Awk help required
Hi All,

I have 2 .csv files as below

File1.csv
Code:
name1,20,30,date1
name2,30,40,date1

File2.csv
Code:
name1,25,35,date1
name2,45,55,date1

Can any one help me to add the 2nd and 3rd column of file1 and file2 and write the output into a new file as below

Code:
name1,45,65,date1
name2,75,95,date1

Thanks in advance.
Ajay

if you are in Solaris use nawk instead of awk
if you are in Linux use gawk

Excuse me for ask. Why does he must use a recent awk version? I don't see that something is not included in original awk

the one "1" in bold in the code below is not recognized in the old awk versions.

Code:
awk 'BEGIN{FS=OFS=","}NR==FNR{a[$1]=$2;b[$1]=$3;next}NF{$2+=a[$1];$3+=b[$1]}1' file1 file2
