dcopy(ADM)                      19 June 1992                      dcopy(ADM)


 Name

    dcopy - copy UNIX filesystems for optimal access time

 Syntax

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

 Description

    The dcopy command copies filesystem inputfs to outputfs.  inputfs is the
    device file for the existing file system; outputfs is the device file to
    hold the reorganized result.  This utility is for UNIX fileystems only.
    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.

    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 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(ADM).

    -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 ter-
    minate dcopy send a quit signal, followed by an interrupt or quit.

    dcopy also attempts to modify its command line arguments so its progress
    can be monitored with ps(C).
