  NAME

    dcopy - Copies file systems for optimal access time

  SYNOPSIS

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

  FLAGS

    -sX               Supply device information for creating an optimal
                      organization of blocks in a file.  The forms of X are
                      the same as the -s flag of fsck.

    -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 size(s)
                      (in blocks).  If this flag (or :isize) is not given, the
                      values from the inputfs are used.

  DESCRIPTION

    The dcopy command copies file system inputfs to outputfs.  The inputfs
    variable is the device file for the existing file system; the outputfs
    variable is the device file to hold the reorganized result.  For the most
    effective optimization inputfs should be the raw device and outputfs
    should be the block device.  Both inputfs and outputfs should be unmounted
    file systems (in the case of the root file system, the copy must be to a
    new pack).

    With no flags, 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 interrupts and quits, and reports on its own
    progress.  To terminate dcopy send a quit signal, followed by an interrupt
    or quit.  The dcopy command also attempts to modify its command line
    arguments so its progress can be monitored with ps.

  NOTES

    The dcopy command does not work with Fast File Systems (FFS).
