CIT 052 - UNIX Shell Programming - Spring 2012 Evergreen Valley College

General Information

3 Units | CR | Prerequisite: CIT050 or equivalent

Course Description

CIT 052 is a course in UNIX shell programming using different shell programs available with the AT&T UNIX 5.0 operating system. The course will include use of Bourne Shell and C-Shell Programming theory and concepts. These concepts include interpretation of different quote characters, shell variables, decision-making commands, and looping mechanisms. Students will also learn passing arguments to shell scripts, I/O redirection, terminal/file I/O, subshells and using special UNIX commands. Additionally, this course will include use of restricted shell (rsh) and introduction to Korn shell commands.

Learning Outcomes

Upon course completion, students will be able to:

• Differentiate between the C, Korn, and Bourne shells
• Use meta-characters to apply shell commands to multiple files
• Direct output from one shell command to another
• Write, read, and use regular expressions in shell commands
• Use the grep command to search for text in files
• Use the stream editor (sed) to modify text files
• Use the awk utility to print selected fields in specific formats
• Use conditional expressions to select fields dependent upon their content
• Use loops to access and store data in arrays
• Use built-in functions to modify data
• Create his/her own functions to modify data
• Use these aspects of the Bash environment:
  • Use positional parameters in a command line
  • Construct shell scripts which use conditional and looping statements
  • Write and call user-defined shell functions
  • Modify shell environment variables

Process

This is an Internet class with regularly scheduled group discussions and times at an open lab on campus. The instructor will be present to assist you during the group discussions and the scheduled lab hours, but you may come any time the labs are open. You may work on assignments in the lab or use your own computers. Midterms and the final must be taken during the scheduled times.

Required Text

UNIX® Shells by Example, Fourth Edition, Ellie Quigley, Prentice Hall 2005 ISBN-13: 978-0131475724

Assignments

You will be assigned exercises ranging from light to moderate complexity. For each assignment, you will print the solution or email a file to the instructor. Do not put blanks in your file names. If you email files, send them as plain text only.

Assignments will be graded on functionality, organization, readability (which includes proper use of naming and Linux/UNIX conventions) and appropriate use of shell constructs.

Exams

You will have two midterm tests and one final exam, which must be taken on campus on 22 May 2012 from 6:00-7:30 p.m. (If you cannot be on campus at that time, make arrangements with the instructor.) This is a comprehensive final which covers all the topics in the course. You may use the book, your class notes, and man pages on these tests.

Grading

The work on the tests and exercises will be weighted and combined to calculate your final grade as follows:

Weight Lab Assignments: 60% Midterms: 20% Final Exam: 20%

Grading: 90% and above A 80% B 70% C 60% D Less than 60% F

Attendance

As this is in an Internet course, there is no compulsory attendance, except that you must take exams on campus. You are strongly encouraged to attend on-campus group discussions, and you may do lab work on campus if you wish. If you decide to drop the class, it is your responsibility to do so. If you miss more than five assignments, the instructor may drop you from the course. Save the printed drop confirmation! You may need it to confirm that you dropped the course, or you will receive a failing grade. The deadline dates for dropping a class with and without a “W” are in the Evergreen Valley College schedule.

Policies

Exercises are to be submitted prior to midnight on the date due. If turned in late, you will receive reduced credit; one letter grade per class session late up to two sessions late. Missed tests or exercises will receive zero credit. The final exam is required. Discussion about assignments is encouraged, but you must each do your own work. Cheating and plagiarism will be met with an F on the assignment. See the EVC catalog for details on the College Honesty Policy as well as student disciplinary and grievance procedures (pages 165-168).

If you have learning or physical needs that require special accommodations, please let an instructor know as soon as possible.
