读取 Bash 脚本的输入

Question

我正在学习 shell 脚本，我想获取变量的输入

mynum 

我的脚本不起作用：

#!/bin/bash

mynum

echo -n "Please enter the number to validate--->"
read mynum

if [ mynum -eq 100 ]
then
    echo "mynum is equal to 100"
else
    echo "mynum is not equal to 100"
fi

帮帮我吧。

Answer 1

最后我得到了它 ！！！

#!/bin/bash

read -p "Please enter the number to validate :" mynum

#mynum=234

if [ $mynum -eq 100 ]
then
    echo "mynum is equal to 100"
else
    echo "mynum is not equal to 100"
fi



./is
Please enter the number to validate :345
mynum is not equal to 100
