dcopy(1M)                                               dcopy(1M)



     NAME
          dcopy - copy file systems for optimal access time

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

     DESCRIPTION
          dcopy copies file system inputfs to outputfs.  inputfs is
          the existing file system; outputfs is an appropriately sized
          file system, to hold the reorganized result.  For best
          results inputfs should be the raw device and outputfs should
          be the block device.  dcopy should be run on unmounted file
          systems (in the case of the root file system, copy to a new
          pack).  With no arguments, 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(1M).

          -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 and dcopy
          will no longer catch interrupts or quits.
