hello

I need to compare 2 text files. File 1 has 2 columns and file 2 has 1 to many.
Sample:

File 1:

111 555
222 666
333 777
444 755

File 2:

000 110 113 114
844 111 555 999
202 777 865 098 023
222 313 499
065 655 333 011 890 777
433

Results should be from file1:
222 666
444 755

I need to find all the lines from file 1 that the data in column 1 and 2 do not also exist in a row in anywhere in file 2. The files are a few thousand lines each.

I've looked at awk and nawk but to be honest I'm not sure where to begin with this.

Thanks very much
