mawk script to compare 2 files and report where they match
I have two files and would like a report of where they match.

Example of file1:

Code:
1 1 1
2 2 2
13 14 15
4 4 4
15 16 17
100 102 1004
56 57 890

Example of file2:

Code:
2 2 2
16 10 11
45 22 35
13 14 15
1001 1002 3456
100 102 1004
50 51 52

The desired result is:

Code:
13 14 15
100 102 1004

I am looking for the records that are common to each file.

Thanks,
Kenny.

Code:
nawk 'FNR==NR {f1[$0];next} $0 in f1' file1 file2

not sure why '2 2 2' didn't make it in your sample output........
