mkfs - build a Linux filesystem
mkfs [options] [-t type] [fs-options] device [size]
This mkfs frontend is deprecated in favour of filesystem specific
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 exit code 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
Produce verbose output, including all filesystem-specific com-
mands that are executed. Specifying this option more than once
inhibits execution of any filesystem-specific commands. This is
really only useful for testing.
Display version information and exit. (Option -V will display
version information only when it is the only parameter, other-
wise it will work as --verbose.)
Display help text and exit.
All generic options must precede and not be combined with filesystem-
specific options. Some filesystem-specific programs do not automati-
cally detect the device size and require the size parameter to be spec-
