很多時候我們不能一直守護在自己的電腦旁邊，而且有些文件并不想讓別人知道。那么這時候來個鎖屏，是再合適不過的了。今天分享一個自制的鎖屏工具，如下。
準備
•操作系統 : 我這里是ElementaryOS虛擬機 + XShell 遠程登錄工具
•Shell語言 ： 我使用的是默認的Bash Shell
•其他小工具 :
?fortune：系統隨機的從語庫中選出一句英文成語。
?cowsay : 在終端界面上顯示出一個奶牛的語句框，配合管道連接上fortune，效果完美！

運行演示
程序運行開始：
mark@mark:~/temp/myscripts$ ./lockscreen.sh
______________________________________
/ Please input the password you \
\ will use later! /
--------------------------------------
\ ^__^
\ (oo)\_______
(__)\ )\/\
||----w |
|| ||
123
Screen will locked in 7 seconds!
由于靜態文本沒辦法顯示程序執行過程中的動態效果，所以直接看解鎖界面吧
當我們輸入不正確的密碼的時候，系統會提示輸入錯誤，以及一個幽默的“警告”
___________________________
/ \
\ Please enter unlock code: /
---------------------------
\ ^__^
\ (oo)\_______
(__)\ )\/\
||----w |
|| ||
Do not check my files,please! See as follows:
_________________________________________
/ Q: Why is it that the more accuracy you \
| demand from an interpolation |
| |
| function, the more expensive it becomes |
| to compute? A: That's the Law of Spline |
\ Demand. /
-----------------------------------------
\ ^__^
\ (oo)\_______
(__)\ )\/\
||----w |

當我們密碼輸入正確的時候，如下：

/ \
\ Please enter unlock code: /

\ ^__^
\ (oo)\_______

||----w |

Hello mark,Today is 06:35:05
結語
代碼還是很簡單的，僅僅用到了shell腳本語法的幾個小命令。希望我這個腳本能拋磚引玉，打開你的思路，做出更好的鎖屏小腳本！
