如何在Mac上使用python修改文件修改日期？

Question

Title says it all. I am trying to modify the file modification dates of folders. touch t- YYYYMMDDhhmm command from terminal does it, but it also changes the file creation date, which I do not want to change.

Is there a solution to this problem?

Answer 1

os.utime can be used to change the modification and/or access time of a file.

It accepts a descriptor or path-like object, and a tuple of times in either seconds or nanoseconds. These specify the latest access and modification times, respectively. For example:

>>> import os
>>> with open('tmp', 'wt') as f: pass
...
>>> result = os.stat('tmp')
>>> print(result.st_atime, result.st_mtime)
1541131715.0 1541131715.0
>>> os.utime('tmp', (result.st_atime, result.st_mtime + 1.0))
>>> result = os.stat('tmp')
>>> print(result.st_atime, result.st_mtime)
1541131715.0 1541131716.0
