PowerShell Core Commands

In this tutorial we will see about Windows PowerShell Core Commands. Below is the explanation provided by Microsoft for those commands.

PowerShell includes a set of cmdlets that are specifically designed to manage the items in the data stores that are exposed by Windows PowerShell providers. You can use these cmdlets in the same ways to manage all the different types of data that the providers make available to you.

Below we will see the list of those commands, what they do and and some examples.

Some Examples

Now we are going to see some examples of the first two categories of the above commands. As the above commands can be used in many ways, it is best to check each one of them separately to better understand their use. I not going to provide examples for each one of them in this tutorial. It will make the tutorial huge and full of screenshots, therefore it will be difficult to read.

There are different use cases that you can apply each one of them, in different ways and of course there are parameters that you can define their behaviour. The examples below are just simple ones, to help you get an idea of what you can do with them, there are much more things that you can do with the above commands.

If you want to check more about each command. I have provided you below, in related links section, the link of each command that directs you to Microsoft documents. There you can find a lot of information about the commands and their parameters including examples.
