在后台启动进程，执行任务，然后在后台终止进程 [英] Start a process in background, do a task, then kill the process in the background

问题描述

我有一个如下所示的脚本:

I have a script that looks like this:

pushd .
nohup java -jar test/selenium-server.jar > /dev/null 2>&1 &
cd web/code/protected/tests/
phpunit functional/
popd

硒服务器需要运行以进行测试，但是在phpunit命令完成后，我想杀死正在运行的硒服务器.

The selenium servers needs to be running for the tests, however after the phpunit command finishes I'd like to kill the selenium-server that was running.

我该怎么做?

推荐答案

执行脚本后，将创建一个新的shell实例.这意味着新脚本中的jobs不会列出在父外壳中运行的任何作业.

When the script is excecuted a new shell instance is created. Which means that the jobs in the new script would not list any jobs running in the parent shell.

由于selenium-server服务器是在新脚本中创建的唯一后台进程，因此可以使用以下命令将其杀死

Since the selenium-server server is the only background process that is created in the new script it can be killed using

#The first job 
kill %1

或

#The last job Same as the first one
kill %-
