zerofill(1) GNU Telephony zerofill(1)

zerofill - clear unused disk space and blank devices.

zerofill [options] [devices] ...

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

--random=count
Number of passes to use writing random data before wiping data.
--help
Outputs help screen for the user.
