       mkfs - build a Linux file system


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


       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),  or  a  regular  file  that  shall contain the file system.
       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.


       -V     Produce  verbose  output,  including  all  file  system-specific
              commands  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
              specified, the default file  system  type  (currently  ext2)  is

              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.


       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.
