Python| shutil.copystat() 方法

Python中的Shutil 模块提供了许多对文件和文件集合进行高级操作的功能。它属于 Python 的标准实用程序模块。该模块有助于自动复制和删除文件和目录的过程。
Python中的shutil.copystat()方法用于将权限位、上次访问时间、上次修改时间和标志值从给定的源路径复制到给定的目标路径。
shutil.copystat()方法不会影响文件内容以及所有者和组信息。
在 Linux 上，除了权限位、上次访问时间、上次修改时间和标志值之外，此方法还尝试复制一些扩展属性。

Syntax: shutil.copystat(source, destination, *, follow_symlinks = True)
Parameter:
source: A string representing the path of the source file.
destination: A string representing the path of the destination file.
follow_symlinks (optional) : The default value of this parameter is True. If it is False and source and destination both refers to a symbolic link then the shutil.copystat() method will operate on the symbolic links themselves rather than the files the symbolic links refer to.
Note: The ‘*’ in parameter list indicates that all following parameters (Here in our case ‘follow_symlinks’) are keyword-only parameters and they can be provided using their name, not as positional parameter.
Return Type: This method does not return any value.

输出：

Before using shutil.copystat() method:
Source metadata:
Permission bits: 664
Last access time: Mon Jun 10 00:37:16 2019
Last modification time: Thu Dec 27 00:15:23 2018

Destination metadata:
Permission bits: 777
Last access time: Fri Apr 12 01:13:25 2019
Last modification time: Thu Apr 11 02:03:45 2019

After using shutil.copystat() method:
Destination metadata:
Permission bits: 664
Last access time: Mon Jun 10 00:37:16 2019
Last modification time: Thu Dec 27 00:15:23 2018

Permission bits, last access time and last modification time
copied from source to destination successfully
