PowerShell – Multiline Comments

In PowerShell, use the # symbol at the beginning of a line to comment out a single line. Multiline comments in PowerShell can be easily achieved by using <# at the beginning of the line and #> at the end of the code.

The comment block of code is used to document the program to provide explanatory information about the code. PowerShell multiline comment out code summarizes the code.

In this article, I will explain how to comment out multiple lines of code in the PowerShell script and comment out a single line in PowerShell.
