In previous articles, we've covered how chmod works. In this article, we'll be covering how to use chown. chown is closely connected to chmod since it affects who owns a file, and which group it belongs to.
In our article on chmod we cover how different user types (i.e. owners, groups, and all other users) have different permission sets. That means who owns or in which group a file belongs, can affect who can run it, and might even affect if a system process can run or open a file.
