Automating the world one-liner at a time…
December 21, 2011Dec 21, 201112/21/11After delivering the Thanksgiving Gift this year, it’s time for a Holiday Gift …. No not as big as the one we had about 3 years ago …!!
Today, we published the “Getting Started with Windows PowerShell Workflow” document on the CTP2 download page,
May 26, 2009May 26, 200905/26/09There were quite a few name changes in the ISE Object Model from CTP3 to RC
Using Update-TypeData, we can achieve some parity between the two
We can add aliases to the CTP3 version to make it look like the RC Version
For example,
May 20, 2009May 20, 200905/20/09One of the nifty features of functions in PowerShell is that they can return as many results from as many places as you’d like. In fact, any method or cmdlet that would give you an output if you try it on the command line will also return values from a function.
April 22, 2009Apr 22, 200904/22/09One of the systems administration hurdles of the post-Vista world is figuring out how to make a script run as an administrator.
In PowerShell V2, using the Start-Process cmdlet, this is a one liner that will get the job done:
Start-Process "$psHome\powershell.exe"
April 21, 2009Apr 21, 200904/21/09Jeffry Snover and many other have used Start-Demo in powershell.exehttp://blogs.msdn.com/powershell/archive/2007/03/03/start-demo-help-doing-demos-using-powershell.aspx
Continuing the tradition, we now have ISEDemo.psm1
To use it, start ISE and runImport-Module ISEDemo.psm1 #(attached)Start-Demo c:\path\to\demofile.txt
Type enter to execute the command once its finished typing
You can escape to clear and type some other command
To get the next command again,
April 21, 2009Apr 21, 200904/21/09I just got a ping on our internal discussion list about how to get at the Performance counters in PowerShell. In V2, we’ve got some nifty cmdlets to help read performance counters.
Here are a few of quick one liners to get you started:
# List all of the performance counters you can monitor
Get-Counter –listSet * | Select-Object -ExpandProperty Paths
# Get one sample of the processor time
Get-Counter ‘\Processor(*)\% Processor Time’
# Get a sample of the processor time until you press CTRL + C
Get-Counter ‘\Processor(*)\% Processor Time’ -Continuous
Hope this Helps,

Limited support for interactive console apps, try cmd.exe, then try cmd.exe /k
cmd.exe /c dir still works though,
March 30, 2009Mar 30, 200903/30/09The other week, I showed a Get-ProgID function that I used to help someone at Microsoft Research find a good object to talk to images. A few comments jumped to one of the possible solutions, which is to use the .NET Drawing assembly (which I have to load first).
March 27, 2009Mar 27, 200903/27/09Have you ever created scriptblocks on the fly, say in a foreach loop, and they totally mess up because they all have the same value?
This is something sort of advanced, and typically used when you’re proxying an object.
The most basic example would be,
March 26, 2009Mar 26, 200903/26/09With Add-Type and $executioncontext you can add special varibles that have tied values.
I made $random, and $now
add-type @”using System;using System.Management.Automation;public class RandomVariable : PSVariable{Random r;public RandomVariable () : base(“Random”, 0, ScopedItemOptions.ReadOnly | ScopedItemOptions.AllScope) {r = new Random();}
public override object Value
