can be automated

• Automating processes with a script makes processing quicker, giving you more time to tackle other issues or projects

• VBScript is a thing of the past; a lot more products are using PowerShell for administration

WHAT CAN IT AUTOMATE?• List all computers on a network, with their operating system and service pack level

• Start a service on multiple computers

• Manage Active Directory users

• Scrape all the event logs on your network for a particular error

• IIS website setup

• And many more!
