If no parameters are given, the results are displayed in 3 lines: the first line contains only the columns that appear in the first file, the second line contains only the columns that appear in the second file, and the third line contains the columns that appear in both the first and second files. If the file name given is "-", the comm command will read data from the standard input device.

Linux csplit command
