I need the commands for the following request, in debian 11

ii. Write a script that does the following: If the current user is a regular user, the script displays the last sudo entry in "auth.log" for that user. If the current user is the root, it requires one argument, which is the username for whom to display the last sudo entry in "auth.log". Sample execution: $ /usr/local/bin/last_sudo (or, \# /usr/local/bin/last_sudo john) Dec 2016:05:16 john-linux sudo: john : TTY=pts/0; PWD=/home/john/Desktop ; USER=root; COMMAND=/sbin/reboot Check arguments and show usage message if wrong arguments
