2017年12月20日 · 在很多linux的入门教程里面都有介绍 守护进程（Daemon），它们一般都是这么介绍的：守护进程也就是通常说的Daemon 进程（精灵进程），是 Linux 中的后台服务进程。

一些属于守护进程的 Linux 桌面环境 组件，包括 D-Bus 、 NetworkManager （在这里叫 unetwork）、 PulseAudio （usound）和 Avahi。 在一個多工的電腦 作業系統 中， 守护进程 （英語： daemon， / ˈdiːmən / 或 / ˈdeɪmən /） [2] 是一種 在后台执行，而不由用户直接交互控制的电脑程序。 此类程序会被以 进程 的形式初始化。 守护进程程序的名称通常以字母 d 结尾，以指明这个进程实际是守护进程，并与普通的电脑程序区分开来。 例如， syslogd 就是指管理系统日 …
