This is a wrapper around rsync. Of course you could just use the command action to call rsync yourself, but you also have to add a fair number of boilerplate options and host facts. You still may need to call rsync directly via `command' or `shell' depending on your use case. The synchronize action is meant to do common things with `rsync' easily. It does not provide access to the full power of rsync, but does make most invocations easier to follow. |
这是一个关于rsync的模块。
