Systemd timer can be used to replace Cron for job scheduler. A timer file must be accompanied by a service file with the same name by default (except for the suffix). The service is triggered when the timer elapses. Because Omarine 6.0 does not use dcron, I write this article to guide you to create your own timer if needed.
We begin with a timer updating virus database that has been set up in Omarine 6.0. That is the pair of timer file clamav-freshclam.timer and service file clamav-freshclam.service.
Generally the version and release concepts can be used interchangeably. For example, version Omarine 6.0 and release Omarine 6.0 are the same. But they may be slightly different. The easiest way to clarify this is to state the following:
“We release this version second time.”
However, in RPM package management (and perhaps other package manager programs) there is no difference between version and release. This is to ensure the cleanliness of the system when installed. A new release of a package is a new version. Old package is upgraded to new package and the old package is removed.
A package with a new version number is of course a new package, called a new version or new release. But a package with the same version number but with a new release number when it is rebuilt, is also considered a new package, so is also a new version or new release. In this case, although the package was rebuilt with the same source code version but the dependencies have changed, so it has the new functionality.
When building open source packages, we don't just get binary packages. The bigger, we approach the scientific and technical achievements and observe the evolution of scientific and technical activities in the world. The scientific and technical achievements in the world are finite, but your imagination and your creative potential based on it are limitless.
