ZEROS(1) ZEROS(1)
NAME
zeros - write sequence of bytes
SYNOPSIS
zeros [ -r ] [ -vvalue ] [ [ blocksize... [ numblocks ] ]
DESCRIPTION
Zeros writes a sequence of bytes to standard output. The
arguments specify the nature of the bytes, block size in
bytes, and the number of blocks to output. The -r option
requests that each block be the same, but randomly gener-
ated. The -vvalue option sets the value of each byte
(default 0). Typically zeros has a specialised use: ensur-
ing a file has the desired number of blocks in it to hold a
file system image, before reaming it.
EXAMPLE
To create and initialize a file system containing 2048 1024
byte blocks
zeros 1024 2048 >kfs.file
mount -c {disk/kfs -r kfs.file} /n/local
