Shell loops using non-integers?

Question

I wrote a .sh file to compile and run a few programs for a homework assignment. I have a \"for\" loop in the script, but it won\'t work unless I use only integers:

Answer 1

you can use awk to generate your decimals eg steps of0.1

num=$(awk 'BEGIN{for(i=1;i<=10;i+=0.1)print i}')
for n in $num
do
  ./hw3_2_2 $n
done

or you can do it entirely in awk

awk 'BEGIN{cmd="hw3_2_2";for(i=1;i<=10;i+=0.1){c=cmd" "i;system(cmd) } }'
