If you are curious as to which modules are missing, you can type Get-Module -ListAvailable. In other words, PowerShell 5 has twice as many modules as PowerShell 6 does. If you look at the screenshot below, you can see that while PowerShell 5 currently reports having 136 modules, PowerShell 6 only has 57 modules. Here are what the commands look like: $M = Get-Module -ListAvailable | Measure Rather than using the Get-Command cmdlet, we can use the Get-Module cmdlet with the -ListAvailable parameter. If you want to know how many modules are missing, you can use a technique similar to the one that I showed you a moment ago to find out. Not only are there a lot of cmdlets missing from PowerShell Core, there are entire modules missing. Keep in mind that this figure is based on the modules that are currently loaded, but both environments were running the same three modules (,, and PSReadLine). On the other hand, PowerShell Core includes only 2,589 cmdlets. If you look at the screenshot below, you can see that PowerShell currently includes 7,678 cmdlets. These commands count the total number of cmdlets that are available. If you want to know just how many cmdlets are missing, then enter the following two commands into both PowerShell and PowerShell Core. Hence, Hyper-V related cmdlets probably won’t be included in the Linux or MacOS versions of PowerShell Core.Įven in the Windows version of PowerShell Core, however, there are a lot of cmdlets missing (at least for now). For example, Windows PowerShell contains a large set of cmdlets for managing Hyper-V, but Hyper-V does not run on Linux or on MacOS. Some of the Windows-related cmdlets aren’t really applicable to other platforms. There are even versions of PowerShell Core that are designed to run on Arm processors.Īs nice as it may be to have a multiplatform version of PowerShell, it is important to remember that PowerShell was originally designed to be a management tool for Windows. The previously mentioned GitHub site includes download options for Windows, MacOS, and Linux. Unlike Windows PowerShell, PowerShell Core is multiplatform. PowerShell Core: Multiplatform - with a caveat In fact, it has a somewhat different purpose. PowerShell Core is more than just the next version of PowerShell. However, that is not going to be the case for PowerShell. Normally when Microsoft gives us a new version of a Windows component, the new version replaces the old version. PowerShell Core’s version information does not even describe it as “PowerShell Core,” but rather as PowerShell 6.1.3. The version of PowerShell that comes with Windows is 5.x. The PowerShell Core GitHub page almost makes it seem as though PowerShell Core is a third-party tool, but it is officially sanctioned by Microsoft.Īnother thing that you will probably notice in the screen capture is the version number. First, both PowerShell and PowerShell Core include copyright notices indicating that they are Microsoft creations. The most obvious difference between the two windows is the background color, but if you look a little more closely at the two windows you will notice some other details. The version of PowerShell that is included with Windows 10 is running in the window on the left, and PowerShell Core is running in the window on the right. If you look at the next screenshot, you can see what PowerShell core looks like. As you can see in the figure below, PowerShell core uses a simple installation wizard that is similar to that of most other Windows applications. Installing PowerShell Core is a simple process. You can download PowerShell Core from GitHub at this link. In contrast, PowerShell Core has to be downloaded and installed separately. That being the case, I wanted to take the opportunity to discuss the differences between PowerShell and PowerShell Core.Īs I’m sure you know, PowerShell is included with the Windows operating system and is installed by default. Although there are no signs that PowerShell is going away, Microsoft has been promoting a PowerShell alternative called PowerShell Core. PowerShell has been a significant component of the Windows operating system for many years now.
