Course Description

Introduces the UNIX/Linux operating system, including: task scheduling and management, memory management, input/output processing, internal and external commands, shell configuration, and shell customization. Explores the use of operating system utilities such as text editors, electronic mail, file management, scripting, and C/C++ compilers. Discusses trends in UNIX/Linux, including use of graphical user interfaces. Recommended: CS 160. Audit available.

Intended Outcomes for the course

On completion of this course the student should be able to:
Identify and use UNIX/Linux utilities to create and manage simple file processing operations, organize directory structures with appropriate security, and    develop shell scripts to perform more complex tasks.
Effectively use the UNIX/Linux system to accomplish typical personal, office, technical, and software development tasks.
Monitor system performance and network activities.
Effectively use software development tools including libraries, preprocessors, compilers, linkers, and make files.
Comprehend technical documentation, prepare simple readable user documentation and adhere to style guidelines.
Collaborate in teams on system tasks.

Outcome Assessment Strategies

Students will complete projects comprised of user documentation, message preparation, file preparation, manipulation and computerized reporting, script completion, C/C++ program implementation, and testing.

  • Documentation will demonstrate good organization and readability.
  • File processing projects will require data organization, problem solving and research.
  • Scripts and programs will demonstrate simple effective user interfaces.
  • Scripts and programs will demonstrate effective use of structured programming.
  • Scripts and programs will be accompanied by printed output demonstrating completion of a test plan.
  • Testing will demonstrate both black and glass box testing strategies.
  • Project work will involve group participation.

Students will demonstrate competency on exam(s) which are constructed to demonstrate:

  • Written technical communication and effective use of concepts and terminology.
  • Facility with Unix command syntax and semantics.
  • Ability to read and understand specifications, scripts and programs.
  • Individual capability in problem solving using the tools presented within the class.

Students will demonstrate a mastery of the course materials and concepts within in class discussions.
