| 29 | .Sh DESCRIPTION | |
| 30 | The | |
| 31 | .Nm | |
| 32 | utility uncompresses files compressed by | |
| 33 | .Xr compress 1 | |
| 34 | and recompresses them with | |
| 35 | .Xr gzip 1 . | |
| 36 | .Pp | |
| 37 | The options are as follows: | |
| 38 | .Bl -tag -width Ds | |
| 39 | .It Fl f | |
| 40 | Overwrite existing | |
| 41 | .Sq .gz | |
| 42 | files. | |
| 43 | Unless this option is specified, | |
| 44 | .Nm | |
| 45 | refuses to overwrite existing files. | |
| 46 | .It Fl t | |
| 47 | Test integrity of the gzipped file before deleting the original file. | |
| 48 | If the integrity check fails, the original | |
| 49 | .Sq .Z | |
| 50 | file is not removed. | |
| 51 | .It Fl v | |
| 52 | Print a report specifying the achieved compression ratios. | |
| 53 | .It Fl 9 | |
| 54 | Use the -9 mode of | |
| 55 | .Xr gzip 1 , | |
| 56 | achieving better compression at the cost of slower execution. | |
| 57 | .It Fl K | |
| 58 | Keep the original | |
| 59 | .Sq .Z | |
| 60 | file if it uses less disk blocks than the gzipped one. | |
| 61 | A disk block is 1024 bytes. | |

| 64 | .Xr gzip 1 | |
| 65 | .Sh CAVEATS | |
| 66 | The | |
| 67 | .Nm | |
| 68 | utility tries to maintain the file mode of the original file. | |
| 69 | If the original file is not writable, it is not able to do that and | |
| 70 | .Nm | |
| 71 | will print a warning. |
