shell随机定时修改密码change_passwd.sh

change_passwd.sh

#!/bin/sh
/usr/bin/chattr -i /etc/passwd /etc/shadow /etc/group /etc/gshadow
/usr/bin/echo `/usr/bin/date +%y%m%d%w` |/usr/bin/awk -f '' '{print $1$5$9"jack_cui"$3$5$7}' |/usr/bin/passwd --stdin root
/usr/bin/chattr +i /etc/passwd /etc/shadow /etc/group /etc/gshadow

定时任务 crontab -e

#change_passwd
0 10 10,25 * * /bin/sh /srv/change_passwd.sh >/dev/null 2>&1

ps：下面看下shell 随机修改密码

#!/bin/bash

name=hostname
eth1=""
if ifconfig eth1 &> /dev/null;then
eth1=$(ip a | grep -a 0 "eth1" | awk -f "[ /]" '/inet/ {print $3}')
fi
eth0=$(ip a | grep -a 0 "eth0" | awk -f "[ /]" '/inet/ {print $3}')

matrix1="0123456789"
matrix2="abcdefghijklmnopqrstuvwxyz"
matrix3="abcdefghijklmnopqrstuvwxyz"
matrix4="./*&^%$#@!()"

length="16"

ii=1
while [ "${n:=1}" -le "$length" ]; do
matrix=eval echo "$"matrix${ii}
pass="$pass${matrix:$(($random%${#matrix})):1}"
let n+=1
ii=expr $ii + 1
if [ $ii -eq 5 ];then
ii=1
fi
done
echo "$pass" | passwd root --stdin
echo "$eth1 $eth0 $name root $pass" >> /tmp/pass.txt
cat /tmp/pass.txt
rm -rf /tmp/pass.txt 
rm -rf /root/test.sh
