5/3     Is it possible to bzip2 on the fly? Like:
        % dump_stuff | bzip2 -stdin > dump_file.bz2
        \_ Yup, it works fine.  You don't even need a flag:
           % dump_stuff | bzip2 > dump_file.bz2
           \_ whoa, why didn't anyone tell me about this, and why is this
              not on the man page. I've been doing the stupid command
              for years:
                % mysqldump > f.sql; bzip2 f.sql
                \_ "If no file names are specified, bzip2 compresses
                    from standard input to standard output."
