| Function Get-DateRange | |
| { [CmdletBinding()] | |
| Param ( | |
| [datetime]$Start = (Get-Date), | |
| [datetime]$End = (Get-Date) | |

| { $Start.AddDays($Num) | |
| } | |
| } |
To use it, simply call the function

- Get-DateRange -Start 7/24/14 -End 8/1/14
- Get-DateRange -End 7/20/14

Spicecorp Thursday, July 24th 2014
Should have posted this a couple of weeks ago, but I’ll be at the Boston Spicecorps this evening doing a quick, one hour introduction to PowerShell. It’s all about taking some of the fear away from using PowerShell. We’ll be going over objects and the 3 commands you have to know to really get into PowerShell:
- Get-Command
- Get-Help
- Get-Member
There’s about 10-15 minutes of slides to get through, then the rest of the time is all sitting in front of the ISE and writing a script from the inside out. If you’re not doing anything this evening and you are in the Boston area, swing by and say hello!

Exporting User Information
Need to export user information to a CSV? Perhaps as part of your termination user process? Incredibly easy with PowerShell, let’s see how to do it.
Extending the Active Directory Schema
Bit of a departure from my normal PowerShell-centric posts, I want to talk about extending the Active Directory schema. There’s some really great information on the Internet for doing this, but there are some things to consider and none of that information seems to be in one place, and I wanted to bring it together here.
