NAME

       mkfs - build a Linux filesystem

SYNOPSIS

       mkfs [options] [-t type] [fs-options] device [size]

DESCRIPTION

       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 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 in a number of directories, like perhaps /sbin, /sbin/fs, /sbin/fs.d, /etc/fs, /etc (the precise list is defined at
       compile time but at least contains /sbin and /sbin/fs), and finally in the directories listed in the PATH environment variable.	Please see
       the filesystem-specific builder manual pages for further details.

OPTIONS

       -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.	Although not guaranteed, the following	options  are  sup-
	      ported 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 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 and exit.

BUGS

       All  generic  options  must precede and not be combined with filesystem-specific options.  Some filesystem-specific programs do not support
       the -V (verbose) option, nor return meaningful exit codes.  Also, some filesystem-specific programs do not automatically detect the  device
       size and require the size parameter to be specified.
