Linux/Unix shell for power users and programmers («USH»)

• Using the diverse possibilities of the Unix shell and toolbox
• Realising new, efficient tools and small to medium-sized applications independently
• Using shell correctly
• Knowing secure, stable tools/scripts
• Handling errors correctly

In the available basic courses, the amount of content does not allow you to practice all topics in depth in order to expand your knowledge of the shell and its toolbox. This seminar offers the opportunity to do so. You will work with the modern and widespread Korn shell (ksh) or the standard Linux shell, the Bourne Again Shell (bash).

• The first and second days of the course are used to discuss the important programming features of the Bash shell. Subjects will be repeated and combined with new elements of shell programming. The new elements are practiced in small code snippets.
• The third course day is planned as a programming workshop: You will have the opportunity to write tools and scripts which have arisen from the problems of your everyday life with Linux/Unix.

Topics:

• BASH and POSIX standards
• Shell variables 
• Shell syntax 
• Subroutines 
• Include
• Shell pattern 
• Regular expressions with shell 
• Error handling in shell 
• Programming your own tools with shell
