PowerShell Script Module Design: Public/Private versus Functions/Internal folders for Functions

9
There's been a lot of debate about script module design as of lately and instead of tweeting something out asking for responses, I thought I would post it here via a blog article. Back when I first started creating PowerShell script modules, I placed all of my functions in the PSM1 file and later started placing each function in a separate PS1 file that was dot-sourced from the PSM1 file. I would simply place the PS1 files in the root folder of the script module. Read more [...]

Determine the Day of the Week in 11 Days from Now with PowerShell

0
A couple of days ago, one of my kids asked me "What day of the week will it be in 11 days from now?". My response was "I'm not sure, but I can tell you how to figure out the answer for yourself". Open up PowerShell, wrap Get-Date in parentheses, place a dot or period afterwards, followed by AddDays,  then 11 in another set of parentheses, and finally another dot or period followed by DayOfWeek. Want to know what the day of the week was 11 days ago instead? Read more [...]

PowerShell Saturday Chattanooga Post-Mortem

PowerShell Saturday Chattanooga was this past weekend. I attended the all-day preconference presented by Jeff Hicks on Friday which saw a great turn out of about 50 people or so. I presented two 45-minute sessions as part of the Saturday event. One on "Writing award winning PowerShell functions and script modules" and another on "Recreate MOF based DSC resources as Class based DSC resources". The code and slide decks from both of my presentations can be found in my presentations repo on GitHub. Read more [...]

Determine if a Mailbox is On-Premises or in Office 365 with PowerShell

2
One of the companies that I support is currently in the process of migrating from an on-premises Exchange Server environment to Office 365. They're currently running in hybrid mode. While it seems like wanting to know what mailboxes still exist onsite versus which ones are in the cloud would be an all too common task, there doesn't seem to be an easy way to get that information with PowerShell. You would think that you'd be able to run a PowerShell command and it would return the results. Well, not Read more [...]

Displaying Toast Notifications for a Different User when PowerShell Module Updates are Available

1
A couple of months ago, Josh King presented a session on “Using BurntToast to Display Timely Notifications” for our June 2018 Mississippi PowerShell User Group virtual meeting. I was previously planning to write something to display balloon notifications in Windows and I learned that they're now called toast notifications. I also learned that Josh had created a module named BurntToast which performs most of the heavy lifting so I could simply take advantage of it instead of writing my own code. Note: Read more [...]

Use PowerShell to Determine What Your System is Talking to

13
Recently, while troubleshooting a problem with a newly installed application, I wanted to see what it was communicating with. My only requirement was that I wanted to use PowerShell if at all possible. I couldn't remember if there was a PowerShell command for accomplishing this task or not, but I remembered seeing something about it in Patrick Gruenauer's chapter (PowerShell as an Enterprise Network Tool) in The PowerShell Conference Book. Note: This blog article is written using Windows 10 version Read more [...]

Announcing the PowerShell Conference Book

5
A couple of months ago, I saw a tweet from Don Jones about how much it costs to sponsor one person for the OnRamp Scholarship Program. I replied wanting to know if the DevOps Collective had considered becoming part of the "Leanpub for Causes" program so that portions of an author's royalties could be donated to the program. My initial thought was that I could donate a portion of the royalties from my PowerShell 101 book to the program. A few days later Don copied me in a tweet saying he had Read more [...]

Use PowerShell to Install Windows Features and Reboot

0
Recently, I installed the Windows Subsystem for Linux (WSL) feature on my Windows 10 computer. Microsoft has an installation guide that walks you through the entire process, but I thought I'd share a few PowerShell tricks when it comes to installing Windows features. The system used throughout this blog article runs Windows 10 version 1803 which ships with Windows PowerShell version 5.1. Your mileage may vary if you're using a different version of Windows and/or PowerShell. Run Windows PowerShell Read more [...]

TechSnips is Looking for Content and Recruiting Contributors

1
This blog article is the first guest post ever on this site. When I'm approached by someone who wants to write a guest blog article, I suggest that they should start their own blog. If they're simply not interested in that, I put them in contact with PowerShell.org because it seems like a more appropriate place to publish community blog articles. The majority of the posts on this site are simply the steps of how I've done something in a real-world production environment. I document the process here Read more [...]

Convert Scientific Notation to Decimal with PowerShell

Have you ever run into a problem where the results from a PowerShell command are returned in scientific notation? I've recently been working with performance counters in PowerShell and I've run into several scenarios where this occurs such as the one shown in the following example. In addition to returning the results in the previous example, they were also stored in a variable so the same value could be used throughout this blog article. Windows PowerShell Read more [...]

Connect to Office 365 with PowerShell

I've recently been working on a project to migrate an Exchange Server 2010 environment to Office 365. As with Exchange, there are several things that simply can't be done from the GUI in Office 365. This means that if you're the Office 365 administrator for your company, you'll need a certain level of proficiency with PowerShell to effectively do your job . While not requirements, this blog article is written using Windows 10 Enterprise Edition version 1803 and PowerShell Core version 6.0.2. All Read more [...]
