php Opencart - 爬过数据库查找使用的图像/ pdf，并将它们输出为简单的文本列表。 CP / Rclone / PHP可以使用此列表进行中继

Posted 2021-05-04

<?php
# Idea from: https://github.com/zenseo/opencart-needless-image
# PHP is not good enough to run this through a large store with many images
# Bash cp cant hold enough arguments from file output unless its batched
# Rclone is the best bet:
# rsync -asv --dry-run --recursive --remove-source-files --checksum --files-from=some-file.txt . destination/
