Note:

It is best to use a subscript separator and not just glue the index fields together to avoid possible index creep:

For example, suppose that you have the fields A1 and 1 and also the the fields A and 11. They would both produce the index "A11", which would corrupt the results.

With the standard awk SUBSEP subscript separator , (character 034 by default) this can be avoided:
Code:
awk 'NR==FNR{A[$1,$2]; next} !(($1,$2) in A)' file2 file1
