Linux强制杀进程命令行工具

 

需求， 有时候我们会有手动启动程序， 但是又在后台， 没有像服务那样有start， 和stop的程序， 这时候需要用强制杀进程方式

涉及工具， awk， sed， xargs， kill

需求一：

　　已知端口号：

lsof -i:8001 |sed '1d'| awk '{print $2}' | xargs kill -9

 

需求二：

　　已知服务：

　　 比如我只知道要杀掉redis，但不知道redis端口号怎么办

命令：

netstat -anpo | grep python | awk -F "[ /]+" '{print $7}' | xargs kill -9

netstat -anpo | grep python | awk -F "[ /]+" '{print $7}' | xargs -i -t kill -9 {} 效果一样， 这样更方便， 问了陈总

 

在精确一点呢：

通过二次精确过滤 $6的数据

netstat -anpo | grep python |grep LISTEN| awk -F "[ /]+" '{print $7}'
