GNU implementation of file "knows" some magic numbers and applies them to give a best guess as to what an unkown file is.Thanks, Andy - yes, it told me what the files were, and its best guess was good. (I should know - I created the files!)But no actual magic numbers. :-(
In Windows world, you have file extensions, no magic....In Mac world, the file/directory entry has, I believe, application identifiers.
In Linux world, it is not worked out by extensions or extra attributes on file/directory inodes, but rather on the content of the file. The "magic" numbers might be similar in way of use as to the IANA ports or services -- that is, the magic numbers are arbitrary. Content is king to evaluate the so called "magic".
