Detailed information about this course

Linux - UNIX and the shell

'AT Computing organized an in company training Linux/Unix especially for our DBA engineers who wanted to dust their Linux and scripting knowledge.
AT Computing delivered a very well experienced Unix/Linux professional. He was very passionate about the topics and his teaching skills were fine.
When asking questions he was capable of understanding the issues directly and come up with ideas to solve these issues.
Documentation and other infrastructure and equipment were alright.
Attendees are unanimous in their judgement: Great course in particular because of the teacher.'

Once you grasp the taste of Linux/UNIX systems, the desire will come to do more than just lining up a sequence of commands. Scripting is the next step to go.

The shell is a command interpreter: your personal butler in the system. But it also is a full blown programming language, that allows entirely new commands to be constructed. Therefore, this shell programming language is a key ingredient of this course.

Apart from the shell, two more programmable utility programs will be covered. First the stream editor sed, capable of editing textual data as they flow by in a batch-like data pipe line. Then the programmable report generator awk, that allows for very complex operations on textual data, including the production of well-formatted output reports.

A few more smaller utility programs are part of this course as well.

Prerequisite knowledge

Basic knowledge of the Linux/UNIX user level command repertoire, and some experience in using these commands. Knowledge of the I/O redirection mechanisms, file path naming conventions, and the file name wild card notation. Basic knowledge of the regular expression language.

This prerequisite knowledge can be obtained via our Linux UNIX part 1 course. Some practice in programming techniques is recommended.

Technical content of the course

The course will cover:

  • Basic concepts: The role of the shell, advanced input/output redirection.
  • Shell programming: Creating script files, parameters, shell variables, command substitution, "here"-documents, control structures, testing and doing computations, various subjects.
  • The programmable filter sed: General functionality, actions, selections, applications.
  • The programmable filter awk: General functionality, variables, actions, functions, selections, arrays, applications.
  • Various utilities: Data compression, bundling files, executing commands regulary or once in the future.

Not covered in this course

  • Programming with the csh and tcsh shells.
  • Perl and Python programming; using the Perl and/or Python languages could be considered to be "the next step" beyond what this course teaches. However, unlike the shell and awk languages, they are definitely not languages for the novice programmer.


Course attendees receive the following documentation:
  • A student pack with copies of the presentations, lab exercises, and answers to the exercises.
  • A reference card with frequently used options of most Linux/UNIX commands.


Shortly after the course the student will receive a certificate as a proof of participation.
