开始使用

由于需要下载多个画师的插画,这里需要使用–input-file参数。

首先创建一个gallery-dl目录作为下载路径:

mkdir gallery-dl

然后编写twitter_dl.sh代码如下

#!/bin/bash
dir=/root/gallery-dl
cd $dir && /root/.pyenv/versions/3.8.6/bin/gallery-dl --input-file list.txt

twitter_dl.sh放在gallery-dl目录下,赋予权限:

chmod +x gallery-dl

然后在当前目录创建list.txt文件:

touch list.txt

自己用vim或者其它任意编辑器将需要下载的画师的推特账户链接粘贴到list.txt里面,一行一个;

list.txt文件示例:

https://twitter.com/BillGates

定时执行

最后定时任务加入这个脚本即可,定时任务的使用不再详细赘述,谷歌即可;

/bin/bash /root/gallery-dl/twitter_dl.sh
