Linux Utilities and Shell Programming
This three-day course provides a follow-on
from the Introduction to Linux
course for power users and administrators who wish to learn more of the
general purpose Linux utilities, and be able to automate tasks by
writing Bourne, Korn and Bash shell scripts. This course not only
teaches you the utilities and programming skills, but also provides
many
examples of useful shell scripts. A further important aspect is that
you
will be able to readily interpret existing scripts.
Our Linux courses are suitable training for Linux LPI or RedHat Certification

PREREQUISITES: Experience of Linux
similar to the level covered in our Introduction
to Linux course.
FOLLOW UPS: We offer two Linux
Systems Administration courses (Linux

need to tackle more advanced data manipulation and scripting techniques
should also consider our range of Perl
Programming courses. Sheets describing each of our courses, and
current schedules, are available on request.
PRACTICALS / TAKEAWAYS: Each student
leaves the course with their own set of training notes for the material
covered; around 120 pages per day of training.

will be issued with a signed certificate of course completion, which we
will be happy to "authenticate" upon future request. |
| On this course, we hand out a number
of quick reference sheets to each student on subjects such as vi and
Linux commands. |
| Students on this course can print out
their work and take it away with them. |
SOFTWARE VERSIONS: Uses the Redhat or
CentOS
Linux distribution, but is suitable for any version of Linux or UNIX..
