Creating Users and Groups

Linux is a multiuser OS, meaning that a single Linux computer can support many users, each with a unique account. With this capability comes the need to manage users’ accounts, and this chapter covers the procedures you’ll use to do so.

The chapter begins with information on how to create accounts. With the accounts created, you then need to know how to modify those accounts and, when necessary, delete them. Finally, groups are similar to accounts in many ways, so how to create and manage groups is described.

  • Creating new accounts
  • Modifying accounts
  • Deleting accounts
  • Managing groups
