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 device file for the existing file system; outputfs 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 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(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, followed
by an interrupt or quit.
