       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.

           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.

       -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.

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