Tags: [bash][array]

Initiate an array 🔗

myArray=( element_1 element_2 element_n )
myArray2=(
    element_1
    element_2
    element_n
)

Access item by index 🔗

echo ${myArray[2]}

Iterate through array 🔗

To iterate over the elements:

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

To get both the index and the value:

for index in "${!array[@]}"
do
    echo "$index ${array[index]}"
done

Append element to array 🔗

myarray=()
myarray+=('foo')
myarray+=('bar')
