Bash 4+ arrays — declare, access by index, get all elements with [@], length with #. The quoting matters: "${arr[@]}" preserves each element; ${arr[@]} word-splits.
Bash
fruits=("apple" "banana" "cherry")
# Access
echo "${fruits[0]}" # apple
echo "${fruits[2]}" # cherry
# Length
echo "${#fruits[@]}" # 3
# All elements (quoted preserves spaces in each item)
for f in "${fruits[@]}"; do
echo " - $f"
done
# Iterate with index
for i in "${!fruits[@]}"; do
echo "$i: ${fruits[i]}"
done
# Append
fruits+=("date" "elderberry")
echo "${#fruits[@]}" # 5Save your own code snippets
