Loops and Iteration Lab

In this hands-on lab, you'll master bash loops and iteration patterns essential for automation and batch processing. You'll learn for loops, while loops, until loops, nested loops, and arrays to build production-ready automation tools.

You'll implement server deployment automation, log file processing, configuration validation, backup rotation, and multi-environment deployments. These skills are fundamental to platform engineering and infrastructure automation.

By the end of this lab, you'll understand:

• for loops for iterating over lists, ranges, and command output
• while loops for condition-based iteration
• until loops and loop control (break/continue)
• Nested loops for multi-dimensional processing
• Bash arrays and indexed data structures
• Batch file processing and validation
• Configuration deployment pipelines
• Backup rotation and cleanup strategies
• Real-world automation patterns
