See the GNU General Public Licence for details. rsync is a file transfer program capable of efficient remote update via a fast differencing algorithm. Usage: rsync [OPTION]... SRC [SRC]... DEST or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST or rsync [OPTION]... [USER@]HOST:SRC [DEST] or rsync [OPTION]... [USER@]HOST::SRC [DEST] or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST] The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect to an rsync daemon, and require SRC or DEST to start with a module name. Options -v, --verbose increase verbosity -q, --quiet suppress non-error messages --no-motd suppress daemon-mode MOTD (see manpage caveat) -c, --checksum skip based on checksum, not mod-time & size -a, --archive archive mode;

用法:
SRC 源地址,DEST目标地址
这个命令可以在服务器也可以在客户端运行,所以他的登陆可以是SRC端,也可以DEST端.不管怎么样,前边是源后边是目标.
