Unix Manual Pages

DESCRIPTION

is a simple utility to save hard disk space.

This goal is performed by perforate each FILE specified. 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.

EXAMPLES

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

zum file1 file2 filen

zum /pathname/
