Function description: compare whether there are differences between the two files.

Grammar: cmp [- clsv] [- I] [--help] [first file] [second file]

Additional note: when the two files compared to each other are exactly the same, the instruction will not display any information. If a difference is found, the default will indicate the character and column number of the first difference. If no file name is specified or given a file name of "-", the cmp instruction reads the data from the standard input device.

Parameters:

-c or-- print-chars displays the corresponding character in addition to the decimal code that indicates the difference.

-I or-- ignore-initial= specify a number.
