freenas 自动删除文件

需求：共享扫描文件每周都要人工删除同一类型的txt文件，打算改成自动删除。用python来写试试。
`root@freenas[~/freenasscript]# cat autodeletefiles.py

#!/usr/local/bin/python
import os
from os import listdir
my_path = '/mnt/volume1/iocage/scanfolder/'
for file_name in listdir(my_path):
print (my_path + file_name + '.txt')
os.remove(my_path + file_name)
print("File removed successfully")
