来源：互联网发布：nba2konline张伯伦数据编辑：程序博客网时间：2024/05/19 09:12

一、过滤出一个月之前的iperf进程

$2 是进程号

$5 是进程的启动日期

$7 是进程的持续时间

[root@hzaptb-iperf-server1 ~]# ps -ef | grep iper | awk '{print $2" "$5" "$7}' | grep `date "+%b%d" -d "last month"|cut -c 1-3`

[root@hzaptb-iperf-server1 ~]# ps -ef | grep iper | awk '{print $2" "$5" "$7}' | grep `date "+%b%d" -d "last month"|cut -c 1-3` | awk '{print "kill -9 "$1}'
kill -9 2173
kill -9 2632

三、批量kill 掉进程

[root@hzaptb-iperf-server1 ~]# ps -ef | grep iper | awk '{print $2" "$5" "$7}' | grep `date "+%b%d" -d "last month"|cut -c 1-3` | awk '{print "kill -9 "$1}'|bash

也可以用xargs 命令来批量删除进程

[root@hzaptb-iperf-server1 ~]# ps -ef | grep iper | awk '{print $2" "$5" "$7}' | grep `date "+%b%d" -d "last month"|cut -c 1-3` | awk '{print $1}'|xargs kill -9

四、查看结果是不是已经clear完毕
[root@hzaptb-iperf-server1 ~]# ps -ef | grep iper | awk '{print $2" "$5" "$7}' | grep `date "+%b%d" -d "last month"|cut -c 1-3` | wc
0 0 0
