Powershell Comments Examples

Like any other scripting or programming language, PowerShell provides comments to help make the scripts more readable and maintainable.

Below is a list of comments that are supported by Microsoft PowerShell with Examples.

  1. Single-Line Comment:

    Single-Line comments in PowerShell start with # hash sign.

    # Example of Single Line Comment in PowerShell
    $no = 20 # This is also a Single Line Comment.

  2. Multi-Line Comment:

    Multi-line commands start with <# and ends with #>

         This is an example of
         Multi-line comment in PowerShell.
         You can add as many lines as you 

Let's see a practical usage of both these types of comments with a real-world example.
