Prerequisite Skills:
Expected Outcomes for Students:
Upon completion of the course, the students should be able to:

  1. display a basic knowledge of UNIX operating system capabilities, history, evolution and identify major variants;

  2. differentiate capabilities of a multi-user operating system, UNIX, from those of a single user system such as Windows 95/98/NT;

  3. identify the components of a UNIX system: file system, utilities, shell (command interpreter), kernel;

  4. use Unix commands to log on and off a UNIX system and change passwords;

  5. use Unix commands to manage files and directories;

  6. identify various UNIX shells, identify the login shell and recognize shell variables;

  7. redirect input and output, pipe commands, and run commands in the background;

  8. use (in a basic way) tools such as grep, find, cut, paste, join, sort;

  9. send, read and manage electronic mail;

  10. use the vi and/or emacs editors;

  11. edit, compile and run a simple C program under UNIX;

  12. identify, locate, and use UNIX-based Internet resources.

Methods of Evaluating Student Progress:

  1. Typical Assignment

    1. Create and compile a C program that allows a user to enter integer quantities for an elementary order entry invoice application computing quantities ordered, subtotals, and a grand total.

    2. Using the scripting capabilities in UNIX/LINUX, create an application that will allow a user to scan their account and list all subdirectories automatically, allow the user to select a subdirectory, display all files in that subdirectory. Keep looping until user chooses to quit
