Linux Advanced Shell Programming Tools Course Overview
The Linux Advanced Shell Programming Tools course is designed to give delegates practical experience using a range of Linux tools to manipulate text and incorporate them into Linux shell scripts.
The delegate will learn and acquire skills as follows:
- Backing up and restoring files with tar
- File compression
- Scheduling background jobs with crontab and at
- Comparing file contents
- Splitting files
- Identifying and translating characters
- Review of regular expressions
- Editing text files with sed
- Pattern scanning and report generating with awk
- Debugging awk scripts
- Miscellaneous commands
Who will the Course Benefit?
Programmers, developers and system administrators who need to construct shell scripts using advanced text handling facilities.
The Linux Advanced Shell Programming Tools course assumes knowledge of the Linux Operating System to the level covered in the Linux Introduction course. Some shell programming experience to the level covered in Linux Shell Programming is also necessary.
Course objectives
To provide the knowledge and skills to make effective use of a wide range of standard Linux programming and development tools.
