Instructor course overview
This course has been designed from a user's perspective. The
students are not required to have any prior knowledge of AIX or any
other UNIX-based system.
The course sessions have been designed in a logical order to enable
the novice user to identify the major components of AIX. Then, the
students are introduced to the operating system by logging in and out
of the system and carrying out a few basic operations. The hierarchical
tree structure is explained in detail, and all the functions that can be
carried out on files and directories. The concept of a shell is introduced
and the operations that are supported through it. The one editor that is
covered is vi, this being the one that is available on most UNIX
platforms. The concept of users owning jobs and thus processes is
introduced, including the environment in which processes execute.
Finally, to pull together all the ideas from the previous units, a few
useful tools are introduced which help users customize their
environments and write very simple shell scripts, which is the main
objective of the course.
The course objectives and content are listed in this section. Ensure

that you cover both at the start of the course to set the correct
expectations right from the start.
Also note that all your students will have different levels of experience
with the operating system and also different capacities in learning. So,
it is very important to identify the level of your audience at the
beginning and only introduce additional information/discussion items
where relevant. The discussion items provided can usually be used to
challenge the more experienced students.
The main teaching aid that is provided with the course is the course
visuals. However, feel free to demonstrate any of the concepts
covered on demonstration workstations or in any other way, if you feel
that by doing so you will aid the learning process of the students.
Finally, remember that this course has been designed for users of the
operating system. System administrative concepts should not be
covered because they are outside the scope of this course. For
students who are interested in administrative tasks, encourage them
to attend the System Administration and the Advanced System
Administration courses. The System Administration course covers
how a system can be set up from a new installation, whereas the
emphasis for the advanced course is more on problem determination.

principals.
Italics Identifies links to Web sites, publication titles, and is used
where the word or phrase is meant to stand out from the
surrounding text.
Monospace Identifies attributes, variables, file listings, SMIT menus, code
examples of text similar to what you might see displayed,
examples of portions of program code similar to what you might
write as a programmer, and messages from the system.
Monospace bold Identifies commands, daemons, menu paths, and what the user
would enter in examples of commands and SMIT menus.
<text> The text between the < and > symbols identifies information the
user must supply. The text may be normal highlighting, bold or

monospace, or monospace bold depending on the context.

Notes:
The AIX Kernel
A computer consists of many hardware devices that the users of a computer system
want to use. For example, they want to print documents or they want to play a game
from a CD-ROM.

To control these hardware devices and to share them between multiple users, an
operating system must be loaded during the system startup. In the case of the AIX
operating system, there is one special program which interfaces directly to the
hardware devices: the AIX Kernel. The Kernel controls the access to the devices.
On the other hand, the users start different programs, for example, a program that prints
a document or removes a file. These programs that run in AIX processes are also
controlled by the AIX Kernel.
To say it simply: The AIX Kernel is the heart of your operating system.
