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.
