The cmp command compares two files, and (without options)
reports the location of the first
difference between them. It can deal with both binary and
ASCII file comparisons. It does a
byte-by-byte comparison.

But in diff compares two files, directories, etc, and
reports all differences between the two. It
deals only with ASCII files. It’s output format is designed
to report the changes necessary to convert
the first file into the second.
