用c语言输出国际象棋（如何用shell脚本实现打印国际象棋棋盘）

今天主要分享一个有趣的shell脚本，实现打印国际象棋棋盘，主要看里面的逻辑是怎么实现的。

#!/bin/bash #set chess cell's width read -p "Please set the chess cell's width( two space width as unit ):" width if [[ $width =~ "^[0-9] $" ]];then echo "wrong width setting, check your input and try again." exit fi let width=$width*2 #choose player's board cell color player="player1" PS3="Which color do you want to set for $player :" select choice in red green yellow blue purple cyan white;do case $REPLY in [1-7]) if [[ $player == player2 ]];then declare -i color2=$REPLY break else declare -i color1=$REPLY fi player="player2" PS3="Which color do you want to set for $player :" ;; *) ;; esac done if (( color1==color2 ));then echo "two player must choose different color, check your choice and try again." exit fi #print the chess board for (( i=0; i<4; i )); do for (( j=0; j<$width/2; j ));do for (( k=0; k<4; k ));do echo -e "\e[4${color1}m$(printf %${width}s)\e[0m\c" echo -e "\e[4${color2}m$(printf %${width}s)\e[0m\c" done echo done for (( j=0; j<$width/2; j ));do for (( k=0; k<4; k ));do echo -e "\e[4${color2}m$(printf %${width}s)\e[0m\c" echo -e "\e[4${color1}m$(printf %${width}s)\e[0m\c" done echo done done

实现效果：
