Thank you for the quick reply. I apologize if this is a novice question, but so I'm clear, I would run it like this?
file1=master.txt
file2=ref.txt
awk 'FILENAME=="ref.txt"{A[$2]=$1}
FILENAME=="master.txt"{if(A[$1]){print A[$1]}else{print $0}}' ref.txt master.txt
When I try that, I have no output - I'm sure I'm not using it correctly.
Thanks

Trying to use awk to:
update $2 in file2 with the $2 value in file1, if $1 in file1 matches $13 in file2, which is tab-delimeted. The $2values may already be the same so in that case nothing happens and the next line is processed.
There are exactly 4,605 unique $13 values. Thank you :).
