dcopy(1M)                                               dcopy(1M)



NAME
     dcopy - copies System V File System-style file  systems  for
     optimal access time

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

ARGUMENTS
     -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 the order of directory entries as is.  (The
          default behavior is to move subdirectories to the
          beginning of directories.)

     -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 argument are used.

     inputfs
          Specifies the existing file system.  For best results,
          inputfs should be a raw device.

     outputfs
          Specifies a file system, appropriately sized to hold
          the reorganized result.  For best results, outputfs
          should be a block device.

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

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

DESCRIPTION
     dcopy copies SVFS-style file system inputfs to outputfs.
     You should run the dcopy command only 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 dcopy command catches interrupt and quit signals and
     reports on its progress.  To terminate dcopy, send a quit
