comm(1) |

comm − select or reject lines common to two sorted files
comm [ − [ 123 ] ] file1 file2
Comm reads file1 and file2, which should be ordered in ASCII collating sequence, and produces a three column output: lines only in file1; lines only in file2; and lines in both files. The filename ’−’ means the standard input.
Flags 1, 2, or 3 suppress printing of the corresponding column. Thus comm −12 prints only the lines common to the two files; comm −23 prints only lines in the first file but not in the second; comm −123 is a no-op.
