| 29 | .SH DESCRIPTION |
| 30 | This command is a relative of nullfile. Like nullfile, it can be used |
| 31 | to write all unused disk space with '0', thereby making file systems that |
| 32 | are stored on virtual machines easier to pack. In addition, zerofill can |
| 33 | fill unused disk space with random data before zeroing, which can be useful |
| 34 | to remove forensic trace of deleted files. Finally, zerofile can be told |
| 35 | to operate on and zero (erase) complete disk devices. |
