The User Administration Tool Command-Line User Administration File Permissions

Ubuntu controls all access to files and folders with user accounts. If you're the only person using your Ubuntu workstation or server, then you won't have much need for this chapter. However, if you're in an environment where you have to control access for several users on a system, it's imperative that you know how Ubuntu handles privileges and how to create and manage user and group accounts. This chapter discusses the Ubuntu User Administration tool, the graphical tool for managing your system users and groups. It also discusses how to handle user and group management from the command-line prompt, in case you need to do that without the GUI tool. The chapter closes out by discussing how to manage user and group accounts to restrict access to files and folders and how you can use them to provide an access control environment for your Ubuntu system.
