mkfs

MKFS(8) 						      System Manager's Manual							   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-spe-
       cific  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	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  sup-
	      ported 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.
