What is Sudo?
Sudo (superuser do) is a utility for UNIX- and Linux-based systems that provides an efficient way to give specific users permission to use specific system commands at the root level of the system. In Ubuntu Linux, the root account is not configured by default. If users want a root account password, they must set it up manually to use “sudo.” Using sudo is a good way to protect the user’s computer from being used as a tool for exploitation. Whenever users try to install, remove, or change any piece of software, they must have the root privileges to perform such tasks. The sudo command is used to give such permissions to any command that a user wants to execute once the user enters a user password to give system-based permissions. Sudo also logs all commands and arguments that are executed.
