守护进程为什么叫守护进程？
Why are daemons called daemons?
想知道调用守护程序或线程的历史原因“daemon”
让我心痒了很久
Lat: daemon, latin version of the Greek "δαίμων" ("godlike power, fate, god")
- god,
- a subordinate deity, as the genius of a place or a person's attendant spirit
有许多问题阐明了 daemons are and how they behave 的含义，但 none 解释了术语 “守护进程” 的起源，用于 运行在背景中 sshd.
为什么我们将后台 运行 的程序命名为守护进程？
根据维基百科：
这个词是由 MIT Project MAC 的程序员创造的。他们的名字取自麦克斯韦妖，这是一个来自思想实验的虚构存在，它不断在后台工作，对分子进行分类。
Unix 系统继承了这个术语。麦克斯韦的恶魔与希腊神话对守护进程的解释是一致的，它是在后台工作的超自然存在，没有特别的善恶偏见。但是，BSD 及其一些衍生产品采用基督教恶魔作为吉祥物，而不是希腊守护进程。

According to Fernando J. Corbato who worked on Project MAC in 1963 his
team is the first to use the term daemon. The use of the term daemon
was inspired by Maxwell's daemon, in physics and thermodynamics as an
imaginary agent which helped to sort molecules.
"We fancifully began to use the word daemon to describe background
processes which worked tirelessly to perform system chores."
In the Unix System Administration Handbook, Evi Nemeth states the
following about daemons:
"Many people equate the word "daemon" with the word "demon", implying
some kind of satanic connection between UNIX and the underworld. This
is an egregious misunderstanding. "Daemon" is actually a much older
form of "demon"; daemons have no particular bias towards good or evil,
but rather serve to help define a person's character or personality.
The ancient Greeks' concept of a "personal daemon" was similar to the
modern concept of a "guardian angel"—eudaemonia is the state of being
helped or protected by a kindly spirit. As a rule, UNIX systems seem
to be infested with both daemons and demons."
