dcopy(1M)                      UNIX System V(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.

FILES
      /etc/mnttab list of file systems currently mounted
