I know that bash supports some kind of list data structure:
list="1 2 3"
for i in $list; do
echo "$i"
done
But what about arrays? Does bash have array data structure? And if so, how it would look like?

Bash supports one dimensional arrays.
Setting:
my_array=(1 2 3)
my_array[0]=0
my_array[2]=2
Retrieving:
echo ${my_array[1]}
2
echo ${my_array[@]} # all values
0 2 2

There's a few different notations for arrays in bash.
You can define an array like name[index]=value, or like name=(val1 val2 val3), or explicitly declare an array using declare -a ARRAYNAME. You can reference individual elements of an array with ${name[index]} or the whole array with ${name[@]}.
