read -t 20 -p "Please input your name: " name
echo "input name is $name"

#-s选项隐藏输入，用于隐藏项
read -s -t 20 -p "Please enter your password: " pwd
echo -e "\n"
echo "input password is $pwd"

#-n 1表示只接收一个输入字符就会执行，不需要输入回车
read -n 1 -t 20 -p "Please input your gender[M/F]:" gender
echo -e "\n"
echo "input gender is $gender"
