UNIX Systems Course

Total Items: 6 Total Time: 39.00 hour(s)

Summary:

This training presents the features of UNIX that are most useful to new users, as well as system administration tasks and process management.

Basic features discussed include logging in and out, file administration, command processing, displaying text, and using mail. UNIX shells - Bourne, Korn, and C - are presented, including a comparison of their advantages and disadvantages, and writing basic shell programs that include repetitions, conditional statements, and functions.

Many system administration tasks are discussed, including installation, file systems, user accounts, system accounting, performance monitoring, device management, and security.

Advanced topics covered in the series include how to control UNIX programs, how to start and kill programs, and prioritizing processes.

 Learning Segment 6: Process Management

Summary:

This learning segment describes how to control programs in UNIX including how to start a job (program) and how to kill it.

Objectives:

• Describe how UNIX executes a command Define the use of processes Describe the advantages of background execution List three common daemon processes Monitor processes with ps and time Differentiate between foreground and background processes Kill processes Prioritize processes Tune the UNIX system with ps and sar Define and manipulate a crontab

Topics:

• What is a Process? Administering Processes Scheduling Processes

Features:

• Simulations teach learners to perform specific tasks in applications through guided, multi-step exercises.
• A Course Topics list contains active hyperlinks, permitting quick access to specific topics.
•  Find-A-Word allows learners to look up an unfamiliar term in the Glossary, on the Web, or in a dictionary. In addition, it lets them find other occurrences of the term in the same course.
• Search text enables learners to rapidly search all text within a course to easily retrieve information required.
• Courses challenge the learner with a variety of question formats, including multi-step simulations, true/false, multiple choice, and fill-in-the-blank.
• A skill assessment generates a customized learning path based on the results of a pre-test.
• A glossary provides a reference for definitions of unfamiliar terms.
• Bookmarking tracks the learner's progress in a course.
