I have the same problem just like this, problem is there is a first column preceding look below:

Code:
"Number","Name","Description","Occupation","Email"
"1","Walter White","","Chemistry Teacher","w.w@bb.com"
"2","Jessie Pinkman","","Junkie","j.p@bb.com"
"3","Hank Schrader","","DEA Agent","h.s@bb.com"

I want the same results but I am getting this:
Code:
$ awk -F"," 'NR==FNR{a[$1]=$2;next}{$3=a[$1]}1' OFS="," Bad.csv Breaking.csv

Code:
"Number","Name",,"Occupation","Email"
"1","Walter White",,"Chemistry Teacher","w.w@bb.com"
"2","Jessie Pinkman",,"Junkie","j.p@bb.com"
"3","Hank Schrader",,"DEA Agent","h.s@bb.com"

Can it be possible to not include headers too? Smilie
