Loop Through an Array in Bash

We create an index array with the -a option, which is named cities_array. We loop through ${cities_array[@]}, which contains all the values of the array, and we display each value with the printf command.

declare -a cities_array=("New York" "London" "Moscow")

for city in "${cities_array[@]}"
do
    printf "$city\n"
done

Output:

New York
London
Moscow
