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  speci-
     fied   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.

FILES
     /etc/vfstab    list of default parameters for each file system
