48If the integrity check fails, the original
49.Sq .Z
50file is not removed.
51.It Fl v
52Print a report specifying the achieved compression ratios.
53.It Fl 9
54Use the -9 mode of
55.Xr gzip 1 ,
56achieving better compression at the cost of slower execution.
57.It Fl K
58Keep the original
59.Sq .Z
60file if it uses less disk blocks than the gzipped one.
61A disk block is 1024 bytes.
