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.
