📄️ File and Directory Permissions

With GNU/Linux, all the files of the system belong to a user and a group. The owner of a file is the user who created it and the main group of this file is that of the user who created it. For example, in the other chapters, we worked with a user account simply called user. If this user creates a file, it belongs to the parrot user and the default group of the parrot user. For this reason, we often use the sudo command to be able to read, modify or execute files and programs of the system or make changes in the permissions of the files in question.
