Hi, normally you should start a new thread for that...
Try:
Code:
sed 's/[^,]$/&,/'file

oops! Am sorry... Thanks man...

Also, it will be of great help if you give me some threads for dealing with comma delimited files. I can go through them to get a better understanding about comma delimited files. I have been searching over here and in google but couldn't find something solid, it looks like am missing something.

bhargav, your code will append , to the last field even if it is already there.
scrutinizer's code works fine. It appends "," only if it is not there.
