Linux命令-read

[chenjl@ipha-dev71-1 yysoft]$ read -p "check run the script is the mysql server? (y/n) " choice
check run the script is the mysql server? (y/n) y
[chenjl@ipha-dev71-1 yysoft]$ echo $choice
y

详细解释：

p是prompt的缩写，指提示信息

read -p "check run the script is the mysql server? (y/n) " choice

以上命令回车后会显示 check run the script is the mysql server? (y/n)

之后用户输入的内容会被保存到choice变量中
