python+rsync如何精确同步指定格式文件-创新互联
这篇文章主要介绍了python+rsync如何精确同步指定格式文件，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
具体内容如下
# coding: utf-8
#!/usr/bin/env python
'''
updatedb更新本地服务器指定目录/home/upload/de locate.dbz数据库
然后locate命令正则查找符合条件的文件并将文件名输出到locate.src
通过paramiko模块得到远程服务器符合条件的文件并将文件名输出到locate.dst
比较这两个文件得到locate.diff，最好rsync命令同步locate.diff列表中的文件
到远程服务器
