To Anbu23,

It worked.
Thanks for your reply and my apology for being a dumb.

To mph,
Simple way using awk:
Code:
read x
echo $x | awk '{ printf "%0"length"d\n", ++$0 }'

Cheers,
Tayyab

I need to do an add function but it should include the prefixed zeros

For Example
i=00123
j=`expr $i + 1`

The output it shows is 124 but I want the output to be 00124

Could any one help me finding out how to do this

Thanks
Its easy with Python

Code:
import string
i = "00123"
print string.zfill( int(i) + 1 , len(i) )

Output:
Code:
00124

Sweeeet! I'm all for less code, but my two remaining brain cells are for less thinking. So I'll have to commit this on to my favorite code snippets file. Smilie
