代碼echo錯誤，沒有任何數字排序，求高手指導錯在哪了？輸出沒有數字：“order after arrangement is: , , ”
腳本如下：
#!/bin/bash
read -p "please write a integer:"num1
read -p "please write a integer:"num2
read -p "please write a integer:"num3
tmp=0
if [ $num1 -gt $num2 ];then
tmp=$num1
num1=$num2
num2=$tmp
fi
if [ $num1 -gt $num3 ];then
tmp=$num1
num1=$num3
num3=$tmp
fi
if [ $num2 -gt $num3 ];then
tmp=$num2
num2=$num3
num3=$tmp
fi
echo "order after arrangement is:$num1,$num2,$num3"
