mkfs - build a Linux filesystem
type fs-options] device [size]
is used to build a Linux filesystem on a device, usually
a hard disk partition. The
argument is either the device name (e.g.
or a regular file that shall contain the filesystem. The
argument is the number of blocks to be used for the filesystem.
The exit code returned by
is 0 on success and 1 on failure.
is simply a front-end for the various filesystem builders
available under Linux.
The filesystem-specific builder is searched for in a number
of directories, like perhaps
(the precise list is defined at compile time but at least
and finally in the directories
listed in the PATH environment variable.
Please see the filesystem-specific builder manual pages for
- -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.
Although not guaranteed, the following options are supported
by most filesystem builders.
- -V, --verbose
Produce verbose output, including all filesystem-specific commands
that are executed.
Specifying this option more than once inhibits execution of any
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 and exit.
All generic options must precede and not be combined with
Some filesystem-specific programs do not support the
(verbose) option, nor return meaningful exit codes.
Also, some filesystem-specific programs do not automatically
detect the device size and require the
parameter to be specified.
