Users

• Most UNIX systems are "multi-user"

  (Many users can log in at one time)
  

• There are three types of users:

  • Normal users (ericl, donny, etc)
  • The super-user: root
  • Standard Users (nobody, adm, uucp, etc)
    • System accounts are rarely used for logins.
    • Certain programs will run as these users
