You could also try:

nl -ba -s "" -nrz file.dat

if you want something other than 6 digit line numbers, you can also add a -w option with an option argument specifying the number of digits you want.

Thanks Rudic. This was the first time I post query on this forum. Could you please tell me how I can use code tags and what I need to do for that?

Thanks!

You sorted using key from field 17 to field 27, which do not exist. Use field 1, char 17 - char 27 instead: sort -k1.17,1.27 .
BTW, no need to use numeric sort in this case!

Awesome. It worked. Thanks alot.
