Hi, I'd like to compute the ratios of two bash arrays. When there are just 2 elements in each array, I simply do the following as it is the quickest to type. r=( $(bc l <<< ${x[0]}/${y[0]}) $(bc l <<< ${x[1]}/${y[1]}) ) When there are more elements, does anybody has a better way to do it?
for n in "address@hidden" doprintf "%s/%s\n" "${x[n]}" "${y[n]}" done  bc l
