Excerpt from the following site, on what is sudo:


sudo stands for "su do", and means "do something as the supervisor". `sudo` is an enhanced alternative to the Unix `su` command.

The `su` command allows any user to obtain superuser privileges, if they know the root password:
bash-2.05a$ su -
Password:
#

The Impact of sudo on Unix System Security
`sudo` improves on `su` in several ways:
`sudo` allows you to give privileged access to only some commands, instead of all commands.
`sudo` allows you to log all commands (and their arguments) executed as the privileged user.
`sudo` does not require the administrator to share the root password.
`sudo` allows you to limit the users who can use it by editing the sudoers file.
`sudo` times out after 5 minutes (by default).
