I have two data files; the first, FileA has fewer lines, the second, FileB has more. FileA [75MB] is a subset of FileB [20GB]. Both files are tab delimited.
What I want to do?
When the first two columns for FileA match the first two columns of FileB, I want to print all 24 columns of FileB.
The output file should have a row number == the number of rows in FileA.
I tired this in AWK:
When I run, it throws the error:
I can't figure out why this won't work. If someone can, I'd appreciate the help a lot !!
