常用定时器 #

• 自动休眠
• 清楚内存
• 更新容器内的git项目
• 定时器日志需要安装邮箱 apt install postfix -y (选择5. Local only)日志在/var/mail/用户下

*/10 * * * * echo 3 > /proc/sys/vm/drop_caches
0 */2 * * * docker exec zian updategit

powersave.sh #

• 两小时自动关机
• debian13需安装sudo su root + apt install -y wtmpdb

更新mtproto #

• 编辑配置文件
• 编写mtproto.sh,防止空返回加多一次curl
• 定时器 */10 * * * * docker exec -i zian mtproto.sh
• apt install -y nmap
