.SH NAME
mkfs \- build a Linux filesystem
2006-12-06 17:25:32 -06:00
.SH SYNOPSIS
2006-12-06 17:25:33 -06:00
.B mkfs
[options]
.RB [ \-t
.IR type "] [" fs-options ] " device " [ size ]
2006-12-06 17:25:32 -06:00
.SH DESCRIPTION
.B This mkfs frontend is deprecated in favour of filesystem specific mkfs.<type> utils.
.PP
2006-12-06 17:25:33 -06:00
.B mkfs
is used to build a Linux filesystem on a device, usually
a hard disk partition. The
.I device
argument is either the device name (e.g.,
2006-12-06 17:25:39 -06:00
.IR /dev/hda1 ,
.IR /dev/sdb2 ),
or a regular file that shall contain the filesystem. The
.I size
argument is the number of blocks to be used for the filesystem.

.PP
The exit status returned by
2006-12-06 17:25:33 -06:00
.B mkfs
is 0 on success and 1 on failure.

.PP
In actuality,
2006-12-06 17:25:33 -06:00
.B mkfs
is simply a front-end for the various filesystem builders
(\fBmkfs.\fIfstype\fR)
2006-12-06 17:25:32 -06:00
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
2006-12-06 17:25:32 -06:00
further details.
.SH OPTIONS
.TP
.BR \-t , " \-\-type " \fItype\fR
Specify the \fItype\fR of filesystem to be built.
If not specified, the default filesystem type
2006-12-06 17:25:37 -06:00
(currently ext2) is used.
2006-12-06 17:25:32 -06:00
.TP
.I fs-options
Filesystem-specific options to be passed to the real filesystem builder.
2006-12-06 17:25:32 -06:00
.TP
.BR \-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.
2006-12-06 17:25:32 -06:00
.TP
.BR \-V , " \-\-version"
Display version information and exit. (Option \fB\-V\fR will display
version information only when it is the only parameter, otherwise it
will work as \fB\-\-verbose\fR.)
2006-12-06 17:25:32 -06:00
.TP
.BR \-h , " \-\-help"
Display help text and exit.
2006-12-06 17:25:32 -06:00
.SH BUGS
All generic options must precede and not be combined with
filesystem-specific options.
Some filesystem-specific programs do not automatically
2006-12-06 17:25:33 -06:00
detect the device size and require the
.I size
2006-12-06 17:25:33 -06:00
parameter to be specified.

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