用shell写的99乘法表

#!/bin/bash

for((i=1;i<=9;i++)) do for((j=1;j<=${i};j++)) do set x, y, temp,z if [ ${#i} -eq 1 ]; then x=0${i} else x=${i} fi if [ ${#j} -eq 1 ]; then y=0${j} else y=${j} fi temp=$((ij)) if [ ${#temp} -eq 1 ]; then z=0${temp} else z=${temp} fi if [ $j -eq $i ]; then echo -e "\033[32m ${x}${y}=${z}\033[0m" else echo -n -e "\033[32m ${x}*${y}=${z} \033[0m" fi done

done
