The file command is a file format identification utility that has been a part of Unix distributions for many years.
The Debian manpage gives an overview of its functionality.
The program source includes a database of heuristics for determining file types, which includes a variety of 'magic numbers' which characterise files. This database is not portable, but is potentially adaptable.
