Looping Constructs (for, while)

Welcome! In this lesson, we'll dive into the world of loops in Bash scripting. Loops are powerful tools that allow your scripts to repeat a set of commands multiple times.

This is essential for automating repetitive tasks, processing lists of data, or performing actions until a certain condition is met. We'll explore two main types: for loops and while loops.

The for loop is perfect for iterating over a fixed list of items. This list can be a series of words, filenames, numbers, or anything you can define.

Its basic syntax is:

• for variable in item1 item2 ...; do
• commands to repeat
• done

Each item in the list will be assigned to variable, and the commands will run for each one.
