最近 , 前端同事有个需求是把本地的图片视频转成base64的json文件. 由于量比较多 , 且繁琐. 我花了点时间写了个简单的工具
https://github.com/mmfei/bash_image_to_base64
使用方式

# print base64 code
sh ./image_to_base64.sh ~/Downloads/testImage png,gif,jpg
# save to json code
sh ./image_to_base64.sh ~/Downloads/testImage png,gif a.json
# if Permission denied
# chmod +x image_to_base64.sh

直接贴源码 , 确实简单
