例如，我想杀死一个java进程，但是我的机器上正在运行多个 java 进程，那么我如何确定我想要的正确的一个？
I tried ps -ae | grep javawhich gives me all the java processes which are running, which contains tomcat, eclipse, and the one which I want to kill, but I do not understand which process to be killed?
我试过ps -ae | grep java它给了我所有正在运行的java进程，其中包含tomcat、eclipse和我想杀死的那个进程，但我不明白要杀死哪个进程？

With the psutility you can use e.g. ps auxwwwto get a lot of detail, or you may use the jpsutility to list the java processes running, eg.:
使用该ps实用程序，您可以使用例如ps auxwww获取大量详细信息，或者您可以使用该jps实用程序列出正在运行的 Java 进程，例如：
localhost:~# jps -v
2734 Bootstrap -Djava.util.logging.config.file=/opt/tomcat-6/....
2933 Launcher -Dsun.net.inetaddr.ttl=3600 -DbundleBasedir=....
10255 Jps -Dapplication.home=/usr/lib/jvm/java-6-sun-1.6.0.26 -Xms8m

I usually use
我通常使用
ps -ax|grep somethingIKnowAboutTCPOrTheArguments
ps -ax|grep somethingIKnowAboutTCPOrTheArguments
Normally the processes are launched in different directories or have a different starting-arguement. I use this to select on of my tomcats/java/....-process
通常，进程在不同的目录中启动或具有不同的起始参数。我用它来选择我的 tomcats/java/....-process
