dcopy(1M)                        UNIX System V                        dcopy(1M)


NAME
      dcopy (generic) - copy file systems for optimal access time

SYNOPSIS
      dcopy [-F FSType] [-V] [current_options] [-o specific_options] inputfs
      outputfs

DESCRIPTION
      dcopy copies file system inputfs to outputfs.  inputfs is the device file
      for the existing file system; outputfs is the device file to hold the
      reorganized result.  For the most effective optimization inputfs should
      be the raw device and outputfs should be the block device.  Both inputfs
      and outputfs should be unmounted file systems.

      current_options are options supported by the s5-specific module of dcopy.
      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 on which to operate.  The FSType should
                either be specified here or be determinable from /etc/vfstab by
                matching the inputfs (device) with an entry in the table.

      -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.

      -o        Specify FSType-specific options.

NOTE
      This command may not be supported for all FSTypes.
