很早写的，最近别人问过一次，贴出来吧。

#!/bin/bash
#
source /etc/profile &>/dev/null
basedir=$(cd `dirname $0`;pwd)
nowmonth=`date +%m`
nowday=`date +%d`
email="$basedir/email/sendemail.sh"
function GaiMiMa() {
        user="$1"
        passwd=$(/usr/bin/mkpasswd -l 20 -d 5 -c 2 -C 4 -s 0) #mkpasswd 可以yum装下
        echo $passwd |  passwd --stdin $user
        if [ $? -eq 0 ];then
                sh $email "$user@*.com" "跳板机密码更改提示" "您的跳板机密码已经更改为: $passwd 请注意下次登录时替换此密码。【注意】不要复制空白字符；如有问题请及时找**。"
        echo "$user ::::: $passwd" >> $basedir/modify.log
        fi
}
grep "/bin/bash" /etc/passwd |grep -v "root"|awk -F: ‘{print $1}‘ > $basedir/userlist
#user=‘yanzong.chen‘
for user in `cat $basedir/userlist`
do
        month=$(chage -l $user | grep "Last password change"|awk -F: ‘{print $2}‘|awk ‘{print $1}‘)
        day=$(chage -l $user | grep "Last password change"|awk -F: ‘{print $2}‘|awk ‘{print $2}‘|tr -d ,)
        month=$(grep $month $basedir/month|awk -F‘=‘ ‘{print $2}‘)
        if [ $nowmonth -ge $month ];then
                D=$(expr $nowmonth \* 30 + $nowday - $day  - `expr $month \* 30`)
                if [ $D -gt 85 ];then
                        GaiMiMa $user
                fi
        else
                X=$(expr $nowmonth \* 30 + $nowday - `expr $month \* 30` - $day + 360 )
                if [ $X -gt 85 ];then
                        GaiMiMa $user
                fi
        fi
done
echo `date +%F` >> $basedir/modify.log
