Write a Bash script that takes a list of login names on your computer system as command line arguments, and displays these login names, full names and user-ids of the users who own these logins (as contained in the /etc/passwd file), one per line. If a login name is invalid (not found in the /etc/passwd file), display the login name and an appropriate error message. Do appropriate error checking.
Problem #3 [10 marks]
Write a Bash script that takes a directory name as a command line argument and clean the directory by removing all the files with a zero length, with a .tmp or with a .swp extension that is found in this directory (note that sometimes .swp and .tmp files are hidden). After the directory has been cleaned, create an archive of this directory and then compress the archive file and place it in your ~ directory. Do appropriate error checking.
Problem #4 (Putting it all together) [10 marks]

Use the solution-scripts in problems 1, 2 & 3 for menu selections a, b & c respectively. As such you do not need to re-write the solutions for those options, just use them to fulfill the requirements of selections a, b & c.
