如何在 shell 脚本或 PHP 中每 30 分钟自动运行一次代码？

Question

I have a code which I want to run every 30mins. Since it is not possible to do it manually over 30 days I wanted to make it an automated process. Please suggest me how to do it. I want to execute this command in Putty.

--user root --host 10.0.2.140 --port 3306 --socket /var/lib/mysql/mysql.sock 

Answer 1

Use crontab , your entry would look like this:

*/30 * * * * /path/to/your/command

Answer 2

Unix and derivatives use Cron Jobs

Windows uses scheduled tasks.

Note that there are also some Cron clone implementations for windows available if you prefer.
