vim grade.sh

#/bin/bash

#Verson:0.1

#Auther:diql

#Pragram:This pragram is calculation your grade

#import an argument

read -p "Please input your grade:" x

declare -i x

#jugemet $x value is none or not

IF[ "$x" == "" ];then

echo "You don't input your grade...."

exit 5

fi

#jugement the gread level

if [[ "$x" -ge "90" && "$x" -le "100" ]];then

echo "Congratulation,Your grade is A."

elif [[ "$x" -ge "80" && "$x" -le "89" ]];then

echo "Good,Your grade is B."

elif [[ "$x" -ge "70" && "$x" -le "79" ]];then

echo "Ok.Your grade is C."

elif [[ "$x" -ge "60" && "$x" -le "69" ]];then

echo "Yeah,Your grade is D."

elif [[ "$x" -lt "60" ]];then

echo "Right,Your grade is F."
