rc.local会阻塞直到命令执行完毕吗? [英] Will rc.local block until command finish execution?

问题描述

rc.local将等待每个命令完成，还是像exec()一样执行命令?

Will rc.local wait for each command to finish, or the commands are executed like exec() ?

推荐答案

这是一个普通的shell脚本.因此，根据脚本调用命令的方式(例如，是否使用&)，它们是否阻塞.

It's a normal shell script. So they block or not, according to how the script invokes the commands (e.g. with/without &).

但是exec的工作方式也与您的思维方式不同； exec()不会异步执行任何操作.

But exec also works differently to how you appear to think; exec() doesn't do anything asynchronously.
