rsync-2.5.6: description + notes

rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speedup file transfers when the destination file already exists. The rsync home page has more information.

The rsync remote-update protocol lets rsync transfer just the differences between two sets of files across the network link, using an efficient checksum-search algorithm described in the technical report that accompanies this package.

Some of the additional features of rsync are:

Note: this is not the same program as /usr/sbin/rsync. An error message like:

    rsync: ERROR: Illegal option -- -
    usage: rsync _c_command _r_rcsdir _Rv dirname_...
    EOF in read_timeout
usually means that the wrong rsync was found on the remote machine, either because the freeware rsync wasn't installed, or because of PATH problems (see the --rsync-path option). This build uses --rsync-path=/usr/freeware/bin/rsync by default.
