Another way with always awk :
Code:
echo '079661/3' | awk -F'/' '{fmt = "%0" length($1) "d\n" ;for (i=0; i<$2; i++) printf(fmt, $1+i)}'

Difference between above codes

@vgersh99:

Can you tell me in what way the 2 codes are different, because they give the same result otherwise ??

Also since I have to use this code on a particular field of a csv(3rd field), where some of the records might not have a '0' in the beginning. Ex: 976651/4

Is this code generic and work for even those entries??

use the 3-rd post of mine - it handles the NON-zero leading numbers like '10079661/3'. Or use aigles' solution - they're very similar.
