Shell scripting in Linux & UNIX
Learn to read, write and adapt shell scripts during this 3-day ABIS course.
Linux and UNIX users know the shell as the interactive command interpreter. But did you know that the shell is also a real programming language? An experienced shell programmer can write his own commands, and use them to automate a number of frequently recurring tasks.
This course therefore discusses the programming syntax of the shell (in particular of the Bourne shell, and of bash, ksh and zsh). Furthermore, the use of awk and sed is also discussed in detail.
After completion, participants will be able
- to write relatively complex shell scripts themselves,
- understand existing scripts,
- adapt scripts to their needs.

Intended for
Power-users and system administrators of Linux or UNIX who are responsible for the organisation and the management of an efficient UNIX or Linux environment based on intelligent procedures, or who want to automate their daily routine activities.
Background
The participant has followed the Linux / UNIX fundamentals course or has equivalent experience with the system, and has basic knowledge of a programming language.
You can test for yourself to see if you have enough background by filling out the on-line self-test.
Main topics
- Basic shell scripting: a recap
- Working towards batch procedures:
Manipulating text in batch (sed, tr, ...) • unix tools in batch (arithmetic, text manipulation, "here documents", ...) • process synchronisation (wait, trap, exit, return, ...) • functions (definition, function library, function availability)
- Advanced Shell programming - based on the Korn shell, on bash (Linux), and on zsh (macOS):
Writing logical tests • evaluating tests • branching • iterations • arithmetic expressions • interactive scripting
- AWK programming
AWK program structure • verbs • arguments • syntax of an instruction • conditions based on file parsing • regular expressions • search and update of file databases • simple reports
Training method
Classroom instruction based on a handout, presentation and demo's.
A substantial amount of time is spent on individual practice (exercises) and practical use cases.
Certificate
At the end of the session, the participant receives a "Certificate of Completion".
If your aim is to obtain a Linux certificate from LPI, we refer to our LPIC-1 certification track (exam 101).
Duration
3 days.
Course leader
Peter Vanroose (ABIS), Kris Van Thillo (ABIS).
