NAME
      mkfs - construct a file system
 


SYNOPSIS
      mkfs [  -F FSType  ]   [  generic_options  ]   [  -o FSType-
      specific_options ]  raw_device_file  [ operands ]
 


DESCRIPTION
      The  mkfs  utility  constructs  a   file   system   on   the
      raw_device_file  by  calling  the specific mkfs module indi-
      cated by  -F FSType.
 
      Note:  ufs  file  systems  are  normally  created  with  the
      newfs(1M) command.
 
      generic_options  are  independent  of  file   system   type.
      FSType-specific_options   is   a  comma-separated   list  of
      keyword=value pairs (with no intervening spaces), which  are
      FSType-specific.  raw_device_file  specifies the disk parti-
      tion on which to write the file system. It is  required  and
      must  be  the first argument following the  specific_options
      (if any). operands are  FSType-specific.   See  the  FSType-
      specific  manual page of  mkfs (for example,  mkfs_ufs (1M))
      for a detailed description.
 


OPTIONS
      The following are the generic options for mkfs:
 
      -F    Specify the  FSType to be constructed. If  -F  is  not
            specified, the  FSType is determined from  /etc/vfstab"
            by matching the  raw_device_file with a  vfstab entry,
            or by consulting the  /etc/default/fs file.
 
      -V    Echo the complete command line, but do not execute the
            command.  The  command  line is generated by using the
            options and arguments  provided  and  adding  to  them
            information     derived     from     /etc/vfstab    or
            /etc/default/fs. This option may be used to verify and
            validate the command line.
 
      -m    Return the command line which was used to  create  the
            file  system. The file system must already exist. This
            option provides a means  of  determining  the  command
            used in constructing the file system.
 
      -o    Specify  FSType-specific options. See the manual  page
            for the  mkfs module specific to the file system type.
 
 USAGE
      See largefile(5) for the description of the behavior of mkfs
      when encountering files greater than or equal to 2 Gbyte ( 2
     **31 bytes).
