This command compares the differences between two sorted files in one column and displays the results. If no parameter is specified, the results are divided into three lines: rows 1st are only columns that have appeared in 1st files, and rows 2nd are columns that have only appeared in 2nd files, rows 3rd are columns that appear in files 1st and 2nd. If the given file name is "-", The comm command reads data from the standard input device.Syn
