1. Requirement background for large companies, there must be a site or configuration file updates from time to time, and the use of the machine is certainly a lot of units, less than a few, more than dozens of or even hundreds of Taiwan. Therefore, automatic synchronization of files is critical.

3. Core commandrsync -av --files-from=list.txt / [email protected]:/
