Calling a PowerShell script

PowerShell scripts are nothing but a series of PowerShell cmdlets, each in a line of a ps1 file. These instructions are executed one after the other, similar to the good old shell script. Using Visual Studio Code makes running PowerShell scripts simpler, in that you simply have to run the script to make the script work its magic.

However, running PowerShell scripts on Visual Studio Code is not the usual way of automation for obvious reasons. Also, there are many ways to run a PowerShell script. We shall look at a very simple way of running the script in this recipe; as we progress in this book, we will also add more features to our scripts and, further, will package them into modules for future use.
