Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

This article mainly introduces in detail the implementation of Shell number guessing game for everyone, the sample code in the article is very detailed, has a certain reference value, interested friends can refer to it.

This paper gives you an example to share the specific code of Shell to realize the number guessing game for your reference. The specific contents are as follows.

When you are new to Shell, you need to use shell to accomplish a variety of small goals, such as entering a date, calculating what day it is, or writing a Mini Game.

First of all, I would like to introduce a concept that is RANDOM,random (). The random function returns a random number between 0~num-1. Random (num) is a macro definition in stdlib.h, and both num and function return values are integers.

Here is the content of the script

#! / bin/bash # guess number game Init () {echo "# #" echo "echo" Guess Number Game "echo"echo" # # "} game () {number=$ [$RANDOM0] while: doread-p" enter the number you want to guess: "n1n2 = `echo $N1 | sed's / [0-9] / / g '`if [!-z $N2] then echo" you did not enter a number. " Continuefiif [$N1 = = $number] then echo "you guessed it." Read-p "do you want to play again? (yes/no)" an1 while true do case $an1 in yes) game break;; no) break;; *) exit esac done break elif [$N1-gt $number] then echo "big guess." Continue else echo "guessed small." Continue fidone} while truedoinitecho "1: Start Game" echo "0: exit" read-p "please input 0-1:" NUM case $NUM in1) game break;; 0) break;; esac done

This script is added to the simple number guessing game, and you can choose whether to do it again or not.
