[Do something with Windows shared directories on Linux mounts]

 

For the rational use of resources, the company imposes the following restrictions on a shared folder: In the personal folders of employees under this folder, files or subfolders whose last modified/access time is older than 30 days will be deleted. Deleted in a script that is executed regularly every day. However many files are large and we don't want to be deleted.

Below, the counterattack of Diaosi:

 

1) Mount the personal folder under the shared folder (such as //192.168.1.103/share/yasi) to a Linux machine

1. mount -t cifs //192.168.1.103/share/yasi /mnt/yasi -o username="yasi",password="pass"  

 

 

2) Code the following Python script on the Linux machine, /home/yasi/update_ts.py

 

[python]  view plain copy  

 

1. import os, sys, time  
2.   
3. topdir = "/mnt/yasi"  
4.   
5. def update_time(timestamp, dirname, names):  
6.         for name in names:  
7.                 timestamps = (timestamp, timestamp)  
8.                 os.utime(os.path.join(dirname, name), timestamps)  
9.   
10. os.path.walk(topdir, update_time, time.time())  

3) Add a cron job on the Linux machine as follows, that is, execute the update_ts.py script at 23:00 every day

 

crontab -e

 

[plain]  view plain copy  

 

1. 0 23 * * * python /home/yasi/update_ts.py  

Therefore, at 23:00 every day, the last modified/access time of all files and subfolders under //192.168.1.103/share/yasi will be changed to the current time, so that there will never be a "no access for more than 30 days". Files and folders are gone!

 

 

【Notice】

 

All files and subfolders in /mnt/yasi specified in update_ts.py, that is, //192.168.1.103/share/yasi, will be timestamped, but the timestamp of the folder //192.168.1.103/share/yasi itself Not modified by update_ts.py.
