linux – 仅杀死特定Java jar的进程(实例)

我需要创建自动脚本,它会杀死特定Java JAR的运行进程.

我像这样手动完成：

jps -v

6753 Jps
4573 myJarToKill.jar
4574 notMyJarToKill.jar
4576 myJarToKill.jar

我根据JAR名称选择特定进程,例如myJarToKill.jar并运行以杀死它们.

kill 4573 4576  

是否有可能通过这样的grep或sth获得这些进程的数量？通过它来杀死命令？

解决方法:

要使用的命令是grep,awk和xargs unix命令的组合：

jps -v | grep "<your file name>" | grep -v "<if you need to exclude other output>" |awk '{print $<field number>}'|xargs kill -<kill signal>

在执行之前,请阅读以下说明：

首先运行这个：
    jps -v | grep“myJarToKill.jar”| awk'{print $1}’

Note:
$2 means that the ps output is splitted in space separated field.
So when you run the command for the first time please check that awk '{print $2}' output is the expected result otherwise you should change the field number $2 with the ones that you need.

如果“notMyJarToKill.jar”仍然存在,请添加：

jps -v  | grep "myJarToKill.jar" | grep -v "notMyJarToKill.jar"| awk '{print $1}' 

然后,如果输出结果包含您要杀死的pid,则可以运行此命令

jps -v  | grep "myJarToKill.jar" | awk '{print $1}'|xargs kill -9 

Note: you Could also use kill -TERM it’s depend by your needs.
