Part 1: Automated Account Management (3 marks)

You have been asked by your boss to prepare two shell scripts which manage user information:

You are to prepare a simple shell script which reads a text file called users.txt. The file is in the form

dfs /home/dfs Daniel Saffioti

and creates these users on the system without any interactive input. To do this you will need to use the adduser(1) and passwd(1) commands. You will need to randomly produce the password and report this to the administrator.

You can assume the fields being username, home directory and GCOS string are separated by a single white space.

You can assume all users are in the same group. The program should output the username and generated password once created.

Management of users is important particularly their removal. Write a shell

(.sh) script that takes a single argument being a username, looks for the account in /etc/passwd, deletes the accounts, and archives their home directory into a tar.gz file. You will receive more marks if you avoid using the standard user management tools.
