Q&A

What’s this all about?

What can you say about any good systems administrator? They’re lazy... Why would we say this?

A lot of our daily tasks are repetitive, mundane, and required!!! So how does that make a good systems administrator lazy? Using automation, scripting, and doing more with less is lazy! (Insert something about the economy ‘here’)

Powershell does this! Powershell loves this! And it’s easy!

PowerShell?

What is Powershell?

Wikipedia calls it : Windows PowerShell is an extensible command-line shell and associated scripting language from Microsoft. It was released in 2006 ...

We call it : PowerShell is geared around making your life as an ADMIN Easier. PowerShell can be used for:

Scripting! - Automation, Woot!

Interactive Command Shell

GUI!

MSDN calls it : Windows PowerShell is a new Windows command-line shell designed especially for system administrators...
