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)  or  the  mount  point  (e.g.   /, /usr, /home) for 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 enviroment 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 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
              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.

       the ext2 file system.
