Most of the time we can't always be around our computers, and some files don't want anyone to know. So this time to a lock screen, is more appropriate. Today share a homemade lock screen tool, as follows.

Get ready

• Other gadgets:
◦fortune: The system randomly selects an English idiom from the library.
◦cowsay: in the terminal interface shows a cow statement box, with the pipe connection on the fortune, the effect is perfect!

Code

Screen'll locked in 7 seconds!

Because static text is not able to display the dynamic effect of program execution, so see the unlock interface directly
When we enter an incorrect password, the system prompts for an error and a humorous "warning"
