mkfs - build a Linux filesystem
[options] [-t type
This mkfs frontend is deprecated in favour of filesystem specific
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.
), 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
- -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
- -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
- -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.
