[root@Llawyr ~]# mkfs --help
Usage:
mkfs [options] [-t <type>] [fs-options] <device> [<size>]

Options:
-t, --type=<type> filesystem type; when unspecified, ext2 is used
fs-options parameters for the real filesystem builder
<device> path to the device to be used
<size> number of blocks to be used on the device
-V, --verbose explain what is being done;
specifying -V more than once will cause a dry-run
-V, --version display version information and exit;
-V as --version must be the only option
-h, --help display this help text and exit

For more information see mkfs(8).
