Add Content To a File Using PowerShell

In this blog post, we will learn how to add new content to a file using PowerShell. In many use cases and situations, you might need to add a string or value to a TXT file without opening the file.


With the Add-content cmdlet, we can new content to an existing file without deleting or clearing the existing data that the file contains.


Let’s take a look at the below code and example which I start with creating a new file and then using the add-content to add value to the file without clearing the data file.

New-Item test.txt
Add-Content .\test.txt -Value "This is a test"
cat .\test.txt
This is a test

Go ahead and try and see how great the add-content cmdlet is and useful it can be in cases where a script or a process need to save data.

Success! You're on the list.
