Linux 使用Shell 查询超时进程并结束kill它

#!/bin/bash

#超过120秒的
timeout=120

ps -eo pid,etime,cmd|grep "要匹配的进程" | awk '{print $1, $2}'| while read pid runtime
do

    echo "pid {$pid} has run {$runtime}"

    ##如果进程运行超过了一个小时拿到的runtime会显示 01:00:00;min和sec这里没有处理
    min=$(echo $runtime|awk '{print int(substr($0,1,2))}')
    sec=$(echo $runtime|awk '{print int(substr($0,4,2))}')

    echo "substring {$runtime} get minute: {$min}  second: {$sec}"

    c=$(($min * 60 + $sec))

    echo "运行时间（秒）: "$c

    if [ "$c" -ge "$timeout" ]
    then
        kill -9 $pid
        echo "the process $pid was killed "
    fi


done
