IFS=', ' read -a array <<< "$string" /* array is the variable name */
To access an individual element:echo "${array[0]}"
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
The last example is useful because Bash arrays are sparse. In other
words, you can delete an element or add an element and then the indices
are not contiguous.unset "array[1]"
array[42]=Earth
