I can tell you what I usually do but I bet there are better ways.
for n in $(seq -w 1 9); do echo $n; done
Then seq -w means that if I have some digits with 2 or more positions it
will pad the lower numbers with 0's in front so they are all equal
If you know the exact number of loops you want this way should work.
