NAME

     newfs_v7fs -- construct a new 7th Edition(V7) File System


SYNOPSIS

     newfs_v7fs [-FZ] [-B byte-order] [-n inodes] [-s sectors] [-V verbose]
                special


DESCRIPTION

     newfs_v7fs builds a 7th Edition(V7) file system on the specified special.
     If it is a device, the size information will be taken from the disk label
     and before running newfs_v7fs the disk must be labeled using
     disklabel(8); the proper fstype is ``Version 7''.  Otherwise, the size
     must be specified on the command line.  V7 filesystem's block size and
     sector size are 512 byte.  Disk address limits are 24 bit.

     The following arguments are supported:

     -B byte-order    Specify the metadata byte order of the file system to be
                      created.  Valid byte orders are `be', `le', and `pdp'.
                      If no byte order is specified, the file system is cre-
                      ated in host byte order.

     -F               Create file system to a regular file (needs the -s
                      option).

     -n inodes        This specifies the number of inodes for the filesystem.
                      If the number of inodes exceeds 65536, it is reduced to
                      65536.

     -s sectors       Create file system with specified number of disk sec-
                      tors.

     -V verbose       This controls the amount of information written to std-
                      out:
                            0    No output.
                            1    Overall size, ilist size, endian and filename
                                 length.
                            2    A progress bar.
                            3
                            4    More verbose message.
                      The default is 3.

     -Z               Fill file with zeroes instead of creating a sparse file.
