语言: Shell (Bash)

运行方式:

sh num-game.sh 数字1 数字2 数字3

如果不想使用传递数字的方式, 可以修改 num-game.sh 第 9 行, 将

NUM=$*

改为

NUM='数字1 数字2 数字3'

然后直接运行 sh num-game.sh 即可

复制代码 代码如下:

#!/bin/bash

## Author : TaxKiz

## Email : taxkiz@gmail.com

export PATH='/bin:/sbin:/usr/bin:/usr/sbin'

## NUM='3 5 7'

NUM=$*

## 检查输入的数字个数是否为 3 个

function CT () {

[ $( echo $* | sed 's/ /n/g' | wc -l ) != '3' ] && echo " Please Enter 3 Number ! " && exit 1

}

CT $NUM

## 个位数列表

NT='1/2/3/4/5/6/7/8/9'

## 检查输入的数字是否为个位数

function CK () {

for num in $*

do

[ $num == '0' ] && echo "Error Number '$num'" && exit 2

echo $NT | grep "b$numb" > /dev/null 2>&1

[ $? != '0' ] && echo "$num is not a single digit" && exit 3

done

}

CK $NUM

## 判断是否有重复的数字

function SN () {

if [ $1 == $2 ] || [ $1 == $3 ] || [ $2 == $3 ]; then

echo "ERROR! There have same number : '$*'"

exit 4

fi

}

SN $NUM

## 大喊一声

function GO () {

A1=$1

A2=$2

A3=$3

T1=$(( $1 * $2 ))

T2=$(( $1 * $3 ))

T3=$(( $2 * $3 ))

TA=$(( $1 * $2 * $3 ))

for num in {1..100}

do

echo $num | grep $A1 > /dev/null 2>&1

[ $? == '0' ] && echo 'Fizz' && continue

echo "scale=2; $num/$TA" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'FizzBuzzWhizz' && continue

echo "scale=2; $num/$T1" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'FizzBuzz' && continue

echo "scale=2; $num/$T2" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'BuzzWhizz' && continue

echo "scale=2; $num/$T3" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'FizzWhizz' && continue

echo "scale=2; $num/$A1" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'Fizz' && continue

echo "scale=2; $num/$A2" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'Buzz' && continue

echo "scale=2; $num/$A3" | bc | grep 00 > /dev/null 2>&1

[ $? == '0' ] && echo 'Whizz' && continue

echo $num

done

}

GO $NUM
