mkfs - build a Linux filesystem
mkfs [options] [-t type] [fs-options] device [size]
This mkfs frontend is deprecated in favour of filesystem specific
mkfs.<type> utils.
mkfs is used to build a Linux filesystem on a device, usually a
hard disk partition. The device argument is either the device name
(e.g., /dev/hda1, /dev/sdb2), or a regular file that shall contain
the filesystem. The size argument is the number of blocks to be
used for the filesystem.
The exit status returned by mkfs is 0 on success and 1 on failure.
In actuality, mkfs is simply a front-end for the various
filesystem builders (mkfs.fstype) available under Linux. The
filesystem-specific builder is searched for via your PATH
environment setting only. Please see the filesystem-specific
builder manual pages for further details.
-t, --type type
Specify the type of filesystem to be built. If not specified,
the default filesystem type (currently ext2) is used.
fs-options
Filesystem-specific options to be passed to the real
filesystem builder.
-V, --verbose
Produce verbose output, including all filesystem-specific
commands that are executed. Specifying this option more than
once inhibits execution of any filesystem-specific commands.
This is really only useful for testing.
-h, --help
Display help text and exit.
-V, --version
Display version and exit. (Option -V will display version
information only when it is the only parameter, otherwise it
will work as --verbose.)
All generic options must precede and not be combined with
filesystem-specific options. Some filesystem-specific programs do
not automatically detect the device size and require the size
parameter to be specified.

The manual page was shamelessly adapted from Remy Card’s version
for the ext2 filesystem.
