College Name: Farmingdale State College (SUNY)      

Assignment Goals: To learn to use UNIX/Linux utilities and commands to process data in text files.

Tasks:

1. In your home directory, make a directory called hw2 and change to the hw2 directory.
2. Use the vi editor to create a file named students which contains the following text (The fields of the record are student ID, student last name, first name, and course ID):

   S001:Jones:Nancy:C410
   S004:Mitchell:Barbara:C206
   S003:Lieberman:Timothy:C304
   S005:Moore:Sarah:C203  
   S002:Polk:Christian:C101  
   S006:Jacobs:Paula:C203  
   S005:Moore:Sarah:C304 
   

3. Use the vi editor to create a file named instructors which contains the following text (The fields are the instructor’s last name, first name, course ID, and course name):

   Brown:Alice:C203:Java Programming
   Calvin:David:C101:Introduction to Computers
   Capra:John:C304:Algorithms
   Drew:Justin:C301:Data Structures
   Miller:Richard:C206:Computer Networks
   Sanders:Selina:C410:Computer Architecture    
   

4. Write commands to combine the above two files and generate a file student_instructor that contains student’s ID, last name, first name, course ID, course name, instructor’s last name and first name. Hints: Identify the common field of the two files. Sort each file on the common field and save the result to a new file. Use the join command to combine the two sorted files.
5. Output the contents of the student_instructor file on the screen. Hints: Use the echo command to output a prompt or an empty line.
6. Sort the file student_instructor in the order of student ID and output the result to the file report.
7. Output the contents of the report file on the screen.
8. Use the awk command to output from the file report the student ID, student’s first name and last name, course ID, course name, instructor’s first name and last name in a neat format on the screen.
9. Add a command to output “I certify that this submission is my own original work -- ” followed by your full name on the screen.
10. Use the vi editor to create a script called hw2script that has all your commands in step 4 - 9.
11. Add the execute permission to the owner, group, and others for your script file.
12. Run your script.

Submission:

Submit a word or pdf document that includes the following two screenshots:

1. A screenshot of the contents of your script file, i.e., after running the command vi hw2script or cat hw2script
2. A screenshot of the output of running your script file, i.e., after running ./hw3script.

Sample output after executing the script:
