DCOPY(1M) INTERACTIVE UNIX System DCOPY(1M)
NAME
dcopy - copy file systems for optimal access time
SYNOPSIS
/etc/dcopy [-sX] [-an] [-d] [-v] [-ffsize[:isize]] inputfs
outputfs
DESCRIPTION
The dcopy command 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.
With no options, dcopy copies files from inputfs compressing
directories by removing vacant entries, and spacing consecu-
tive 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 direc-
tories).
-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 pro-
gress. To terminate dcopy send a quit signal, followed by
an interrupt or quit.
