When we create a file or folder on a Unix-based system like Linux or MacOS, it has a set of permissions and access modes. These are most often manipulated using the chmod command, which allow us to change who can access and run different files.
Let's look at how chmod works. To begin, the chmod command has the following syntax, where [OPTIONS] are optional settings, [MODE] are the permissions we want to give the file or folder, and x is the file we want to apply chmod to.
