Bash Script Fundamentals Lab

🛠 Lab from the Platform Engineering Bootcamp. Used in Week 5. Bootcamp landing page: https://academy.tekanaid.com/bootcamps/platform-engineering-bootcamp Parent course(s):

• Week 5: Bash Scripting & Automation (slug: bash-scripting-automation)

🟡 Beta bootcamp lab. Hands-on instructions, check scripts, and solve scripts are in place. Lab is part of the running TaskFlow project that grows across all 21 weeks of the bootcamp.

In this hands-on lab, you'll learn bash scripting fundamentals by building 5 real-world utility scripts that platform engineers use daily. You'll master variables, input/output, command substitution, and basic script structure.

You'll write scripts for file backup, log rotation, system information gathering, disk space monitoring, and automated cleanup. Each script teaches essential bash concepts while solving actual problems you'll encounter as a platform engineer.

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

• Bash script structure (shebang, comments, execution)
• Variables and command substitution ($(), ${})
• User input with read command
• echo and printf for output
• Basic file operations in bash
• Script execution permissions (chmod +x)
• exit codes and return values
• Practical scripting patterns
