\[CP\]Linux根据进程名称Kill多个进程

经常需要Kill多个进程，这些进程包含共同的关键字，可以用一条命令Kill掉它们。  
ps aux | grep “cmd-test.php” |grep -v grep| cut -c 9-15 | xargs kill -9  
管道符“|”用来隔开两个命令，管道符左边命令的输出会作为管道符右边命令的输入。下面说说用管道符联接起来的几个命令：  
“ps aux” 查看所有进程的命令。这时检索出的进程将作为下一条命令grep “common”的输入。  
“grep “common” 选出所有含有关键字”common”的进程。  
“cut -c 9-15” 截取输入行的第9个字符到第15个字符，而这正好是进程号PID。  
“xargs kill –9” 中的xargs命令是用来把前面命令的输出结果（PID）作为”kill –9”命令的参数，并执行该命令。”kill –9” 会强行杀掉指定进程。

项目实例：  
项目中监控两个进程，如果进程丢失，则自动启动，另外把这个shell脚本配置在linux下面的crontab，定时执行即可！

#!/bin/bash
    pcount=$(ps -fe|grep cmd-test.php |grep -v grep|wc -l|awk '{print $1}')
    if [ $pcount -eq 2 ]
    then
            echo "running two process"
    else
            echo "process != 2,then need to restart process"
            ps aux | grep "cmd-test.php" |grep -v grep| cut -c 9-15 | xargs kill -9
            echo "process kill over,starting the process"
            nohup /usr/local/php/bin/php /data1/htdocs/xxx/bin/cmd-test.php query/execute &
            nohup /usr/local/php/bin/php /data1/htdocs/xxx/bin/cmd-test.php notice/executeCycle &
    fi
