例子：

echo -n "Input your favourite fruit:"

echo "Your favourite fruit is $fruit"

将读取到的内容放在变量中：

read -p "Input your name:" name
echo "Your name is $name"

-s 参数用于隐藏输入：

read -s -p "Input your passwrod:" password
echo "Your password is $password"

-a 参数用于将输入保存到数组中：

echo -n "Input your hobbies:"
read -a hobbies
echo "Your hoddies are $hobbies"

在不指定变量的情况下，read 会将输入保存到 REPLY 变量中：

read -p "Input your age:"
echo "Your age is $REPLY"
