maintain the absolute path in the program. 3. Additional issues and the purpose of solving this script is to determine whether the osgi program is running. If it is not running, it is started. The implementation idea is to run ps-elf to get the process id and status. If the id does not exist, it is started. If the id exists but the status is not running (solaris is O, AIX is ), then the original process is killed and restarted. It is found that the p

Linux configuration timed tasks, we all know the use of crontab this system function, but sometimes we need to distinguish between user execution, the following directly say the difference between the 2 ways:Method 1:Use the command crontab-e and edit the timed script directly.After this execution, the user-defined, will be written to the/var/spool/cron directory, generate a file with the user name consiste

I spent most of my time teaching courses on Solaris internal implementation, device drivers, and kernel crash dump analysis and debugging. When explaining to students how to implement various subsystems in Solaris, they often ask "How is it implemented in Linux ?" Or "this is implemented in FreeBSD, but in Solaris ?". This article discusses the three basic subsys

1. Edit the Scheduled task list using the CRONTAB-E commandThe list of scheduled tasks edited with this command is user-level, and a file with the same user name is generated in the/var/spool/cron directory after the first edit, and the file content is our scheduled task list.

Crontab on B, thus enabling remote disaster recovery of the data. 2/crontab Crond is a daemon that is used to periodically perform certain tasks or wait for certain events under Linux, similar to Scheduled tasks under Windows, when the operating system is installed, the Service tool is installed by default and the Crond process is started automatically. The Crond process periodically checks to see if ther

Crontab avoids repeated tests that have not been executed within the cycle. crontab instance If a script is running for 30 minutes, you can set the script interval to at least one hour in Crontab to avoid conflicts. The worst case is that the script is not completed within the execution cycle, and the second script starts to run again. How can we ensure that only

So I thought that using the django-crontab plug-in can satisfy my needs, the following describes how to use this plug-in. First, use pip to install the django-

One: 1. Planning a task is a task that performs the planned work at the agreed time, which is the surface meaning. In Linux, we often use cron servers to do this work. the cron Server can perform specific work based on the time specified in the configuration file. For example, we can contract in the configuration file every morning 4 points, the HTTPD server restart, this is a scheduled task;2.Cron is a timed execution tool under LinuxCron is a built-in service for Linux, but it does not autom
