Comprehensive AIX
| Duration: 5 days |
| Participants: Technical and non-technical personnel, including technical managers, programmers, system and network administrators. |
|
Objectives:
Upon successful completion of this course you will be able to:
- Organize and protect your own file and directory structure. - Create and modify files using the vi editor. - Select lines from files using the grep command and RE metacharacters. - Direct file input and output from/to the proper file or process using redirection and pipes. - Control the execution of foreground and background jobs. - Use shell command line features such as filename generation to perform work in an efficient manner. - Tailor the interactive environment by using aliases and variables established in .profile and the ksh ENV file. - Create shell programs using command and variable substitution, positional parameters, and control structures. (Please note that this part of the course is optional; as much is presented as time permits, however, most classes cover all of it.) |
| Overview: This course provides a comprehensive introduction to AIX, including programming with Bourne and Korn shells. It is designed for those who need a robust understanding of AIX. |
| Prerequisites: None. |
| Format: Lecture and discussion (50%) with interactive and programming exercises (50%). |
