Linux 2.6 - man page for mkfs (linux section 8)

MKFS(8) 										  MKFS(8)

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  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  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.

       The manual page was shamelessly adapted from Remy Card's version for the ext2 file system.
