extract all rows from file_1 except those with first two columns matching the first two columns from file_2
Clash Royale CLAN TAG#URR8PPP
I would like to do the inverse of this (exactly same example):
Extract rows from file_1 based on matching the first two columns from a file_2
That is, extract all rows from file_1 except those with the first two columns matching the first two columns from file_2.
Answer:
awk 'NR==FNR get[$1" "$2]++; next !get[$1" "$2]' f2.txt f1.txt
text-processing awk sed

You can use the logical negation of the previous condition:!($1" "$2 in a)
