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 either 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 pre-
       cise 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 commands that  are  exe-
              cuted.   Specifying  this option more than once inhibits execution of any file sys-
              tem-specific commands.  This is really only useful for testing.

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

       fs-options
              File  system-specific  options  to  be  passed  to  the  real  file system 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.
