About the array in bash shell script -

just simple question.

i have array:

array=("1 2 3" "4 5 6") 

if do:

echo ${array[0]} echo ${array[1]} 

1 2 3 or 4 5 6 shown.

however, if do:

for iter in ${array[@]} echo $iter done 

the shown value not expected.... can give me right way use it?

quotation need:

for iter in "${array[@]}";    echo "$iter" done
