What is Loops?

Shell loops automate repetitive tasks with three types: for (iterates over lists), while (executes while condition true), until (runs until condition true). Example: for i in 1 2 3; do echo "$i"; done outputs each number. Essential for script efficiency, automation, and effective Linux shell programming.
