Linux User Management

• useradd
  • Native binary compiled with the system
  • Creates only a user by default (you have to use switches) to specify home directories and other settings
• adduser
  • Perl script which uses useradd among others
  • More user friendly and interactive
  • Creates a fully functional user on the system by default
