Array Basics

Bash arrays store multiple values in a single variable, declared with name=(value1 value2 value3). Individual elements are accessed with ${name[index]}, using zero-based indexing. Arrays are one of the few compound data structures Bash offers natively.

Note: Always quote array expansions, like "${arr[@]}", to keep elements with spaces intact.

Example: Array Basics

bash

#!/bin/bash
fruits=("apple" "banana" "cherry")

echo "First fruit: ${fruits[0]}"
echo "Second fruit: ${fruits[1]}"
