使用Shell写一个随机发牌的脚本
#!/bin/bash points=(2 3 4 5 6 7 8 9 10 "J" "Q" "K" "A") #点数spec=("红桃" "黑桃" "方块" "梅花") #花色
poker=()
## 将点数和花色组成一副扑克
function makepoker(){
v=0;
for i in ${points[@]};do
for j in ${spec[@]};do
v=$(($v+1));
if [[ $j == "红桃" || $j == "方块" ]];then
poker[$v]="\033[33m"$j"=>"$i"\033[0m";
else
poker[$v]=$j"=>"$i;
fi
done;
done;
}
## 使用递归函数，生成随机扑克索引
function seed_random(){
if [[ ${#poker[@]} != 0 ]];then
if [[ ${#porker[@]} == 1 ]];then
return 0
else
k=$(rand 0 52);
#echo $k
if [[ ${poker[$k]} == "" ]] ;then # 当随机数不再数组时在生成一个随机数，直到随机数为数组的索引，且值不为空
seed_random
else
echo $k;
return;
fi
fi
else
return 0;
fi
}
## 生成0-52的随机数
function rand(){
min=$1
max=$(($2-$min+1))
num=$(date +%s%N)
echo $(($num%$max+$min))
}
## 随机发牌
function deal_cards(){
echo "开始随机发牌......"
for i in {1..4};do
printf "玩家（${i}）抓牌:\n\n"
for j in {1..13};do
kv=$(seed_random)
printf "%10s${j}%s\033}"\033[0m\n"
unset poker[$kv] #将发出的牌删除
done;
printf "\n"
done;
}
echo "正在洗牌......"
makepoker
deal_cards
