NAME
      mkfs (generic) - construct a file system

SYNOPSIS
      mkfs [-F FSType] [-C] [-V] [-m] [current_options] [-o specific_options]
      special       [operands]

DESCRIPTION
      mkfs constructs a file system by writing on the special file; special
      must be the first argument.  The file system is created based on the
      FSType, specific_options and operands specified on the command line. mkfs
      waits 10 seconds before starting to construct the file system.  During
      this time the command can be aborted by entering a delete (DEL).

      operands are FSType-specific and the FSType specific manual page of mkfs
      should be consulted for a detailed description.

      current_options are options supported by the s5-specific module of mkfs.
      Other FSTypes do not necessarily support these options.  specific_options
      indicate suboptions specified in a comma-separated list of suboptions
      and/or keyword-attribute pairs for interpretation by the FSType-specific
      module of the command.

      The options are:

      -F        Specify the FSType to be constructed.  The FSType should either
                be specified here or be determinable from /etc/vfstab by
                matching the special with an entry in the table.

      -C        Create no more than 64K inodes.  Ensures compatibility with
                pre-Release 4 UNIX.  diskadd [see diskadd(1M)] calls mkfs with
                this option.

      -V        Echo the complete command line, but do not execute the command.
                The command line is generated by using the options and
                arguments provided by the user and adding to them information
                derived from /etc/vfstab.  This option should 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. It cannot be used with
                current_options, specific_options, or operands.  It must be
                invoked by itself.

      -o        Specify FSType-specific options.

NOTES
      This command may not be supported for all FSTypes.
