Top Forums UNIX for Beginners Questions & Answers Data match 2 files based on first 2 columns matching only and join if match Post 303041358 by Chubler_XL on Thursday 21st of November 2019 09:53:25 PM

An example input file and desired output would help avoid some misinterpretation.

I believe this fills your requirement:

Code:
awk 'FNR == NR { h[$1,$2] = $3; next } $1 SUBSEP $2 in h {print h[$1,$2]}' file1 file2

Or, if you know column 3 isn't blank:

Code:
awk 'FNR == NR { h[$1,$2] = $3; next } $0 = h[$1,$2]' file1 file2
