/usr/lib/tmpfiles.d/tmp.conf中的x /tmp/systemd-private-%b-*是什么意思
在`/usr/lib/tmpfiles.d/tmp.conf`文件中，`x /tmp/systemd-private-%b-*`表示在每次启动时，自动清理`/tmp/`目录下以`/tmp/systemd-private-`开头并以`-*`结尾的所有文件和目录。 `%b`是一个用于替代匹配的占位符，具体指代的是`/tmp/systemd-private-%b-*`中的`%b`部分。这个占位符通常被用来动态匹配以不同字符或字符串开头和结尾的文件和目录。 大多数Linux发行版都使用`tmpfiles.d`机制来管理临时文件并进行自动清理。该机制通过配置文件中设定的规则来创建、修改和清理临时文件和目录。 希望这可以帮助到你！如果你有更多的问题，请随时提出。 [2024-01-24 15:47:55 | AI写代码神器 | 333点数解答]
