为aria2自动更新trackers

没错我又造轮子了,总觉得市面上的自动更新脚本写的都不够好,那我就自己上吧

之前在网上看到给 aria2 添加 bt-tracker 可以提升速度,经过一番搜索,找到 ngosang 大佬的 Github 仓库地址 https://github.com/ngosang/trackerslist

大佬每日勤勤恳恳的为广大用户免费更新 tracker list ,心里万分感动。但是他的格式不符合aria2的要求,不可能每次更新都手动删除那两个换行符然后改成逗号吧,那也太傻比了。所以花了半个小时写了个脚本。

if __name__ == '__main__':

用法其实很简单

参数作用
-h帮助
-p or –path自定义设置文件路径,默认是当前执行路径
-f or –file_name自定义配置文件名,默认是 aria2.conf
-t or –tracker_url自定义tracker地址, 必须是ngosang大佬的格式

用法举例:

aria2_update_trackers.py -p /home/linux/aria2 -f aria2-backup.conf

这样就可以挂在 Linux 上做自动化了
