Somebody recently posted an /etc/magic file addendum to allow 'file'
to recognize compressed files. That was really SLICK, but it didn't
work on the unix-pc. So, I got to thinking- what could be wrong?? I
finally figured it out- when dealing with 'byte' types, the unix-pc
treats them as signed, and so things get all screwy. In any case,
after a bit of messing around, I got the following working. Just
append it onto /etc/magic, and it should do it for your system too.
If somebody out there has a better one, please email it to me.
Just unshar the file- it should drop into /tmp/magic. Then, use vi to
simply append it to your /etc/magic file.
Have fun!
