DCOPY(ADM)                         UNIX System V



     Name
          dcopy - copy UNIX filesystems for optimal access time


     Syntax
          /etc/dcopy [-sX] [-an] [-d] [-v]  [-ffsize[:isize]]  inputfs
          outputfs


     Description
          The dcopy command copies  filesystem  inputfs  to  outputfs.
          Inputfs  is  the  device  file for the existing file system;
          outputfs is the device file to hold the reorganized  result.
          This  utility  is  for  UNIX  fileystems only.  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.

          With no options, dcopy copies files from inputfs compressing
          directories   by   removing   vacant  entries,  and  spacing
          consecutive blocks in a file by the optimal rotational  gap.
          The possible options are:

          -sX       supply device information for creating an  optimal
                    organization  of blocks in a file.  The forms of X
                    are the same as the -s option of fsck(ADM).

          -an       place the files not accessed in n days  after  the
                    free   blocks   of  the  destination  file  system
                    (default for n is 7).  If no n is specified,  then
                    no movement occurs.

          -d        leave order of directory entries as is (default is
                    to   move  sub-directories  to  the  beginning  of
                    directories).

          -v        currently reports how many files  were  processed,
                    and  how  big the source and destination freelists
                    are.

          -ffsize[:isize]
                    specify the outputfs file system  and  inode  list
                    sizes  (in  blocks).  If the option (or :isize) is
                    not given, the values from the inputfs are used.

          dcopy catches interrupts  and  quits,  and  reports  on  its
          progress.   To  terminate dcopy send a quit signal, followed
          by an interrupt or quit.
