Those are SQL statements. If you wanted to restore a dump, you'd create
a new database then redirect stdin for mysql to the dump file: each of
those statements inserts a record into the database.

Try selecting into a new file in /tmp/ -- that directory should always be
world-writable. If it can't do it you probably still have a GRANT problem.
If you can it's just a file permissions problem. The file is being
written as user/group mysql/mysql, since that's what the server is
running as.

If you have a GRANT problem take a look at /etc/my.cnf to see if there's
anything suspicious there. I don't know what this might be -- don't have
the problem here -- but I have an account with an ISP who disallows
GRANT FILE somehow, so I suspect that there is a configuration way to
do so. (Like I said before, there are security issues with this.)
