V2EX child process

Child Process

定义 Definition

child process(子进程):在操作系统中,由另一个进程(父进程,parent process)创建出来并由其派生的进程。子进程通常会继承父进程的一些资源与环境(如部分文件描述符、环境变量等),并可以与父进程并发运行。(该词主要用于计算机/操作系统语境;在其他语境里也可有更一般的“派生出的过程/步骤”等含义,但不常见。)

例句 Examples

The program creates a child process to run the task in the background.
程序创建一个子进程在后台运行任务。

After the fork, the parent process waits for the child process to finish and then collects its exit status.
fork 之后,父进程等待子进程结束,并获取它的退出状态。

词源 Etymology

child 源自古英语 cild,本义为“孩子”,在技术语境中引申为“从属于、派生出的”。
process 源自拉丁语 processus(“向前推进、进行的过程”)。合在一起,child process 字面即“派生出来的进程”,用来对比其创建者 parent process(父进程)
