 NAME    [Toc]    [Back]
      mkfs - construct a file system (generic)

 SYNOPSIS    [Toc]    [Back]
      /usr/sbin/mkfs [-F FStype] [-o specific_options] [-V] special
           [operands]

      /usr/sbin/mkfs [-F FStype] [-m] [-V] special

 DESCRIPTION    [Toc]    [Back]
      The mkfs command creates a file system by writing on the special file
      special.  operands are listed on file system specific manual pages
      (see "SEE ALSO").

    Options    [Toc]    [Back]
      mkfs recognizes the following options:

           -F FStype      Specify the file system type on which to operate
                          (see fstyp(1M) and fs_wrapper(5)).  If this option
                          is not included on the command line, then the file
                          system type is determined from the file /etc/fstab
                          by matching special with an entry in that file.
                          If there is no entry in /etc/fstab, then the file
                          system type is determined from the file
                          /etc/default/fs.

           -m             Display the command line that was used to create
                          the file system.  The file system must already
                          exist.  This option provides a means of
                          determining the parameters used to construct the
                          file system.

           -o specific_options
                          Specify options specific to the file system type.
                          specific_options is a list of suboptions and/or
                          keyword/attribute pairs intended for an FStype-
                          specific module of the command.  See the file
                          system specific manual entries for a description
                          of the specific_options that are supported, if
                          any.

           -V             Echo the completed command line, but perform no
                          other action.  The command line is generated by
                          incorporating the specified options and arguments
                          with other information derived from /etc/fstab.
                          This option allows the user to verify the command
                          line.
