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 work through the labs in this course participants need to install and configure their own lab environment. This can be a Linux virtual machine that runs in virtualization software on the participant's own computer, using software like VMware Workstation or Oracle VirtualBox, or on a dedicated computer.
Instructions on how to set up a lab environment: Preparing an Environment for Doing Labs
A basic understanding of Linux will help participants. This knowledge can be found in "Beginning Linux System Administration" (video)
