CU030 - Advanced UNIX Programming

Length: 5 Days

Description

Course Objectives

1. state the architecture of the UNIX operating system;
2. describe how a UNIX system is initialized and identify the various run levels;
3. use selected UNIX software development tools for program development and maintenance;
4. describe the logical and physical file system;
5. perform UNIX system commands which manipulate files and directories and control processes;
6. define processes and state how they are controlled;
7. describe the I/O subsystem to include block and character device and streams implementation;
8. describe the interprocess communications facilities;
9. write, compile, and execute C language programs which examine UNIX internal data structures and display information about processes, the file system, and kernel operations; and,
10. write and execute programs which illustrate the use of the UNIX pipe, messages, semaphores, shared memory, and signals interprocess communications facilities.
