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
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.
