MKFS(8)                      System Administration                     MKFS(8)

NAME
       mkfs - build a Linux filesystem
SYNOPSIS
       mkfs [options] [-t type] [fs-options] device [size]
DESCRIPTION
       mkfs  is  used  to build a Linux filesystem on a device, usually a hard
       disk partition.  The device argument is either the  device  name  (e.g.
       /dev/hda1,  /dev/sdb2),  or  a  regular  file  that  shall  contain the
       filesystem.  The size argument is the number of blocks to be  used  for
       the filesystem.
       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 filesystem
       builders (mkfs.fstype) available under Linux.  The  filesystem-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 filesystem-specific builder manual pages for further details.
OPTIONS
       -t, --type type
              Specify  the  type of filesystem to be built.  If not specified,
              the default filesystem type (currently ext2) is used.
       fs-options
              Filesystem-specific options to be passed to the real  filesystem
              builder.   Although  not  guaranteed,  the following options are
              supported by most filesystem builders.
       -V, --verbose
              Produce verbose output, including all  filesystem-specific  com-
              mands  that are executed.  Specifying this option more than once
              inhibits execution of any filesystem-specific commands.  This is
              really only useful for testing.
       -V, --version
              Display  version  information and exit.  (Option -V will display
              version information only when it is the only  parameter,  other-
              wise it will work as --verbose.)
       -h, --help
              Display help and exit.
BUGS
       All  generic  options must precede and not be combined with filesystem-
       specific options.  Some filesystem-specific programs do not support the
       -V  (verbose)  option,  nor  return  meaningful exit codes.  Also, some
       filesystem-specific programs do not  automatically  detect  the  device
       size and require the size parameter to be specified.

       the ext2 filesystem.
