Loop through Elements of Array in Bash

Loop through Elements of Array

To loop through elements of array in Bash, use the expression ${arr[@]} to get all the elements and use For loop to loop through each one of these elements.

Example

In the following script, we take an array arr with three elements and iterate over the elements of this array using For loop.

Example.sh

arr=("apple" "banana" "cherry")

for element in "${arr[@]}";
do
    echo $element
done

Output

apple
banana
cherry
