Hi All!!

So, my OUTPUT would be as under :

222222222
222222222
222222222
222222222

and so on.....

Please Help with Backup Shell Script. Thanks in advance

I've move this thread from "How to Post in the The UNIX and Linux Forums". Please stop posting technical questions in that forum.

Please post what you've tried so far, in code tags.

As much as I'd like to believe you, that'd be difficult looking at your below quote. The problem is similar, and the sample data are identical.

Please explain in detail why and how this is NOT homework, like the company you work for, the project your work on, and / or the problem background or reasoning behind. Seriously, persuade us, don't try kidding us!

Hi pavand...

Before asking for help get you output requirements correct first.

You OUTPUT shows 4 lines of 9 characters, (ALL identical?), instead of 8 lines of 8 characters, (ALL identical?).

How can we possibly know which line of the first 8 OR 9 characters are needed when they all identical, or am I missing something?
