dcopy(1M)                          (s5)                           dcopy(1M)


   NAME
         dcopy (s5) - copy s5 file systems for optimal access time

   SYNOPSIS
         dcopy [-F s5] [generic_options] [-sX] [-an] [-d] [-v]
         [-ffsize[:isize]] inputfs outputfs

   DESCRIPTION
         generic_options are options supported by the generic dcopy command.

         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 options are:

         -F s5     Specifies the s5-FSType.  Need not be supplied if the
                   information may be obtained from /etc/vfstab by matching
                   the inputfs device with an entry in the file.

         -sX       Supply device information for creating an optimal
                   organization of blocks in a file.  X must be of the form
                   cylinder size:gap size.

         -an       Place the files not accessed in n days after the free
                   blocks of the destination file system If no n is specified
                   then no movement occurs.

         -d        Leave order of directory entries as is.  The default is to
                   move sub-directories to the beginning of directories.

         -v        Reports how many files were processed and how big the
                   source and destination freelists are.

         -f fsize[:isize]
                   Specify the outputfs file system (fsize) and inode list
                   (isize) sizes in logical blocks.  If the suboption (or
                   :isize) is not given, the values from 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.

   NOTES
         fsck should be run on the new file system created by dcopy before it
         is mounted.
