如果我将它们删除会怎样?

and what happen if I remove them?

还是只能删除.gz文件?

or can I remove only .gz file?

谢谢.

推荐答案

否，因为它们取决于所安装的软件.但是其中一些非常重要，例如auth.log记录授权尝试，daemon.log记录守护程序活动，等等.它们用于调试，计费等.

No, because they depend of what software is installed. But some of them are very important, for example auth.log records authorization tries, daemon.log logs daemons activity, and so on. They serve for debugging, accounting and so on.

可能没有什么危险，尤其是那些.1 .2或.old.gz等.但是 logrotate 将是尝试的正确解决方案.根据分发情况，它可能易于使用(只需安装软件包)，或者可能需要完全手工制作的配置.

Probably nothing dangerous, especially those like .1 .2 or .old.gz and so on. But logrotate would be the correct solution to try; depending on the distribution it can be easy to use (just install the package) or it may require quite hand-made configuration.
