We have Don Jones with us on the phone today.  Don Jones, for the three people who don’t know who he is, has authored over thirty books.  He’s a frequent speaker at conventions and also runs training classes for PowerShell.  Here are some notes we took during the conversation. 

• MS MVP Summit
• MMS last week
  • 5th year
• Training videos
  • fundamentals class, twice a week for 4 weeks = $400
  • scriptingoutpost.com
• New version of Primalscript 2007
  • coming soon: visual forms editor
• Blog: blog.sapien.com
• CTP2
  • e-book on sapienpress.com: PowerShell v2: TFM, updated for CTP2!
  • Remoting
    • push cmds to remote computer
    • bring results back
    • interactive like ssh
  • transactional registry operations
  • create your own cmdlets (script cmdlets)
  • new little features
    • convertTo-Html
      • head parameter
      • css links
    • get-wmiobject
    • get-process, get-service
  • send feedback to connect.microsoft.com
  • New graphical console
• Shows coming up: Tech Mentor, TechEd
• New e-books: 2008 Server - What’s New, What’s Changed, Exchange Management: TFM, cookbook style

Resources

• Tobias from ScriptInternals has just started a PowerShell blog, you can find it on PowerShellCommunity.org.  He intends to post often about how to use PowerShell Plus features.
• Real quick mention for newbies: you must see these tutorials.
  • Essential PowerShell by Kirk Munro (aka Poshoholic)
  • Keith Hill has his Effective PowerShell series which is also great.
  • Mastering PowerShell in your Lunch Break is another favorite.
• New PowerShell Training Videos from ScriptingOutpost.com from Don Jones
• Quest AD Cmdlets Beta 1.1 available

Tips

• We found a nice script on the blog post PowerShell and Excel (from the “Powershell,Passion,Persistence and Pursuit” blog).  This script reads a server list from a text file and collects IP configuration settings of each server and uses that data to populate an excel sheet.
• Using SQL with Powershell
  • PowerShell TFM
  • iSQL, sqlcmd, Invoke-Sqlcmd
  • Article: PowerShell, XML, and SQL Server
• Hal wrote an article that explains how to automate the syncing of iTunes to your iPod, using PowerShell of course.
• Interesting article that talks about working with Hyper-V virtual hard disks.  Some neat examples in there about passing text to console apps like diskpart.exe.

One-Liner

• $env:path.split(’;') updated by John Cook

Gotchas

• The alias for Set-Content collides with sc.exe.  Workaround is to be sure to type sc-dot-exe.
• There is no Remove-Alias cmdlet!  You can use the alias: PSProvider with “del” to get the job done.
• Oisin Graham has written about a big gotcha with working with remoting and WinRM with computers which are not domain members.

Give Away

• As mentioned at the top of the show, we’ll be announcing the winner of our Vista Ultimate giveaway next week.  If you want a chance at it, send us feedback about the show to powerscripting@gmail.com.

Emails!

• We got some GREAT feedback from a few listeners lately.  Some of whom were obviously motivated by the free copy of Vista, which is why we did it. 

This little one-liner will show the most common verbs among all the cmdlets installed in the current PowerShell session.

   1: PS > gcm -CommandType cmdlet | Group Verb | Sort Count -Descending | Select -First 10

   2: 

   3: Count Name                      Group

  14:    10 Move                      {Move-Cluster, Move-Datacenter, Move-Folder, Move…

I just realized the above is the CLI equivalent of looking at a screenshot of someone’s Windows desktop and wondering what all those tray icons do. 

What snapins do you think I have installed?  What about you guys?

• We want to highlight a ton of IMPORTANT posts which Jeffrey Snover has made over the past few weeks:
  • How Could You Top CTP1?
    • This post has the background for why and how some upcoming changes will be made.
  • Changes in upcoming CTP
    • This post has an extract from the release notes for CTP2. Very important to read if you want to keep up with the new version. There’s also some good discussion in the comments attached to the article.
  • Get-Random
    • I love this quote: I saw THIS posting over on Mark Minasi’s forums that caught my eye. It gives you a random help file under the motto of: “A powershell help file a day, keeps Don Jones away”
    • The article goes on to talk about a new cmdlet by the name Get-Random which will get you a random number, or–grab a random item from a collection.
• iTripoli just released version 3.5 of their Admin Script Editor. (Should be out by the time you read this.) It now includes a debugger and has a ton of PowerShell templates.
• VMware just announced that Beta 2 of VMware Server 2 (the free version of their virtualization software) is manageable by their PowerShell Toolkit! This is awesome news for smaller shops which have not shelled out for their higher-end Virtual Infrastructure products.

   2. The graphics in the GUI are embedded WITHIN the script file using base-64 encoding.

Thanks a bunch to Steven, we had fun with the interview.

Resources

• We have two links for you today from John Robbins, author and master debugger. It’s a heartwarming before and after powershell love story. He also links to a Compile-Help script which we somehow missed when it was new. This script grabs the help files from all installed cmdlets as well as the about topics, and packages them into a HTML help file for easy reading.
• Carter at VMware (yes, Hal has a thing about them, sorry) also blogged about a way to have your VMware alert events fire off instant messages using Jabber

One-Liner

• One liner sent to us by John Cook and a write up on his blog
  • $env:path -replace “;”, “`n”

Today we speak with Thomas Deml from Microsoft.  He is the Senior Program Manager in the IIS team.  He’s been with MSFT for 17 years!  Old timer. His team “owns” the core engine of IIS and the PS provider is a subset of that.  Below are some notes from the interview.

• Who are you
• What’s your background at MS and elsewhere
• Talk about the IIS7 management cmdlets
  • Get/Set-WebConfiguration
  • Start-WebItem
  • Remove-WebConfigurationProperty
  • Ability to use XPath filters
• Talk about the IIS7 PSprovider
  • Provider timeline - 2nd beta in June, final in October
  • Features
    • ability to configure IIS and ASP.net, sites, vdirs, apps, all that
    • ability to delegate
    • root of namespace: sites, app pools
• What does the future hold (that you can discuss)
  • We talk about Server Core

Tips

• This came up on #PowerShell (on freenode.net): How can I remove an item from a collection? 
  For example “$servers = get-QADComputer srv*”.
  • Option 1 - Set the item to $null.  This does not actually remove the item, but for most purposes it serves well.
    • $servers[3] = $null
  • Option 2 - Create a new collection which is a subset of the first.  Drawback here is double the memory as the collection is copied in place.
    • $servers = $servers -ne “itemthatyouwantremoved”
  • Option 3 - Use system.collection.arraylist instead of a generic array.  More steps, but the item or items are removed, and it much more efficient than option 2.  The Scripting Guys explain it well in one of their PowerShell tips of the week.
    • $servers = new-object system.collection.arraylist; $servers.Remove(”item”)
• PowerShell Power User Tips: Current Directory - The core of this tip is very simple: Windows tracks your application’s “current directory” … and you can get and set this location using static methods of the System.IO.Directory class: SetCurrentDirectory and GetCurrentDirectory.  (Thanks Jaykul of Huddledmasses.org.)
• Newsgroup posts
  • “Excel Row Format” - In this thread, Oisin explains how to teach yourself how to automate Excel by examining vbscript created by the macro recorder.
• This snippet is from Chris in Charleston, SC.  He sent a long email with feedback (which you all should do) with several suggestions.  Thanks, Chris!  This tip is that it’s quite easy to integrate the old with the new in PowerShell.  He’d also found that grep.exe in some cases is much faster than select-string, so it was a good example for his point.  Jonathan’s test had Grep for Windows 2:30 and Select-String 11:08 against the same 6.7 GB log file.
  • $cmd = “grep.exe `”$username`” $logfile”
    Invoke-Expression $cmd | Set-Content F:\4report\$username.txt
• Don Jones post “Include in PowerShell” dot source a PS1 file at the beginning of your script - http://blog.sapien.com/index.php/2008/04/08/include-in-powershell/

First, I go on vacation (this is Hal typing). Then, Jonathan has a big project at work which takes up our next available studio slot. Then, my weekend just totally filled up end to end. I’m afraid we still haven’t gotten Episode 23 out yet, folks! But fear not, this will not become a habit. We were really good about the two-week rotation, we’ll get back to it very soon.

In the meantime, let me tell you what we’re working on in upcoming episodes:

• An Active Directory special which will have not one but TWO MVPs (plus Jonathan who is a pro himself) around to answer your questions.
• A VMware special with a manager for part of their powershell efforts and possibly one of the devs on that team.
• IIS7 has a new PS Provider which will give you a filesystem-style interface to your site’s data and metadata (so I understand so far). We’re trying to line up the MS Program Manager for that tool, he’s volunteered so we just need to make the schedule work out.
• We’ve got the WinRM special. I think we’ll be able to get someone from the Server 2008 team to show up for that.

And there are a ton of other stuff out there. For example, I just realized we should have a Group Policy special, I know who to call upon for that. GPO Guy to the rescue! Oh, and MOM/SC, I know a local MVP for that who I’ll draft for the cause.

What would help us out more than anything from you guys reading is to leave feedback on the blog or send email in to powerscripting@gmail.com and let us know what strikes your fancy the most. Or if you have specific questions about the above technologies relating to how you can use them with PowerShell, send them on please.

We’ll get that next episode out RSN!

Hi all. Just wanted to let you know that I was out of town on vacation last week, so Jonathan and I were unable to record the show at our usual time. We’re getting together to record again this Thursday with an estimated air date of April 20th.

To make it up for you, we’ll try to do several blog posts this week with pointers to cool PowerShell stuff. I’ll start it off with this one from a very persistent sysadmin Ken who blogged his techniques for displaying some sweet PowerGadgets-powered gauges to monitor the CPU and memory utilization on VMware ESX servers. I say persistent because the solution did require a lot of work to get just right, and he goes into detail about those challenges so it makes a great tutorial for those new to PowerGadgets and the VMware VI Toolkit.

Tips

The Tips are brought to you today by ShellTools.

Did you know that PowerShell Plus is a great XML editor? In addition to .PS1 files, you can also work with .PS1XML help files and .PSC PowerShell Console files. Other new features include a really cool console preview pane in the editor which makes edit/test/correct workflow very easy. You can download it today at shelltools.com.

• Brandon Shell from the BSonPosh blog wrote a cool script which times the replication of objects in an Active Directory. Here are the features:
  • Finds all Domain Controllers in the Domain (using .NET)
  • Creates a contact object in a specified OU (Default is users container for the Domain)
  • Gets the start Time
  • Loops and Checks each DC for the object.
  • Once all DCs have the object it gets End Time
• Newsgroup posts:
  • Hal explains how to explore WMI in the command-line:
  • • “Win32_NetworkAdapter” -namespace “root\CIMV2″ -Filter AdapterTypeId=0
  • Shay elaborates on adding ScriptMethods to custom objects:
    • PowerShell Custom Objects
• Bart De Smet wrote a cool introduction to Script Cmdlets in PowerShell v2 CTP. It will be incredibly easy to write more robust scripts that have features such as mandatory parameters and “it just works” pipeline support. He also talks about -confirm and -whatif support. Very neat stuff.

In the olden days (i.e. when I used CMD.EXE), I often did “dir *.” to quickly get a list of the directories in the current path. PowerShell doesn’t work this way (which is good because it would be unexpected), so I had to make a replacement.

function Get-Directory { ls $Args | ? { $_.PSIsContainer } }

The alias which makes most sense to me for this function is “lsd”. What, that acronym is already in use?
