sudo in Ubuntu

What is sudo ?

  • The sudo command gives some admin privileges to non-admin users
  • SUDO is similar to UAC in Windows

Why sudo ?

  • Certain Linux applications require elevated privileges to run. 
  • So either the user can switch user using su command or perform sudo and run the command
  • Linux uses the sudo command as a wall between normal tasks and administrative ones

  • /etc/sudoers file
  • This file can be edited using visudo editor only


Configuration file :

vi /etc/sudoers
cd /etc/sudoers.d/
