Range with leading zero in bash

Question

How to add leading zero to bash range?
For example, I need cycle 01,02,03,..,29,30
How can I implement this using bash?

Answer 1

A "pure bash" way would be something like this:

echo {0..2}{0..9}

This will give you the following:

00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

Removing the first 00 and adding the last 30 is not too hard!
