It's not a text file, right? So "tail -1" is a bit dubious, as POSIX
1003.1-2004 <http://www.opengroup.org/susv3/utilities/tail.html> says
that the input to "tail" must be a text file unless -c is specified.
Also, this is more controversial, but POSIX says portable scripts are
supposed to use "tail -n 1" rather than "tail -1". There are a few
implementations that don't support the obsolete "tail -1" form.
