       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

       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.

              Filesystem-specific options to be passed to the real filesystem

       -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.

       -V, --version
              Display version information and exit.  (Option -V will display
              version information only when it is the only parameter, otherwise
              it will work as --verbose.)

       -h, --help
              Display help text and exit.

       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.

       ext2 filesystem.
