Answer / isha
allows users to run programs with the security privileges
of another user (normally the superuser).It is an
abbreviation for "switchuser do" (as in, do a command with
another user's privileges). By default, sudo will prompt
for a user password but it may be configured to require the
root password, or require it only once per pseudo terminal,
or no password at all.[3] Sudo is able to log each command
run and in some cases has completely supplanted the
superuser login for administrative tasks
