跳板机定期改密码脚本

很早写的，最近别人问过一次，贴出来吧。

#!/bin/bash

nowmonth=`date +%m`
nowday=`date +%d`

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 "[email protected]*.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
}

                D=$(expr $nowmonth \* 30 + $nowday - $day  - `expr $month \* 30`)
                if [ $D -gt 85 ];then
                        GaiMiMa $user

        else
