NAME
       mkfs - build a Linux file system

SYNOPSIS
       mkfs [ -V ] [ -t fstype ] [ fs-options ] filesys [ blocks ]

DESCRIPTION
       mkfs  is	 used to build a Linux file system on a device, usually a hard
       disk  partition.	  filesys  is  the  device  name   (e.g.    /dev/hda1,
       /dev/sdb2).   blocks  is	 the  number of blocks to be used for the file
       system.

       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  file	system
       builders (mkfs.fstype) available under Linux.  The file system-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 file system-specific builder manual pages for further details.

OPTIONS
       -V     Produce verbose output, including all file system-specific  com-
	      mands  that are executed.	 Specifying this option more than once
	      inhibits execution of any file system-specific  commands.	  This
	      is really only useful for testing.

       -t fstype
	      Specifies	 the  type  of file system to be built.	 If not speci-
	      fied, the default file system type (currently ext2) is used.

       fs-options
	      File system-specific options to be passed to the real file  sys-
	      tem builder.  Although not guaranteed, the following options are
	      supported by most file system builders.

       -c     Check the device for bad blocks before building the file system.

       -l filename
	      Read the bad blocks list from filename

       -v     Produce verbose output.

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

       the ext2 file system.
