MIME Magic

[Samuel]

Hi,

How can I determine the type of a file from "magic bytes", similar to
what the "file" command on unix does? I found

http://docs.python.org/lib/module-mimetypes.html

but this only seems to use the filename (extension) for finding the
type. Any hints?

I'd start by taking a look at "file"'s code. :-)

The thing is being able to identify the signatures of several different types
of files. Here's some help for you:

And here's an example of an authoritative source for that table:

Actually, I am looking for an existing solution because I do not want
to write it from scratch... I hope I am not out of options.

python-magic : Python binding for the magic library

This Python library can be use to query /etc/magic information for a
