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. -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.
