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?

Accepted Answer

another seq trick will work:

```
 seq -w 30
```

if you check the man page, you will see the -w option is exactly for your requirement:

```
-w, --equal-width
              equalize width by padding with leading zeroes
```
