Linux Bash Shell Programming

The Linux Bash Shell Programming course is designed to give delegates practical experience in developing and writing Bash shell scripts. Most of the built-in shell commands are introduced together with the main program control structures.
The course also gives practical experience using a range of Linux tools to manipulate text and incorporate into Linux Bash shell scripts.

Who will the Course Benefit?
Programmers, developers and system administrators who need to construct shell scripts using advanced text handling facilities.

The Linux Bash Shell Programming course assumes knowledge of the Linux Operating System to the level covered in the Linux Introduction Course. Some programming experience may also prove advantageous.
