.TH ZEROS 1 .SH NAME zeros \- write sequence of bytes .SH SYNOPSIS .B zeros [ .IR -r ] [ .IR -v value ] [ [ .IR blocksize ... [ .IR numblocks ] ] .SH DESCRIPTION .B 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 .I -r option requests that each block be the same, but randomly generated. The .IR -v value option sets the value of each byte (default 0). Typically .IR zeros has a specialised use: ensuring a file has the desired number of blocks in it to hold a file system image, before reaming it. .SH EXAMPLE To create and initialize a file system containing 2048 1024 byte blocks .IP .EX zeros 1024 2048 >kfs.file mount -c {disk/kfs -r kfs.file} /n/local .EE .SH SOURCE .B /appl/cmd/zeros.b .SH SEE ALSO .IR kfs (4)
