Hi all,
How do I select elements with indices that are multiples of 3, in anarray? For example, I have,
list=( 123 native Terminal 456 native Excel 789 native X11 )

and would like to select,

Terminal Excel X11


for i in {1..3}; do
print $list[$(($i*3))]
done

or build a new array:

new=()
for i in {1..3}; do
new+=( $list[$(($i*3))] )
done
