的bash語法錯誤：未接受令牌艾利芙

Question

後，我跑了一個簡單的腳本，我得到這個消息：

我的代碼

line 9: syntax error near unexpected token elif line 9: elif [ $sales -le 20000 ];

：

#!/bin/bash 
    echo "Please enter the how much sales you have done" 
    read sales 
    if [ $sales -le 5000 ]; 
    then 
     echo "your profit is $[$sales*0.25]" 
    elif [ $sales -le 10000 ]; 
     echo "your profit is $[$sales*0.1]" 
    elif [ $sales -le 20000 ]; 
     echo "your profit is $[$sales*0.15]" 
    elif [ $sales -le 40000 ]; 
     echo "your profit is $[$sales*0.2]" 
    else 
     echo "your profit is $[$sales*0.25]" 
    fi 

Answer 1

1. 你錯過then後elif
2. 你不能在bash中做浮點數學。

你可以使用這個腳本：

#!/bin/bash 
read -p "Please enter the how much sales you have done: " sales 
if [ $sales -le 5000 ]; then 
    pp='0.25' 
elif [ $sales -le 10000 ]; then 
    pp='0.1' 
elif [ $sales -le 20000 ]; then 
    pp='0.15' 
elif [ $sales -le 40000 ]; then 
    pp='0.2' 
else 
    pp='0.25' 
fi 
echo "your profit is " $(bc -l <<< "$sales * $pp")
