sh Bash脚本根据exif数据和文件时间戳移动图像

Posted 2021-05-07

#!/bin/bash

# Reads EXIF creation date from all .JPG files in the
# current directory and moves them carefully under
#
#   $BASEDIR/YYYY/YYYY-MM/YYYY-MM-DD/
#
# ...where 'carefully' means that it does not overwrite
# differing files if they already exist and will not delete
# the original file if copying fails for some reason.
#
# It DOES overwrite identical files in the destination directory
# with the ones in current, however.
#
# This script was originally written and put into
# Public Domain by Jarno Elonen <[e-mail]> in June 2003.
# Feel free to do whatever you like with it.
