Shell Scripting Basics (Bash)

Summary

Automating repetitive command-line tasks by writing Bash scripts — variables, loops, conditionals, and functions — the entry point into DevOps automation before reaching for a full programming language.

• 1Write a simple Bash script that automates a repetitive task (e.g. backing up a folder).
• 2Practice using variables, if/else conditionals, and a for loop in a script.
• 3Learn to make a script executable and run it directly rather than via `bash script.sh`.
