You've been doing Windows development before, and Linux is required in recent projects. As a small rookie, hurriedly bought a classic book "Bird Brother's Linux private dishes" study. Recently there was a small task- because the product generated a lot of log, and grew fast, so you need to use the script (Bash scripts) to delete the expired log file .Using cron job under Linux can be a good solution to this problem.　　What is a

Solaris is open source, both for sun and for the open source community, which is a blockbuster. For Sun, this is an open source for one of its three pillars, and the future development of Solaris is a concern. Similarly, people interested in Open-source software believe that open source Solaris may pose a threat to Linux. For a while, the debate about

IntroductionA timed task (cron Job) is used to schedule commands that need to be executed periodically. With it, you can configure certain commands or scripts to run periodically over a set period of time. Cron is one of the most useful tools in Linux or Unix-like systems. The Cron Service (daemon) runs in the background of the system and continuously checks the/

Linux's implementation of php's scheduled cron task does not have a solution for PHP itself to execute the scheduled task, but it is completed by using the sleep function. In this way, you need to make some configuration in advance, such as the implementation process: The code is as follows:Ignore_user_abort (); // close the browser and run the PHP script.Set_time_limit (0); // use set_time_limit (0) to allow unlimited execution of the program$ Inte

In linux, php regularly executes cron tasks. There is no solution for PHP itself to execute scheduled tasks, but it is completed by using the sleep function. This approach requires some configuration in advance, such as the implementation process: copying code does not have a solution for PHP itself to execute scheduled tasks, but it is completed by using the sleep function. In this way, you need to make some configuration in advance, such as the impl

The format of the Quartz cron expression is very similar to that of the UNIX cron format, but there is still a little obvious difference. One of the differences is that the Quartz format supports scheduling down to the second level, while the UNIX cron program only supports up to minute levels. Many of our trigger plans are based on a second-level increment (for
