(moved from hard_link_cluster()) that checks the inode/dev of an existing file and either does nothing (when properly linked), or removes the existing file before calling hard_link_one(). - Changed hard_link_check() so that it checks if the master item is marked with FINISHED_LINK (in its hlindex int), and if so, it finishes the current file by calling maybe_hard_link() (and marking it as finished too). Otherwise it marks the item as skipped by setting hlindex to SKIPPED_LINK. - Fixed the outputting of an error in hard_link_one() so that the message is always output when the caller did not request "terse" processing. - Changed hard_link_cluster() so that it marks the master item with FINISHED_LINK and then links only the skipped items (marking them with FINISHED_LINK too).
WHAT IS RSYNC? -------------- rsync is a replacement for scp/rcp that has many more features. rsync uses the "rsync algorithm" which provides a very fast method for bringing remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand. At first glance this may seem impossible because the calculation of diffs between two files normally requires local access to both files. A technical report describing the rsync algorithm is included with this package. USAGE ----- Basically you use rsync just like rcp, but rsync has many additional options. To get a complete list of supported options type rsync --help and see the manual for more information. SETUP ----- Rsync normally uses ssh or rsh for communication. It does not need to be setuid and requires no special privileges for installation. You must, however, have a working ssh or rsh system. Using ssh is recommended for its security features. Alternatively, rsync can run in `daemon' mode, listening on a socket. This is generally used for public file distribution, although authentication and access control are available. To install rsync, first run the "configure" script. This will create a Makefile and config.h appropriate for your system. Then type "make". Note that on some systems you will have to force configure not to use gcc because gcc may not support some features (such as 64 bit file offsets) that your system may support. Set the environment variable CC to the name of your native compiler before running configure in this case. Once built put a copy of rsync in your search path on the local and remote systems (or use "make install"). That's it! RSYNC SERVERS ------------- rsync can also talk to "rsync servers" which can provide anonymous or authenticated rsync. See the rsyncd.conf(5) man page for details on how to setup a rsync server. See the rsync(1) man page for info on how to connect to a rsync server. MAILING LIST ------------ There is a mailing list for the discussion of rsync and its applications. It is open to anyone to join. I will announce new versions on this list. To join the mailing list see the web page at http://lists.samba.org/ To send mail to everyone on the list send it to rsync@samba.org BUG REPORTS ----------- If you have web access then please look at http://rsync.samba.org/ That page contains links to the current bug list, and information on how to report a bug well. You might also like to try searching the internet for the error message you've received, or looking in the mailing list archives at http://mail-archive.com/rsync@lists.samba.org/ To send a bug report, follow the instructions on the bug-tracking page of the web site. CVS TREE -------- If you want to get the very latest version of rsync direct from the source code repository then you can use anonymous cvs. You will need a recent version of cvs then use the following commands: cvs -d :pserver:cvs@pserver.samba.org:/cvsroot login Password: cvs cvs -d :pserver:cvs@pserver.samba.org:/cvsroot co rsync Look at the cvs documentation for more details.
