Switch users and sudo access

• Commands
  • su - username
  • sudo command
  • visudo (used to edit the sudoers file safely)
• File : /etc/sudoers

## Allows people in group wheel to run all commands
wheel  ALL=(ALL)       ALL

If we want a user to be able to execute sudo command, we can add them in the wheel group using usermod command (see User Account Management)

usermod -aG wheel userName
