nohup如何工作? [英] How does nohup work?

问题描述

使用nohup运行程序时，幕后将执行什么操作?

What is performed behind the scenes when a program runs with nohup?

父进程的PID是否已更改?

Is the PID of the parent process being changed?

谢谢.

编辑:我了解到nohup(并取消了)会导致SIGHUP如果父进程接收到它，则不会发送给该进程.这是否意味着它等同于处理SIGHUP(并实际上忽略了它)?

EDIT: I understood that nohup (and disown) causes that SIGHUP is not sent to the process if the parent process receives it. Does it mean that it is equivalent to handling SIGHUP (and actually ignore it)?
