Modify final. sh so that if you enter an argument on the command line called non_student_accounts you will display the number of accounts on the system that are not related to a student. Student accounts have a home directory in /home/student. Display the results with the following message. There are XX non-student accounts on YYY. Replace XX with the number of non-student accounts. Replace YYY with the hostname of the system. This information will come from a Unix/Linux command. Example: $ ./final. sh non_student_accounts Tim McGowen Mon May 20 09:58:28 PDT 2013 There are 17 non-student accounts on xyz. In the display above 17 and xyz are just examples. Not the correct answer. Test your script so that the non_student_accounts argument works correctly. When it does, continue.
