COMM(1) USER COMMANDS COMM(1) NAME comm - display lines in common, and lines not in common, between two sorted lists SYNOPSIS comm [ -1| -2| -3| -12| -13| -23 ] filename1 filename2 DESCRIPTION comm reads filename1 and filename2, which should be ordered in ASCII collating sequence (see sort(1V)), and produces three-column output when no options are specified: o Column 1 contains lines that occur only in filename1. o Column 2 contains lines only in filename2. o Column 3 contains lines common to both files. The filename `-' means the standard input. OPTIONS The following options can be used to suppress the indicated columns from display. You can specify `-123', but doing so suppresses all output. -1 Suppress column 1; omit lines only in filename1. -2 Suppress column 2; omit lines only in filename2. -3 Suppress column 3; omit lines common to both files. -12 Suppress columns 1 and 2; only show lines common to both files. -13 Suppress columns 1 and 3; only show lines in filename2. -23 Suppress columns 2 and 3; only show lines in filename1. SEE ALSO cmp(1), diff(1), sort(1V), uniq(1) BUGS The options suppress, rather than select the columns you indicate. Sun Release 4.1 Last change: 9 September 1987
