利用颜色实现的口令程序

利用颜色实现的口令程序,很简单,初级SHELL,没什么大用,挡一挡操作员也许可以.

功能:输入三次口令失败后,等待5秒钟退出..

最好加在.profile文件中,并将delete键失去作用.

[code:1:57582d4d7e]## passwd_

## 调用文件: lsmenu (背景文件)

xy()

{

_r=$1

_c=$2

_txt=$3

tput cup $_r $_c

echo -n $_txt

}

## 口令检验

password=`date +%y%d%m` #其实就是口令明码,你可以任意修改

count=3

while true

do

clear

sh lsmenu #调用背景文件

xy 6 16 "警告!!!必须经主管授权,请输入口令:\c"

echo "\c"

read passwd

echo 

if [ "$passwd" = "$password" ]; then

echo

setcolor -n

break

else

count=`expr $count - 1`

if [ "$count" = "0" ]; then

tput civis

xy 8 16 "你没有机会了...\c"

a=0

b=5

while [ $a -lt 6 ]

do

xy 8 40 $b

tput bel

sleep 1

a=`expr $a + 1`

b=`expr $b - 1`

done

tput cnorm

clear

setcolor -n

exit 1

fi

tput bel

xy 8 16 "口令错!!!还有($count)次机会...\c"

read no

fi

done

##以下可以加上你要调用的程序或命令 ..........

后来为了美观些,又加的背景文件.

[code:1:57582d4d7e]# lsmenu
