cmp
The cmp
command compares two files, and if they differ, tells the
first byte and line number where they differ. Its arguments are as
follows:
cmp options... from-file [to-file] |
The file name `-' is always the standard input. cmp
also
uses the standard input if one file name is omitted.
An exit status of 0 means no differences were found, 1 means some differences were found, and 2 means trouble.

cmp
Below is a summary of all of the options that GNU cmp
accepts.
Most options have two equivalent names, one of which is a single letter
preceded by `-', and the other of which is a long name preceded by
`--'. Multiple single letter options (unless they take an
argument) can be combined into a single command line word: `-cl' is
equivalent to `-c -l'.
