linux井字棋shell脚本

以下是一个简单的 Linux 井字棋 shell 脚本：

#!/bin/bash

# 初始化游戏面板
board=(1 2 3 4 5 6 7 8 9)
player=1
game_on=true

# 打印游戏面板
function print_board() {
  printf "\n"
  printf "\t  %s | %s | %s\n" "${board[0]}" "${board[1]}" "${board[2]}"
  printf "\t -----------\n"
  printf "\t  %s | %s | %s\n" "${board[3]}" "${board[4]}" "${board[5]}"
  printf "\t -----------\n"
  printf "\t  %s | %s | %s\n" "${board[6]}" "${board[7]}" "${board[8]}"
  printf "\n"
}

# 检查是否有玩家获胜
function check_win() {
  if [[ "${board[0]}" == "${board[1]}" && "${board[1]}" == "${board[2]}" ]] ||
     [[ "${board[3]}" == "${board[4]}" && "${board[4]}" == "${board[5]}" ]] ||
     [[ "${board[6]}" == "${board[7]}" && "${board[7]}" == "${board[8]}" ]] ||
     [[ "${board[0]}" == "${board[3]}" && "${board[3]}" == "${board[6]}" ]] ||
     [[ "${board[1]}" == "${board[4]}" && "${board[4]}" == "${board[7]}" ]] ||
     [[ "${board[2]}" == "${board[5]}" && "${board[5]}" == "${board[8]}" ]] ||
     [[ "${board[0]}" == "${board[4]}" && "${board[4]}" == "${board[8]}" ]] ||
     [[ "${board[2]}" == "${board[4]}" && "${board[4]}" == "${board[6]}" ]]; then
    printf "Player %s wins!\n" "$player"
    game_on=false
  fi
}

# 检查是否平局
function check_tie() {
  if [[ "${board[0]}" != 1 && "${board[1]}" != 2 && "${board[2]}" != 3 &&
        "${board[3]}" != 4 && "${board[4]}" != 5 && "${board[5]}" != 6 &&
        "${board[6]}" != 7 && "${board[7]}" != 8 && "${board[8]}" != 9 ]]; then
    printf "It's a tie!\n"
    game_on=false
  fi
}

# 询问玩家下棋位置
function ask_player() {
  printf "Player %s, choose a spot: " "$player"
  read spot
  if [[ "${board[spot-1]}" != "X" && "${board[spot-1]}" != "O" ]]; then
    board[spot-1]=$mark
  else
    printf "Spot already taken, choose another spot.\n"
    ask_player
  fi
}

# 切换玩家
function switch_player() {
  if [ $player -eq 1 ]; then
    player=2
    mark="O"
  else
    player=1
    mark="X"
  fi
}

# 游戏循环
while [ $game_on == true ]; do
  print_board
  ask_player
  check_win
  check_tie
  switch_player
done

print_board

这个脚本实现了一个简单的井字棋游戏，玩家可以通过输入数字来下棋。该脚本使用了数组来表示游戏面板，并使用函数来检查玩家是否获胜、检查是否平局、询问玩家下棋位置以及切换玩家。游戏循环会一直运行，直到有一方玩家获胜或者平局。
