now first field say 4093 needs to incremented with command line val variable say val is 3 then first field should be 4096.

and all other fields should remain same.

want to know how we can achive this with awk ?

Thanks in advance.

If you just want to add some values to column#1 and leave the remaining as is..then..

awk -F, '{$1=$1+3}1' OFS="," inputfile
