Indexed Arrays: Creation and Manipulation

Indexed Arrays: Creation and Manipulation

Indexed arrays store sequences of values accessible by integer indices:

# Creation
declare -a servers=("web01" "web02" "db01")

# Appending elements
servers+=("cache01" "cache02")

# Accessing
echo "${servers[0]}"   # web01
echo "${servers[-1]}"  # cache02 (last element)
echo "Count: ${#servers[@]}" # 5
