NAME

zum - free disk space by making holes in files

SYNOPSIS

zum [ FILE ]...

DESCRIPTION

zum reads a files list on the command line and attempts to perforate these files. Perforation means, that series of ‘0’ bytes are replaced by lseek (2)s, thus giving the file system a chance of not allocating real disk space for those bytes.

EXAMPLE

find . -type f -print0 | xargs -0 zum

If you zum under /boot, where your kernel image lives, your system will become unbootable unless you run lilo again.
