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) |
