Shell中怎么查殺子進程和僵尸進程

本篇文章給大家分享的是有關Shell中怎么查殺子進程和僵尸進程，小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著小編一起來看看吧。

代碼如下:

#!/bin/sh
# 遞歸找到導致進程僵死的最底層子進程并殺除.
ParentProcessID=$1;
if [ "x${ParentProcessID}" = "x" ] ; then
    echo "Please Supply the top Parent Process ID to be killed!"
    echo "Usage:sh $0 PID [-v]"
    echo "PID The Parent Process ID as root"
    echo "-v is this argument supplied,no real kill operation will be performed,only process tree be show."
    exit 1
fi

let IsRealKillDo=1;
if [ "x$2" = "x-v" ] ; then
    let IsRealKillDo=0;
fi

echo "Begin Kill the Leaf Process of process ${ParentProcessID}" >&2

killpidList=""

function loopNextSubProcess(){
    local nParentProcessID=$1
    local tmpPidList=""
    tmpPidList=`ps -A --format='%p%PisParent' --width 2048 -w --sort pid|grep "${nParentProcessID}isParent"|grep -v grep|grep -v "$$" | awk '{ printf $1 }'`
    ps --format='%p%P%a' --width 2048 -w -p ${nParentProcessID}|grep -v grep|grep -v "$$" >&2
    if [ "x${tmpPidList}" = "x" ] ; then
        echo "****Got One Leaf = [${nParentProcessID}]****" >&2
        killpidList="${killpidList}\n${nParentProcessID}"
        return
    fi

    for theNextPid in ${tmpPidList} ; do
        loopNextSubProcess ${theNextPid}
    done
}

loopNextSubProcess ${ParentProcessID}

if [ ${IsRealKillDo} -eq 1 -a "x${killpidList}" != "x" ] ; then
    for curpid in `echo -e ${killpidList}` ; do
        if [ "x${curpid}" != "x" ] ; then
            echo "kill -9 ${curpid}"
            kill -9 ${curpid}
        fi
    done
else
    echo -e ${killpidList}
fi
