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 a file system, ap-
          propriately sized to hold the reorganized result.  For best
          results, inputfs should be a raw device and outputfs should
          be a 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 rota-
          tional gap.  The possible options are

          -sX   Supplies device information for creating an optimal
                organization of blocks in a file.  The forms of X are
                the same as the -s flag option of fsck(1M).

          -an   Places the files not accessed in n days behind the
                free blocks of the destination file system.  If -an is
                not specified, the value defaults to 7, that is, no
                movement occurs.

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

          -v    Reports how many files were processed, and how big the
                source and destination free lists are.

          -ffsize[:isize]
                Specifies 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 interrupt and quit signals and reports on its
          progress.  To terminate dcopy, send a quit signal and dcopy
          will no longer catch interrupts or quits.
