Top Forums Shell Programming and Scripting Matching two fields in two csv files, create new file and append match Post 303023721 by Scott on Friday 21st of September 2018 08:43:34 AM

Having added code tags to the data as well, I see that file1 has a lot of whitespace (spaces and/or tabs) in the fields. If you're using -F to specify a very specific field separator (,), then the whitespace in those fields will become part of the fields themselves, so an exact match with fields in the other file which do not have the exact same whitespace won't work.

Assuming the logic works, a simple option would be to remove any whitespace directly before, or after a comma in file1.

e.g.
Code:
$ sed 's/[[:space:]]*,[[:space:]]*/,/g' file1 > file1.$$ && awk -F, 'FNR==NR{f2[$1]=$2;next} FNR==1{print $0, "VLAN Name";next} {print $0,($5 in f2)?f2[$5]:"NA"}' OFS=, file2 file1.$$ && rm file1.$$
