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
#!/bin/bash

## NUM='3 5 7'

## 检查输入的数字个数是否为 3 个
function CT () {

}

## 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 () {

}

## 判断是否有重复的数字
function SN () {

echo "ERROR! There have same number : '$*'"
exit 4
