What you'll learn-and how you can apply it
- Learn how to write your first hello world shell script
- See how to work with variables
- Use positional parameters
- Apply pattern matching substitution
- Explore looping structures in shell scripts
This training course is for you because...
- This Training provides candidate with the basic skills that are required for working with Bash shell scripts
- Basic knowledge or experience with Linux is recommended
To follow along with the hands-on parts of this course, you are invited to create a new (virtual) machine before the start of the course. Build it according to the following specifications: 1 virtual machine with any Linux distribution, hardware specs are not important.
A basic understanding of Linux will help participants. This knowledge can be found in "Beginning Linux System Administration" (video)
