Just go with the flow…. WorkFlow that is with Windows PowerShell
Doctor Scripto returns again with our good friend Joel Vickery, PFE who is going to touch on the use of Workflows In PowerShell. Take it away Joel! Following up on my original post Parallel Processing with jobs in PowerShell, I wanted to go into another method of running parallel processes in PowerShell, namely WorkFlows. WorkFlow is very similar to using the Start-Job/-asJob functionality but it has some distinct advantages that are fully covered in many other blog postings on TechNet. I'll mention them quickly below, but if you want deeper detail, see the When Windows PowerShell Met WorkFlow blog posting...
PowerTip: Identify Completed PowerShell Jobs with Data yet to be Received
Summary: Doctor Scripto quickly shows how to identify Completed Jobs in PowerShell which have yet to have the data Received Hey Doctor Scripto, How can I identify jobs which already completed but I haven’t done a Receive-Job on to get the data?

Use PowerShell to Identify Unassociated Azure Resources
Summary: Save costs by Identifying Unassociated Resources left behind after deletions in Azure Q: Hey, Scripting Guy! How can I quickly identify un-associated resources in my Azure subscription? A: Hi SH! At least you know that’s a question to ask! I myself when I first began exploring this new world didn’t realize that when deleting a virtual system in Azure, not all the associated resources are deleted with it! First things first, if you’ve never done it, you’ll need to install the Azure PowerShell modules. This can be done by following the steps provided here on docs.microsoft.com Install the...

Using PowerShell to View and Remove Wireless Profiles in Windows 10 – Part 4
Summary: Using Windows PowerShell to purge Wlan profiles with NetSh.exe. Last week we had a way with a Regular Expression to run one Netsh.exe command and show only the profile names as a PowerShell Array. Today we're going to finish the task and show you how to delete those Profiles. As a quick reminder here's the line in PowerShell we used to capture the list of Wireless profiles by only their names as an Array. The resulting output containing our Wireless profile names looked like this From our first posting we saw that to delete a WLAN profile in Netsh.exe we would execute this command. ...
PowerTip: Show all Installed Capabilities on Windows 10
Summary: Identify if capabilities like OpenSSH are installed in your Windows 10 Operating System Hey, Doctor Scripto.

Using PowerShell to View and Remove Wireless Profiles in Windows 10 – Part 3
Summary: Using Regular Expressions to cleanup string data from NetSh.exe. Let's remember the last two discussions. The first time we looked at using PowerShell to identify wireless profiles with some simple regular expressions. We followed up the next week with how to identify which approach would be the fastest. Today we're going to take that array of information and clean it up so we only have the profile names. As a quick reminder here's the line in PowerShell we used to capture the list of Wireless profiles The resulting output looked like this What we need to do now is cleanup this data so...
PowerTip: Identify Drives Encrypted with Bitlocker
Summary: Using the Get-Bitlocker Cmdlet to show the status of drives on your Windows 10 computer Hey, Doctor Scripto. Is there a nice simple way to see if drives are Bitlocker encrypted?

Get-BitLockerVolume | Where-Object { $_.VolumeStatus -eq 'FullyEncrypted' } PowerShell, Doctor Scripto, PowerTip, Sean Kearney
Using PowerShell to View and Remove Wireless Profiles in Windows 10 – Part 2
Summary: Using Measure-Command to determine the fastest approach to a solution. Last week we were having some fun using PowerShell as a wrapper around the NetSh.exe command's output. We were left at a decision point. Which way to go? A For loop to clean up the data, which worked fine or Regular Expressions. Although both work which was the better path to use? For me initially, when I first started in PowerShell I very often used a For loop for a few reasons. But as I progressed in my knowledge of PowerShell I've started to touch on Regular expressions as a solution when possible. A go...
PowerTip: Converting a Here-String to an Array in One Line with PowerShell
Summary: Using the split method in a more powerful fashion to split an array based upon two line terminating types Hey, Doctor Scripto. I was wondering if there was a more efficient way of converting a Here-String to an Array when there were multiple line termination options like Linefeed or Carriage Return and Linefeed? There most definitely is. You can pass multiple parameters to the split method. This example traps both! $HereStringSample=@' Banana Raspberry '@ $HereStringSample.Split(@("$([char][byte]10)", "$([char][byte]10)","$([char][byte]13)", [StringSplitOptions]::None)) PowerShe...
Using PowerShell to View and Remove Wireless Profiles in Windows 10 – Part 1
Summary: Using PowerShell and Regular Expressions as a wrapper on NetSh.exe output to identify the profiles. Hey, Doctor Scripto! I have a whole pile of old Wireless profiles that have been collecting dust. I know I can use NETSH to view and delete them, but the process is very manual. Do you know if there is an easier way to clear them up? —WF Hello WF, you asked I shall help. Doctor Scripto is in the house! I know the process you mean, I had to do this a few years ago on one of my old laptops. I had wireless profiles from my home, hotels, offices, coffee shops. It was just silly. I think there we...
PowerTip: Identify which Platform PowerShell is running on
Summary: Using $PSVersionTable to identify if you are on Windows or Unix Hey, Doctor Scripto! I'm working on my PowerShell scripts and I need to be able to identify if I'm working on Windows or Linux. How can I do this easily? No problem at all and glad to help.

Maximizing the Power of Here-String in PowerShell for Configuration Data
Summary: Discovering some of the awesome and neat ways to leverage a Here-String in a Script or function Q: Hey, Doctor Scripto! I used to write scripts with supporting configuration files that never really changed. I was wondering if there was any way to put them INSIDE the script directly to make it self contained. —AB A: Hello AB, I was chatting with my good friend Sean on this one. Here he talks about using Here-Strings to solve this problem. Thanks Doctor Scripto, yes a Here-String can be a great way to embed the configuration or other data for that matter in a script. If you've never encou...
PowerTip: Read a JSON configuration file as a PowerShell object
Summary: Using the ConvertFrom-Json Cmdlet in PowerShell to read a JSON formatted file Hey, Doctor Scripto! I've seen a lot of JSON files in use in Azure. I'm not very good with editing JSON properly. Is there an easy way to read this and at least edit it with PowerShell? Most definitely my good friend. For the file below called "settings.json" you can convert it to a PowerShell Object for editing purposes using the following line. Once you have completed this, you can manipulate it like any other PowerShell Object. $PowerShellObject=Get-Content -Path settings.json | ConvertFrom-Json Pow...
Configuring Startup Settings in Microsoft Teams with Windows PowerShell
Summary: Using the ConvertFrom-JSON and ConvertTo-JSON Cmdlets to edit a configuration file Q: Hey, Doctor Scripto! I need to be able to change the Startup settings in Teams (like the Auto launch feature). I can change it in the Interface, but I need to be able to edit across multiple systems. Could you lend me a hand? —RL A: Hello RL, A very excellent question. For which it produced a most interesting solution when I asked Sean Kearney one of our Microsoft PFE's to look at it. Take it away Sean! Let's begin by examining the settings we are trying to change. They can be accessed under the "Setti...
PowerTip: Using PowerShell to Convert raw Text to a Comma Separated columm
Summary: Using PowerShell and a very simple Regular Expression to convert Random counts of spaces to a Comma Hey Doctor Scripto! I have some string based output from a non PowerShell application. The output is good but I need to easily parse it. Is there a way to convert that data to something consistent like "Comma Separated?" Why yes you can! This is something that is easily done with a regular expression. Using a simple example like this will identify all content with more than one blank space separating it, and replace it with a comma! $SampleText='Hello This ...
Automating Quser through PowerShell
Summary: Using PowerShell to automate Quser to identify users to Logoff systems in Windows Hey Doctor Scripto! I need to log a user off every computer they’re logged into. The problem is, I don’t know which ones. How can I discover which computers they’re logged into and then log them off? That's a most excellent question! I know just the person who can answer that. I was talking my good friend Dan Reist on this topic. Dan is a Senior Consultant on Data Platforms here at Microsoft. He actually ran into that same issue. Dan, the room is yours today, take it away!

PowerTip: Show files with expired Digital Certificates
Summary: Targeting Expired Certificates with Get-AuthenticodeSignature Question: Hey Doctor Scripto! Is there an easy way to visually identify Digitally signed files with an Expired status on the Digital Certificate? Answer: Absolutely! We just need to filter on the “Status” property and show those without the value ‘Valid’. As an added bonus it would also identify files that are not digitally signed. Get-Childitem C:\Folder\*.* -Recurse | Get-AuthenticodeSignature | Where-Object { $_.Status -ne 'Valid' } PowerShell, Doctor Scripto, PowerTip
Reporting on Digitally Signed Files with PowerShell
Summary: Using the Get-AuthenticodeSignature cmdlet to show if a file is Digitally Signed Q: Hey, Doctor Scripto! I was curious, since many new files are Digitally signed with a certificate if there was an easy way to see the status of the Digital Signatures of many files easily? —SH A: Hello SH your good friend Doctor Scripto is here today to help you along. One of the things which changed with PowerShell in version 3.0 was a beautiful little Cmdlet called Get-AuthenticodeSignature This Cmdlets task was very simple, examine a file and show the properties of the Digital Certificate on a file.

PowerShell PowerTip: Customizing your prompt
I've been taking a break from the blog for a while due to some personal reasons, but I had a few people ask me about my PowerShell prompt recently. I like extra horizontal space, so I removed the path from the prompt and put it in the window title bar. I also just display the current time in the prompt itself. You can customize your prompt by using your profile and overriding the "Prompt" function. A coworker of mine, Tony Radkiewicz, used a similar prompt and I really liked it so I've been using it since. That's all for now, I'll try to get some...

PowerShell PowerTip: searching and installing modules on the command line
PowerShell 5+ ships with the module PowerShellGet, which lets us search and install modules from cmdlets. The default nuget repository is the PowerShell Gallery, but you could add others yourself (including custom ones for internal modules). There are a lot of reasons this could help you: There are a lot of cmdlets in the module, but the ones you'll use the most will be: You can also specify the scope on install-module and put it in your user module location for ones just for you on a machine. Hope that helps, tune in more often to get short and sweet PowerTips!
Regular Expressions (REGEX): Grouping & [RegEx]
Welcome back to the RegEx crash course. Last time we talked about the basic symbols we plan to use as our foundation. This week, we will be learning a new way to leverage our patterns for data extraction and how to rip our extracted data into pieces we care about. [RegEx] The data type has some cool static members, but we're mostly going to play with the plural method if you don't know what static members are you can check this post or this help data. A lot of the time, when we work with RegEx we are using it to extract everything that matches our pattern in a large amount of data. Using like we did in t...
PowerShell PowerTip: History of commands with PSReadline
One of the really cool things PSReadline provides (module shipping on v5+) isn't as immediately obvious as the syntax highlighting. It offers a persistent history that is stored from session to session. This means if you run commands in a window, close it, and open a new one later you can still hit the up arrow and scroll through them. I use this feature quite a bit doing demos or just working on things where I want to clear out my whole scope and jump back in. If you want to opt out you can as well: Hope that helps, tune in more often to get short and sweet PowerTips!
Regular Expressions (REGEX): Basic symbols
Welcome back to the RegEx guide. Last post we talked a little bit about the basics of RegEx and its uses. I mentioned the most important thing is to understand the symbols. Today we'll ease in with some of the basics to get us going, but later we will expand on these and see some other options we have. is used to represent any single character, aside from a newline, so it will feel very similar to the windows wildcard is the escape character for RegEx, the escape character has two jobs: We can use to specify quantity in a few different ways by attaching them to characters or symbols. ...
PowerShell PowerTip: What is the point of Out-Variable?
A lot of times people see others using the common parameter -OutVariable instead of the best practice $var = <value>. This leads to a lot of folks wondering why OutVariable exists. The real use for OutVariable is to save your data off, while still letting it get sent along the output stream. What this means is that you could use it somewhere inside of a pipe to save some data for later re-use, but continue doing other work with that data. Notice that even though the data continued being pipped along, I could also reference it later when I asked for the count. Hope that helps, tune in more ...
PowerTip: Turn off the power to your computer with PowerShell

PowerShell PowerTip: What you should know about streams
PowerShell has a concept called Streams, which are the different places data can go (output, error, verbose, etc). You usually don't have to worry too much about these streams if you're just writing simple scripts, but it helps a ton to know: What this means for you, as users, is that you can get a non-terminating error, and still do work on the successful output. Take a look at this: Notice that even though I received an error for the process "FAKE", only the non-errors were present in $procs. Using some basic error handling we could clean that up, hide the error message and log out wha...
Regular Expressions (REGEX): Introduction
Hi all, this week I'll be talking about Regular Expressions. I've got a few posts planned to get you set up and going with some basic Regex. Regex is used for extracting and validating data. Essentially, you can think of Regex as windows wild cards on steroids. Anytime we need to match data with a little more clarity than the *s and ?s that windows gives us, we have Regex. Regex has a reputation for being difficult and confusing, but it really isn't so bad when you get used to it. The biggest contributors to Regex's reputation are: With that in mind, let's take a look at a sample about why you ...

PowerShell PowerTip: Checking your PowerShell version
If there is one question I could say I get the most in PowerShell, it is: How do I check my version? Its not a hard thing, but its not an obvious thing. We can actually check our version with a build in variable called PSVersionTable Hope that helps, tune in more often to get short and sweet PowerTips!
PowerShell For Programmers: Here Strings, There Strings, Everywhere Some String Strings
There won't be much code in today's post, but this can be a useful feature to know about. In addition to the expandable and literal strings we talked about, we can also use something called a Here String. Here strings allow us to have quote characters inside of our string that match the quote characters we use to create that string. For example, you might want the double quote character to appear inside of your expandable-string. You could use the escape character on the internal quote to prevent it from closing your string, but if you had a massive amount of quotes this would be annoying. Here strings exis...

PowerShell PowerTip: Grabbing the location your script lives in
One super common thing in PowerShell is to design a script to consume particular files for data. Often times you are building the script right in the folder for your files. However, it can be annoying to give long, literal file paths to a file. Also, if you give that script to someone else, they need to edit that path to point at the right location-- how annoying! There is a built in variable to help with this scenario: $PSScriptRoot will provide the file path the script was run from, which can let you relatively point at files. You can see an example of this in an older blog post. I received a few questions ab...
Working with JSON data in PowerShell
Welcome back everyone! This week we will take another look at some common data types we might encounter in the real world: JSON data. JSON data is used pretty frequently on the web if you're hitting APIs. This not only includes external data (twitter, weather, marvel database), but often includes internal data to your company. It's nice to be able to leverage data from anywhere, and it can be frustrating for people to try to parse JSON data. Luckily, we have this all built in for you using ConvertFrom-JSON I'll get a response from an API online used for testing: The response data looks like this: A...

Run PowerShell code in Puppet
Normally, it’s preferable to use specific Puppet and DSC Windows modules to manage systems in Puppet, but an alternative is running PowerShell commands and scripts by using the <strong>exec</strong> resource. This can be helpful for transitioning existing PowerShell code into Puppet quickly.
Doing more with functions: Verbose logging, Risk mitigation, and Parameter Sets
Welcome back to PowerShell for Programmers, this week I'm trying gitGist again for the code blocks. Let me know what you think about it vs the normal syntax highlighter I use :) As we've seen in the other posts about functions, attributes are a really cool thing to extend the features we have available to ourselves and for our users. This post is going to deal with an attribute for the function itself as well as ones for the individual parameters. This will let us make our functions behave more like any other cmdlet, by giving us access to the common parameters that users are used to seeing. Common Parameters...

Let’s explore how to use PowerShell to export local certificate information to a comma-separated values (CSV) file on Windows 7 (or later) computers. Q: Hey, Scripting Guy! How can I get all my certificate info into a CSV on my Windows computers? —SH A: Hello SH, Patrick Mercier here, with my first “Hey, Scripting Guy!” post. This question has come up at multiple customer sites, as they plan a new PKI infrastructure or a revamp of their current one! There’s tons of resources on using PowerShell for querying certificates, but questions around finding exp...
Grabbing Excel (XLSX) values with PowerShell
The Goal: Import data from XLSX files conveniently like import-csv lets you do with simpler data. The preamble: Excel is a mainstay of the business world at this point, which means a lot of the data you might have to work with will come at you as an XLSX file or need to be one. This can be a bit annoying when scripting. If we're just working in PowerShell-land and we can choose to use simple CSV data we have the handy import-csv and export-csv cmdlets, and those CSV files can open up in excel just fine. However, when we are forced to work with XLSX files it can lead to headaches. If you search around ...
Doing More With Functions: Comment-Based Help
I just wanted to throw together a post highlighting how cool and easy it is to add help data to your own Functions and scripts. The help data gets added via comments. For functions the help data can go in three places: For scripts we just put it at the top of your script before you type the param() statement, or at the bottom, but the bottom will mess with code signing. Syntax just involves using a dot before the help keyword and then typing the help you want for it on the next line: Here is a list of all the keywords I found and short descriptions of them: For the most part, I recomm...
Inserting new elements into XML files
The Goal: Insert nodes into a specific place in XML config files The Motivation: I had a coworker a while back working with App Fabric. He needed to insert a particular chunk of XML into a specific spot inside of the config file. This had to be done on a bunch of different machines, but the kicker was that the config files might look different on all of them. We knew the node that needed to come before our new node, but that might be in a different spot in each file. When the configSections node ended ( </configSections> ) we needed to insert: This is the perfect place for PowerShell auto...
Introducing the DscLcm utility for PowerShell
Summary: Desired State Configuration is a great deployment tool to meet your organization’s infrastructure-as-code goals. I recently came across a situation for a project that uses the Push Service (as opposed to the Pull Service). It required me to be able to apply a new partial configuration to a node, without any knowledge of what partial configurations were already in place. This led to the development of the DscLcm module, which solved that problem for my team. DscLcm module The DscLcm PowerShell module is a utility that interacts with the Local Configuration Manager (LCM) of a target machine. You don’t have...
Doing More With Functions: Taking Parameters on the Pipe
In an earlier post, I showed you how you could use the [parameter(mandatory)] attribute to force your parameters to behave a bit more like you'd expect from other languages. We also have a bunch of other useful attributes we can use on our parameters to enable cool features. Pipelineing The pipe might feel pretty magical to you in PowerShell, as it just seems to work with our built in cmdlets. You can add this same kind of functionality to your own tools, and we give you two options to do so. First of all, here is what happens if you don't use this attribute: Pipeline By Value When we talk about stuff...
PowerTip: Build simple HTML with PowerShell

For example: $SampleDoc=@' This is a simple text Document in PowerShell That I am going to make into a Tiny web page :) '@ ConvertTo-Html -InputObject $SampleDoc ...
Windows PowerShell and the Text-to-Speech REST API (Part 2)
Summary: You can use Windows PowerShell to authenticate to the Text-to-Speech REST API. Q: Hey, Scripting Guy! I was reading up on the REST API for the Text-to-Speech component of Cognitive Services. I'm just starting to learn how to use REST and PowerShell. Could you spend a little bit of time and show me how to authenticate to the service? —SH A: Hello SH, Authentication is one of the biggest pieces you'll want to learn. Telling a system at the back end who you are, and knowing how to communicate with it, is very critical before you can do anything fun! Talking to the Text-to-Speech API is pretty easy onc...
PowerShell for Programmers: The Magic Switch!
Welcome back everyone, I'm trying out GitHub Gist for my code blocks this week. It lets you click and download them, as well as making them easy to edit. The downside is that I can't use my usual dark themed syntax highlighting. Let me know in the comments if you like gist or the old method better :) Switch statements in PowerShell are very cool, and by knowing some of the tricks it has in place it can save you a lot of time. Basic Syntax Let's start by taking a look at a basic switch statement. In C# you might write something like this: In PowerShell you could do this: Notice we don't use t...
PowerShell For Programmers: Strings, Quotes and Quirks
Welcome back everyone! This will be a short, but important entry for the guide. The difference between quote characters is something I’m asked about all the time. It is important to understand in PowerShell, but most of the time it probably won’t make a difference. TLDR: If you're just typing a value like "alg" then it doesn't matter, but if you have any special symbols you can see the difference. Single vs. Double Quotes We refer to single quotes as Literal Strings and double quotes as Expandable Strings. Both create the same datatype (system.string), but a double quote will expand any special charact...
PowerTip: Create new authentication keys for AzureRM Cognitive Services
Summary: Change the keys to authenticate to Azure RM Cognitive Services, by using Windows PowerShell. Hey, Scripting Guy! I created the keys for my Rest API. I know I can change them in the web portal, but is there a faster way of doing it through Windows PowerShell? There absolutely is! Just use the New-AzureRMCognitiveServicesAccountKey cmdlet to reset either Key1 or Key2 (or both). Here is an example, where we generate a new sequence for Key1: New-AzureRMCognitiveServicesAccountKey -ResourceGroup 'HSG' -Name 'Sample' -KeyName Key1
Windows PowerShell and the Azure Text-to-Speech Rest API (Part 1)
Summary: You can use Windows PowerShell to authenticate to the Microsoft Cognitive Services Text-to-Speech component through the Rest API. Q: Hey, Scripting Guy! I heard about the cool Microsoft Cognitive Services, and had heard they have a REST API. Does that mean I can use PowerShell to consume them? Could you show me how to authenticate to it? —SH A: Hello SH, I just love waking up and saying "YES YOU CAN!" when people ask "Can you do that with Windows PowerShell?" So… ahem…. "Yes you can!" For those who didn't know, Cognitive Services are hosted in the Azure cloud, and they allow you to many things eas...
PowerTip: Use PowerShell to read an RSS feed
Summary: “Hey, Scripting Guy!” shows you how to use Invoke-RestMethod to read a list of entries from an RSS feed. How can I use Windows PowerShell to see the list of articles from an RSS feed? Just use the Invoke-RestMethod and provide the full path to the link to the RSS feed. Here is an example: Invoke-RestMethod -Uri 'https://blogs.technet.microsoft.com/heyscriptingguy/rss.aspx
PowerShell and the REST API for the IT pro
Summary: This post provides a quick introduction to what the REST API is, and how it applies to Windows PowerShell. Q: Hey, Scripting Guy! I can see there is this cool cmdlet called Invoke-RestMethod. I've been told REST API's are all around, and this allows me to consume that data. Could you give me a hand getting started? —SH A: Hello SH, Glad to help out! I remember hearing about REST APIs the first time, thinking they might be a way to take a nap at work. Was I wrong on that one! What a "REST API" is at the most BASIC level is really just a very fancy web Endpoint. You could, if you were really creative, t...
PowerShell for Programmers: How to write a function the right way
Just like I mentioned in my first post, PowerShell supports a lot of stuff that makes it pretty easy to dive in and get stuff running. The following two examples are supported in PowerShell, but not something you should really be doing for any reusable tool set. Putting your parameters (arguments) next to the function name in parenthesis is pretty standard in most languages, but in PowerShell it will limit your functionality. Similarly, $args will stop working for you if you add some of those more useful features, but I’ll show you a way to mimic the functionality on your own later. So, how should you b...
PowerShell for Programmers: What happened to my operators?
Operators are one of the most frustrating things about learning PowerShell if you’re coming from just about any other language in existence. Operators like ==, <=, !=. etc. are almost ubiquitous in programming, but none of them are supported in PowerShell. This can lead to some pretty frustrating errors with things like If statements. You might see: In PowerShell we are still going to have all these operators, they are just going to look different, using dashes and vaguely resembling parameters. I wondered the reason behind this myself for a while, and made a pretty inaccurate guess, but...
PowerShell for Programmers: Basic Syntax – Variables, Objects, and Data Types
Variables Variables in PowerShell are going to be a bit different than they are for you in most languages. To start out the conversation, the basic way to create a variable is just by using a “$” and an “=”, but there are cmdlets and other ways to generate them. Objects Objects are going to work how they do most places. Dot notation lets us dig into their properties and methods. If you want to see your object’s members, we have several options: 1. Get-Member: you’ll notice the definitions look a lot like you’re used to in C-based lang...
PowerShell for Programmers: A Quick Start Guide
Now that my content has been migrated to the scripting blog, this will be the landing page for the series and I'll be trying to update all the links. Learning PowerShell can be very useful for people with programming experience. Whether you’re currently a developer, dev-ops, or an admin you can get some serious use out of being familiar with PowerShell. You might think its just a version of command prompt with an eye-burning color scheme, but it really is a full scripting language with lots of nice tie ins. PowerShell is geared towards IT admins and made easy to learn with lots of nice shortcuts, and auto-...
PowerShell For Programmers: Basic Syntax — CMDLETs
PowerShell might look really strange to you. Many people assume PowerShell is basically CMD-prompt 2.0 because of the way it looks, but it really is a fully operational scripting language underneath. PowerShell has something called a cmdlet (command-let), which for the most part is the same idea as functions you're used to from other languages. I'll assume you're coming from a more classic language and you're used to calling functions like this: If you've been using cmdlets in PowerShell like this, you've been doing it wrong. This could cause you some serious problems down the line. "But I can type ...

Script Wars: The Farce Awakens (part III)
Summary: When last we saw our hero, Rey Skyworker, she was aiding her new co-worker, Tin. They managed to implement better error trapping by using the "Try Catch" statement in Windows PowerShell. The fact they could do this so easily it has tickled Tin's curiosity. ---------------------------- "Now Rey, I'm looking at this and as I see it, I could avoid the error altogether by trapping for those situations. Maybe adding in a few IF statements like this to the script." If (($First -or $Last)) -eq '') then { Write-Output 'Names cannot be blank } Else { ….rest of the script } Rey nodded. "You mean adding ...

The company: Contoso Holly Jolly Hat Company. She is being introduced to her new co-worker on the help desk, Jeremy Tinnison. ---------------...
Script Wars: The Farce Awakens (part I)
Summary: Seven years ago, “Hey, Scripting Guy!” was approached by a member of the community to see if we would be interested in doing something a little fun for the holidays. The result was a seven-part series called “A PowerShell Carol.” So when we were approached continuously in following years, we allowed this madness to continue! The tradition continued on with the "Blues" in Blueville and Curly Blue, amongst others, doing a twist on popular holiday stories. The community even dared to touch upon classic tales, with "Oliver Script," a "twist" on another famous story by Mr. Dickens. And now, we bring you th...
PowerShell support for certificate credentials
Summary: It's not a very well-known feature, but the PSCredential object, and the PowerShell Get-Credential cmdlet, both support certificate credentials (including PIN-protected certificates). In this post, we take a look at how a certificate credential is marshaled inside a PSCredential object, how you can do this marshaling yourself, and how you can retrieve the original certificate from a PSCredential object supplied to you. Most Win32 APIs that support the PSCredential object for credential validation already support certificates. However, if your code currently consumes a PSCredential, and you use the user ...

A brief look around the Internet came up empty, so I thought I'd share the challenge and the solution to this puzzle with you. The challenge If we take a lo...
PowerTip: Get a GUI interface for any PowerShell cmdlet
Summary: Use the Show-Command to build PowerShell cmdlets. I ran into a problem. Some cmdlets have too many parameters to list. Is there an easy way to build a cmdlet with its parameters for the console? You’ll love this trick! Just use the Show-Command cmdlet with any PowerShell cmdlet to get a GUI interface. In the following example, we use this with the Import-MDTDriver cmdlet. When you are done, you will have three options: Run, Copy (for the clipboard), or Cancel.
Find ready-to-use sample PowerShell scripts in the GUI
Summary: Honorary Scripting Guy, Sean Kearney, goes over some often missed, easy-to-use PowerShell techniques for those who are starting out. I had heard a rumor that many of the management tools actually run PowerShell code in the backend. Is there any way to see what code it’s running? Honorary Scripting Guy, Sean Kearney, is here today, and, yes, it’s true. This hidden gem is one of the most frequently missed pieces by many people who use PowerShell. The GUI in many cases is calling up PowerShell. Let’s begin with something pretty simple: managing users in Active Directory and auditing groups. For me, tha...
PowerTip: List all available CIM classes by using PowerShell
Summary: Use the Get-CimClass cmdlet to see all classes that you can query from. How can I find a list of Common Information Model (CIM) classes in Windows so that I can ask my computer useful questions? Just run the Get-CIMClass cmdlet to get a list of all available classes in the default namespace in Windows. If you’d like to filter on the list, you can use a wildcard.

A handful of people come in and for whatever reason have lock...
PowerTip: List all subfolders under a target path with PowerShell
Summary: Use Get-Childitem to provide a printable list of all folders under a path. I used to use tree.com to get a list of folders on a computer. Is there something close to that in PowerShell? Maybe something I could print? If you were to use Get-Childitem combined with Select-Object, you could get a pretty clean list. Here’s an example that targets drive c: and all hidden folders. It displays only directories and their full paths.

I once had absolutely zero time to learn about scripting or automation. I was a field technician. You know the typical work for some field techs. You get in the car, go to the call, hop back in the car, off to the next call, lunch in a drive-thru, sleep in a parking lot....
PowerTip: Use a destructive PowerShell cmdlet safely
Summary: Use the –whatif parameter with PowerShell cmdlets to test code live. I heard that PowerShell has a built-in safety switch to many of its cmdlets. Could you show me an example of it in use? No problem. You’re referring to the –whatif parameter, which is meant to show you what would happen if you used a PowerShell cmdlet without actually executing the cmdlet. An example of this in action is in the following Remove-Item cmdlet. This will attempt to remove the document, HSG-Article-Sean-Should-Not-Lose.docx, without actually removing it.
Use Windows PowerShell to search for files
Summary: Use Get-Childitem to search the files system with PowerShell. I saved a file somewhere on my computer and can’t find it. Is there a way to use Windows PowerShell to find it? Honorary Scripting Guy, Sean Kearney, is here today to show you a cool trick I use all the time. I use PowerShell to search for things constantly! Why PowerShell? Well, to be honest, I have a bad, bad, bad habit of putting data where it shouldn’t be. Sometimes I’d use locations that the Indexer in Windows isn’t watching. In these situations, even Cortana can’t help me. We can use Get-Childitem to show a list of files and/or dir...
PowerTip: Remove trailing space from a string by using PowerShell
Summary: Use the trim() method to remove leading and trailing spaces from a string. Could you do me a huge favor and show me how to get rid of spaces before and after a string in PowerShell?

Most of our rows kept dropping to the immediate left of the screen as in the following image: For this, we will look at one of our Here-Strings to try and figure out the problem: If we look at a Here-String, you’ll notice it is literally a long string. It has an array count of 1 but a large length. The question is, how can I access the i...
PowerTip: Set the color of the progress bar with PowerShell
Summary: Use the $Host object to alter the color of the progress bar in PowerShell. I was curious if there’s a way to change the color of the progress bar in PowerShell.

To change to a bright green background with a black foreground, use the following code in PowerShell: $Host.PrivateData.ProgressBackgroundColor=’Green’ $Host.PrivateData.ProgressForegroundColor=’Black’
Build a hexadecimal clock in PowerShell – Part 4
Summary: Use PowerShell to navigate the neutral zone. Honorary Scripting Guy, Sean Kearney, is here today to continue forth (not COBOL nor even Visual BASIC) into our silly yet fun quest to build a hexadecimal clock by using the PowerShell console. It does seem silly, doesn’t it? Yet, consider some of the things that we’ve learned in PowerShell during our quest. So, although the quest seems silly, we have learned quite a bit. Actually, it's much like any quest. The goal isn’t the point. It’s what you learn or experience while getting there. Our next part is to figure out how to draw this silly thi...
PowerTip: Set a default value in a switch statement
Summary: Use the default field in switch statement to have an assumed value. I was playing with Select-String and would like to have it default to a value if none was trapped for. How can I do that? Just use the Default keyword, and you can have an assumed value in the script block. In the following example, the switch is listening for the $DogSeesSquirrel object. If no values match, it returns ‘Squirrel runs free’. { 'Back door' { $Response=’Bark!’} 'Couch' { $Response=’Growl a bit.’} 'Food bowl' { $Response=’Bark! Bark! Bark!’} Default { $Response=’Squirrel runs free’ } } My apologies to our little d...
Build a hexadecimal clock in PowerShell – Part 3
Summary: Use Select-String in PowerShell to identify data and match it to an array. Honorary Scripting Guy, Sean Kearney, is here today to play more with our funky, nerdy, cool hexadecimal clock. Yesterday we built out a small function named Get-HexTime to give us the current time that displays hex digits instead of decimal for hours, minutes, and seconds. One of our challenges is going to be matching up the individual hex digits to our positions in the array. We can step through the list of characters in HexTime with a pretty simple loop: $Hextime=Get-Hextime For ($Count=0; $Count -lt ($HexTime.Length); $Coun...
PowerTip: Use PowerShell to identify a leap year
Summary: Use PowerShell and Math to identify a leap year. Is there a way to use PowerShell to identify whether this year is a leap year? Actually there is! You can use a combination of Get-date to find out the year and the Modulus function in PowerShell. If the value is zero, the current year is a leap year!
Build a hexadecimal clock in PowerShell – Part 2
Summary: Manipulate string data from Get-Date in PowerShell. Honorary Scripting Guy, Sean Kearney, is here today to have a little more fun with our silly project to build a hexadecimal clock in the PowerShell console. Well, after all, who said scripting wasn’t allowed to be fun? That’s usually how I learn, by playing about! Yesterday, we defined a cool array of Here-Strings that contain all the characters that we’d like to display in our clock. Today, we’re going to access the properties of the current time and see how we could put that to use. The very first thing that we’ll need to do is pull up the date an...

Build a hexadecimal clock in PowerShell – Part 1
Honorary Scripting Guy, Sean Kearney, is here today, and I’m going to sit down and have some fun this week. Today I was feeling a bit bored and, for some reason, the thought “hexadecimal clock” entered my head. Don’t ask why because I’m not quite sure about the “Why” part. But, it just did. Then, I sat down and thought, what’s involved? Really? As a script, from a pseudo-code standpoint, it’s pretty simple Only I wanted this to be…well…b-i-g. In my head, I wanted a clock as wide as my console. That started my head spinning. “Big letters. How can I draw big letters and numbers?” In the “old world” ...

I guess what I am really wishing is that I had either more Windows PowerShell cmdlets or a way t...

The Microsoft Scripting Guy, Ed Wilson, is still missing in action. He downloaded Windows 10, and I haven’t seen him since. So I thought I would write about getting Windows PowerShell 5.0 running on Windows 10. The first thing I need to do is find Windows PowerShell 5.0. I type PowerShell in the Web and Windows search box on my task bar. Cortana comes up and locates the Windows PowerShell 5.0 executable. I click the top of the list for the Desktop...

Ed is somewhere playing with Windows 10, and he left me on my own to upgrade my computer. He says it will be a good experience for me. I am not sure what he really means by that. But I am quite confidant that I can do this, and it will be a good experience. Step...

What’s My PID?
Summary: Ed Wilson, Microsoft Scripting Guy, creates a function to capture the process ID of a Windows PowerShell host. Microsoft Scripting Guy, Ed Wilson, is here. One of the things I like to know is the process ID (PID) of specific processes. Often this is trivial. I can use the Get-Process cmdlet and, for example, look to see what the process ID of Notepad.exe is. But what if I have four or five instances of Notepad running? Then it becomes somewhat an exercise in trial and error. This is also true for Windows PowerShell. For example, the Windows PowerShell console process name is PowerShell. No problem. Excep...
PowerTip: Find Most Recent Event Log Entry
Summary: Use Windows PowerShell to find the most recent event log entry. How can I use Windows PowerShell to see the most recent event log entry from my application log? Use the Get-EventLog cmdlet and select the application log and the Newest 1 entry: Get-EventLog application -Newest 1
Launch Elevated PowerShell Shell
Summary: Ed Wilson, Microsoft Scripting Guy, talks about launching an elevated Windows PowerShell shell. Microsoft Scripting Guy, Ed Wilson, is here. Today I had a great talk with Steve, the Scripting Manager. One of the things we talked about was the importance of community, and how the Windows PowerShell community seems to be really engaged with the Windows PowerShell team and with other documentation efforts. One of the great things that I love about the Windows PowerShell community is the interaction I have with them at user groups, conferences, and community events (such as the Atlanta TechStravaganza that i...
PowerTip: Use PowerShell to Check Logon Server for Client
Summary: Use Windows PowerShell to check the logon server of your clients. How can I use Windows PowerShell to verify if my users are trying to sign in to their computers with a Windows account instead of using their domain credentials? Check the value of the environmental LOGONSERVER variable: $env:LOGONSERVER If it reports \\MicrosoftAccount, they are using their Windows account to sign in instead of domain credentials.

Use Function to Determine Elevation of PowerShell Console
Summary: Ed Wilson, Microsoft Scripting Guy, talks about using a function to determine if a Windows PowerShell console is elevated. Microsoft Scripting Guy, Ed Wilson, is here. I had a friend tell me that nearly half of all the cmdlets, functions, and whatever’s in Windows PowerShell 4.0 on Windows Server 2012 R2 required elevation to Admin rights. I can neither confirm nor deny this assertion, and I have not seen any official documentation about this. But I can tell you, that there are quite a few of these things that do require elevation. For example, the Hyper-V functions (even in Windows&...

Describe Your PowerShell Variables
Summary: Ed Wilson, Microsoft Scripting Guy, talks about adding a description to variables. Microsoft Scripting Guy, Ed Wilson, is here. There is a “water feature” outside that keeps running and running and running. It is a bit strange, and to be honest, it makes me think that it is raining all the time. In central Florida in the summer, it is generally a safe bet that it will rain, but even when the sun is outside, without a cloud in the sky, the giant frog keeps spitting water into a pond. I don’t get it. It is not relaxing like a Zen pond, and it does not keep bugs at bay like a real frog wou...
PowerTip: Open Temporary Copy of PowerShell Profile
Summary: Open a temporary copy of your Windows PowerShell profile. How can I look at a temporary copy of my Windows PowerShell profile to ensure that I don’t accidentally make any changes? Copy your Windows PowerShell profile to a temporary file, and then open it in the Windows PowerShell ISE, for example: Copy-Item $PROFILE $([io.path]::GetTempFileName()) -PassThru | % { ise $_.fullname}
Weekend Scripter: Back Up Your PowerShell Profile
Summary: Ed Wilson, Microsoft Scripting Guy, talks about automatically backing up your Windows PowerShell profile. Microsoft Scripting Guy, Ed Wilson, is here. My rule for making backups is that when the loss of the item would cause me grief, it is backed up. Otherwise, there is not too much need for a backup. This includes things that are not related to computers in addition to computers, files, and Windows PowerShell profiles. For example, if I go on a trip and I only have a single battery for my camera, would I be upset if that battery dies, drains, or otherwise becomes useless? Maybe. But then again, maybe no...

Weekend Scripter: Replace One PowerShell Function with Another
Summary: Ed Wilson, Microsoft Scripting Guy, talks about replacing one Windows PowerShell function with a different one. Microsoft Scripting Guy, Ed Wilson, is here. One of the problems with writing Windows PowerShell code every day is that you eventually... No, it’s not what you think. I am often asked if I run out of ideas, and the answer is, "No, I don’t." There is so much I can do with Windows PowerShell that, in fact, a new version of Windows PowerShell will be out before I ever run out of ideas of what to do with the last version. No, the problem is not that I run out of ideas, but it is that I often fo...

Two Cool PowerShell Functions
Summary: Ed Wilson, Microsoft Scripting Guy, talks about a pair of cool Windows PowerShell functions to add to your profile. Microsoft Scripting Guy, Ed Wilson, is here. At times, it seems like a Windows PowerShell profile is like a filing cabinet. Whether you have good organizational skills or you organize in a more ad-hoc, random, fashion is a matter of choice—as long as your organization is effective. Today, I want to share a pair of Windows PowerShell functions that are in my Windows PowerShell profile. I believe that I copied them when June Blender and I team-taught a Windows PowerShell class for docum...

Sorting PowerShell Transcript Files
Summary: Ed Wilson, Microsoft Scripting Guy, talks about creating a sortable transcript name. Microsoft Scripting Guy, Ed Wilson, is here. One of the great things about Windows PowerShell is that if there is something that annoys you, you can generally fix it. Don’t get me wrong, Windows PowerShell is great, but like any program, there are things that annoy me. It is partly because I have different needs than a typical user—I have never been typical in my life. For example, I think that all of the defaults in Windows Explorer are wrong for me. For example, I want to see file extensions, I want to see ...
PowerTip: Determine if Running in PowerShell Console
Summary: Determine if you are running inside the Windows PowerShell console. How can I find if I am running inside the Windows PowerShell console for my Windows PowerShell profile?

PowerShell Profile? Which One?
Summary: Ed Wilson, Microsoft Scripting Guy, talks about determining which Windows PowerShell profile to use for which functions. Microsoft Scripting Guy, Ed Wilson, is here. Living in central Florida can be a bit warm and humid in late July. Of course, I knew that before we moved here. I told one of my friends recently, when he commented on the heat and humidity, that it was truth in advertising. I told him if the Scripting Wife survived July and August here, she would know that she could handle the worst of the summer weather. Interestingly enough, on many days recently, it has actually been warmer back in Char...

All About PowerShell Profiles
Summary: Ed Wilson, Microsoft Scripting Guy, talks about Windows PowerShell profiles. Microsoft Scripting Guy, Ed Wilson, is here. Today I am heading back to the basics. Why? Because my hard disk drive died, and I had to order a new drive to replace it. It gave me a good chance to reinstall Windows 8.1. Now, my laptop is really fast. It is amazing how dramatically the stuff that you install slows down your laptop. Even when you uninstall stuff, most programs leave components behind, so my poor laptop bogs down like a tractor in a muddy field. I didn’t lose any data because I sync everything on a regul...
PowerTip: Find Tangent of 45-Degree Angle with PowerShell
Summary: Find the tangent of a 45-degree angle with Windows PowerShell. How can I use Windows PowerShell to obtain the tangent of a 45-degree angle? Use the Tan static method from the [math] class, for example: [math]::tan(45)
Weekend Scripter: Building Test Servers
Summary: Ed Wilson, Microsoft Scripting Guy, talks about building test servers. Microsoft Scripting Guy, Ed Wilson, is here. This morning I am listening to my favorite Swiss classical radio station on my computer, and I am sipping a cup of herb tea. I have a nice strawberry scone that I picked up in town at a local bakery. I am reminded of a conversation I had with a friend of mine who was a TAM in Zurich. We were talking about testing changes prior to implementation. In the old days, having a test network meant building racks of servers, restoring tapes, and trying to keep track configurations in sync with produ...

Weekend Scripter: Break in to a Script via a Command
Summary: Ed Wilson, Microsoft Scripting Guy, talks about using the debugger to break in to a script via a specific command. Microsoft Scripting Guy, Ed Wilson, is here. One of the cool things, when troubleshooting a specific function in Windows PowerShell, is to set a breakpoint to occur each time the command is called. Remember, Windows PowerShell functions are also Windows PowerShell commands, just as language statements and cmdlets are. To set the breakpoint in a command, you use the -command parameter. You can break on a call to a Windows PowerShell cmdlet, function, or external script. You can use aliases wh...
PowerTip: Set PowerShell Breakpoint Based on Variable
Summary: Set a Windows PowerShell breakpoint based on a variable. How can I enter the Windows PowerShell debugger when a particular variable is accessed in a specific Windows PowerShell script?

Setting a Breakpoint on a Variable
Summary: Ed Wilson, Microsoft Scripting Guy, talks about using variable breakpoints with the Windows PowerShell debugger. Hello Windows PowerShell scripting dudes and dudettes! Debugging Week continues, and today I am talking about using variable breakpoints with the Windows PowerShell debugger. Setting a breakpoint on line 1 of the script is useful for easily entering a debugging session. Setting a breakpoint on a variable can often make a problem with a script easy to detect. This is, of course, especially true when you have already determined that the problem is with a variable that is getting assigned a value...
PowerTip: Find All Disabled Breakpoints in PowerShell
Summary: Find all disabled breakpoints in a Windows PowerShell session. How can I use Windows PowerShell to see what breakpoints are disabled in my current session?

PowerShell Cruise announced
SUMMARY: The Windows PowerShell Cruise, PowerShell on the high seas, is announced What's better than a vacation? How's geeking out about PowerShell (and other technologies) with a bunch of MVPs and doing that, in the Bahamas? I'm Doug Finke, 7 time PowerShell MVP and author or "PowerShell for Developers". Earlier this year people in the PowerShell community asked about organizing an all PowerShell event or conference in the Northeast. In thinking about it, I hit on the idea of why not do a conference on a cruise. I told Jeff Langdon, he was one of the people I was in touch with about doing a large event around Po...
Use PowerShell Strict Mode for Debugging
Summary: Ed Wilson, Microsoft Scripting Guy, talks about using strict mode in Windows PowerShell for debugging purposes. Microsoft Scripting Guy, Ed Wilson, is here. One of the cool things about Windows PowerShell is that it can take being ignored or being used carelessly and sloppily, and it still seems to work fine. I mean, in the old days with VBScript, it was common to use Option Explicit to force you to declare all of the variables that you were going to use in the script. In Windows PowerShell, no one seems to do this…at all. The bad thing is that if I run a script (say in the Windows PowerShell ISE)...
PowerTip: Enable Script Tracing in PowerShell Functions
Summary: Enable script tracing into and out of Windows PowerShell functions. How can I trace my script execution into and out of Windows PowerShell functions? Use the Set-PSDebug cmdlet and set a trace level of 2: Set-PSDebug -Trace 2
More PowerShell Script Tracing and Strict Mode
Summary: Ed Wilson, Microsoft Scripting Guy, talks more about Windows PowerShell script tracing and enabling strict mode. Microsoft Scripting Guy, Ed Wilson, is here. It can be somewhat painful to troubleshoot intermittent errors with Windows PowerShell. Two things that can lead to this are variables that do not get initialized properly (and therefore their values change over subsequent running of the script) and functions that do not get accessed properly. To solve both of these problems, we can use Windows PowerShell cmdlets. Yesterday in Tracing the Execution of a PowerShell Script, I introduced the tracing le...
PowerTip: Use Cmdlet to Trace Script Execution
Summary: Use a Windows PowerShell cmdlet to trace script execution. How can I trace lines that execute in a Windows PowerShell script, without concern for variable assignments, functions, or external scripts? Use the Set-PSDebug cmdlet and set a trace level of 1: Set-PSDebug -trace 1

When I see a script that doesn’t work, I think, "Cool…it is easy to troubleshoot." Often this is the case because the error message helps locate the source of the error. But if a script simply doesn’t work, it can be more diffic...
PowerTip: Find All Breakpoints in PowerShell Session
Summary: Find all breakpoints for a Windows PowerShell script. How can I see the debugging breakpoints that are set in my current Windows PowerShell session? Use the Get-PSBreakpoint cmdlet.
Weekend Scripter: Debug, Boss…Debug
Summary: Ed Wilson, Microsoft Scripting Guy, talks about debugging Windows PowerShell scripts. Microsoft Scripting Guy, Ed Wilson, is here. One of the cool things about central Florida is there are lots of farmers markets… especially (I am told) this time of the year. This is great, because I prefer organically grown, locally sourced food. I mean, I like my food to be simply food—not food and a whole lot of additives and other things. My simple rule is this: If I cannot read and pronounce it, then I won’t eat it. Although I have taken many science classes at the university, I have not had a che...

Summary: Ed Wilson, Microsoft Scripting Guy, talks about if you should write Windows PowerShell scripts or do something else. Microsoft Scripting Guy, Ed Wilson, is here. It is the weekend, and once again, it is a beautiful sunny morning in central Florida. I am sitting outside with my Windows Surface Pro 3, and taking the time to do a little writing. I picked up some fresh bagels, and I am sipping a nice cup of English Breakfast tea with a bit of lemon in it. As I reflect back over this week’s blog posts, I think I need to clarify one thing: the whole point of scripting is to make things easier. If it is e...

Only when it is really long? Or when it does complicated stuff? I don’t know if I have ever written an advanced function, do you? —BB Hello BB, Microsoft Scripting Guy, Ed Wilson, is here. Awesome day! I just received my copy of Blain Barton’s new book, Microsoft Public Cloud Services: Setting up your...

Fun with PowerShell Functions
Summary: Ed Wilson, Microsoft Scripting Guy, talks about basic design considerations for Windows PowerShell functions. Hey, Scripting Guy!

A PowerShell Script Is…
Summary: Ed Wilson, Microsoft Scripting Guy, talks about creating and using a Windows PowerShell script. Microsoft Scripting Guy, Ed Wilson, is here. This afternoon, it is raining—actually more like a thunderstorm because there is lightning and thunder. In the afternoon in central Florida, there is a really good chance that for 10 or 15 minutes, one will see an awesome thunderstorm. I think the weather people always have a standard line: "Chance of afternoon thunderstorms"—and there is a good chance they will be right. Anyway, listening to Beethoven and watching a thunderstorm is awesome. I even decid...

Summary: Use Windows PowerShell to display the current time in 24-hour format. How can I use Windows PowerShell to display the current time in 24-hour format? Use the Get-Date cmdlet and the –UFormat parameter with %R: Get-Date -UFormat %R
PowerShell Scripting: The Terms
Summary: Ed Wilson, Microsoft Scripting Guy, talks about Windows PowerShell scripting terminology. Hey, Scripting Guy! So I am confused, and I am not afraid to admit that I am confused. In the old fashioned VBScript days, I wrote scripts. I could also write subroutines or functions. And that was about it. Pretty simple, and it made sense to me. But with Windows PowerShell, it seems that there is so much more, and I do not even know where to begin. Not to mention that I have not seen a single reference about how to create a subroutine in Windows PowerShell. What gives? Can you throw me a bone? —JT &nbs...

Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to display a progress bar while counting the number of words in Word documents. Microsoft Scripting Guy, Ed Wilson, is here. One of the things that a writer does is keep track of words. This is not so much because one gets paid by the word (although in the past that was actually true, and it is still true for some magazines).

It goes to the production budget, it goes to planning for shelf space in bookstores, and it influences the cost...

Weekend Scripter: Use PowerShell to Create Folder
Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to create folders. Microsoft Scripting Guy, Ed Wilson, is here. I am not a huge fan of using a mouse. In fact, the more things I can do from Windows PowerShell the better. It is a huge waste of time for me when I have to remove my hands from the keyboard, chase down a mouse, mouse around for a while, and then return my fingers to the home row on the keyboard. One cool thing is that Microsoft Word has a number of keyboard shortcuts—of course, it also has an API. I also do quite a bit of scripting for that. Another place where I...

Weekend Scripter: Avoid PowerShell Scripting—Use GUI Tools
Summary: Microsoft Scripting Guy, Ed Wilson, talks about exporting queries from the event log tool. Microsoft Scripting Guy, Ed Wilson, is here. It has long been a truism (at least with things related to computers): powerful is opposite of simple. I can have a tool that is powerful, but with that power comes complexity. When that complexity is so complex as to render the tool ridiculously hard to use, the tool rapidly becomes useless. What is awesome is when a tool is extremely powerful and also very easy to use. Of course, this usually means that the tool makes lots of default choices for me. If those default ch...

Don’t Script: Edit PowerShell Command History
Summary: Microsoft Scripting Guy, Ed Wilson, talks about editing the Windows PowerShell command history. Hey, Scripting Guy! I liked your ideas in Avoid Scripting: Use PowerShell Command History. My problem is that I seldom (if ever) type commands perfectly the first time—often, not even the second time. This means that I end up with a lot of junk in my command history. I wish there was a way to clean up the command history so it would be more usable. Is there? —AP Hello AP, Microsoft Scripting Guy, Ed Wilson, is here. This afternoon, I am listening to a Canadian rock group and sipping som...

Avoid Scripting: Use PowerShell Command History
Summary: Microsoft Scripting Guy, Ed Wilson, talks about avoiding Windows PowerShell scripting by using command history. Hey, Scripting Guy! I used to have a program that I could use to keep track of commands I typed at the command prompt. It permitted me to use macros to replay those commands or to select which commands I wanted to run. It was simple, elegant, and not complicated. It is a shame that “modern” programs are not that easy to use. I really don’t relish the thought of having to learning scripting to be able to run a few commands. I wish I could go back to my old command prompt....

Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell and WMI to retrieve process owner and other information. Microsoft Scripting Guy, Ed Wilson, is here. We were supposed to receive seven inches of snow the other day.

Of course, the century is still not all that old, and the storm was not that big of a deal. In fact, as it turned out, it really was not a big deal at all. We received less than a half-inch of snow, and even that did not s...

Use WMI and PowerShell to Work with Services
Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell and WMI to work with services. Microsoft Scripting Guy, Ed Wilson, is here. It is that time of the year. I just spent the last couple of hours uninstalling useless software from my laptop. This includes stuff that I intentionally installed and junk that becomes installed with other programs. I also spent a decent amount of time reviewing start-up programs and services. This is pretty much a stop gap measure – it is only a matter of time before I FDISK my machine and perform a complete reinstall. It still seems necessary to rei...

Comparing WMI and Native PowerShell
Summary: Microsoft Scripting Guy, Ed Wilson, talks about comparing WMI and using native Windows PowerShell. Microsoft Scripting Guy, Ed Wilson, is here. When Windows PowerShell was still in beta, there was a saying (song?) that said there must be 50 ways to stop a process. Actually, I am not certain it was ever turned into a Windows PowerShell song, but it probably could have been. Anyway, the conversation was a reflection of the many ways of doing things that are available in Windows PowerShell…and that was back in the Windows PowerShell 1.0 days. Today, there are even more ways of doing things. So w...

Use PowerShell to Count Comments in Word Docs
Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to count comments in Microsoft Word documents. Microsoft Scripting Guy, Ed Wilson, is here. The process of writing often includes rewriting. In fact, I imagine that I spend more time rewriting stuff than I spent writing the original document—especially when I write a book.

Use PowerShell to Add Headers to Word Documents
Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to add headers to Microsoft Word documents. Microsoft Scripting Guy, Ed Wilson, is here.

Weekend Scripter: Control Processes with PowerShell
Summary: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to control processes. Microsoft Scripting Guy, Ed Wilson, is here. This morning I am made a pot of Masala Chai. I found a pretty good recipe when I was doing a Bing search: Indian Masala Chai.

Better PowerShell History Management with PSReadLine
Summary: Microsoft Scripting Guy, Ed Wilson, talks about using PSReadLine to gain better history support in Windows PowerShell. Microsoft Scripting Guy, Ed Wilson, is here. Someone might have said that those PowerShellers who do not learn how to use command history are doomed to retype the same commands, but I do not recall ever hearing it. In Windows PowerShell there are five *history cmdlets. Of these, I routinely use Get-History (the alias is h) and Invoke-History (alias is r). To be honest, I do not even use these all that often. One reason, is that the history eventually gets jumbled. Although it is possible...

Creating an XML Document for Admins
Summary: Microsoft Scripting Guy, Ed Wilson, talks about creating XML files. Microsoft Scripting Guy, Ed Wilson, is here. I will be the first to admit that I am not a huge fan of XML. I mean, if I can use a CSV file to store and retrieve the information I need, why do I need XML? Well, there are many times when the nested structure of XML is a more robust option. When dealing with objects inside of objects, a CSV file breaks down. In addition, reading a CSV file is a bit cumbersome when I need to look at the actual CSV file in something like Notepad. For XML, there is Notepad and XML Notepad. XML Notepad XML Note...

Understanding XML and XPath
Summary: Microsoft Scripting Guy, Ed Wilson, explores XML and XPath. Microsoft Scripting Guy, Ed Wilson, is here. One of the things that confused me for a long time about using the Get-WinEvent cmdlet is the difference between the –FilterXPath parameter and the –FilterXml parameters.
