How to add a new line to a bash array?

[I am a nobody]

How can I add a new line to following bash array? The get_group is a function, it assigns a list of members in a group to the GROUP, but the statement GroupList+=${GROUP} stacks the end of the first group and the start of the second group in one line, I tried to add new line to the array, that does not work at all

declare -a GroupList=()
for i in $(seq 1 3); do
GROUP=$(get_group ${i})
GroupList+=${GROUP}
GroupList+="\n" # does not work
done

afaiu, you don't really need the actual newline, but need to make sure that each

Code: Select all

GroupList+=${GROUP}

adds one more member to the array, yes?

i have never tried the '+=' syntax on arrays;
you can see if it worked like this:

Code: Select all

for (( i=0;i<${#GroupList[@]};i++ )); do
    echo "GroupList[$i]: ${GroupList[i]}"
done
