从联机帮助页：

-m, --create-home
    Create the user's home directory if it does not exist. 
    The files and directories contained in the skeleton directory
    (which can be defined with the -k option) will be copied to 
    the home directory.

    By default, if this option is not specified and CREATE_HOME 
    is not enabled, no home directories are created.

但是，我强烈建议不要像使用-d /home/students/student/"${firstname}.${lastname}". 想想像“John A. Doe”这样的（真实的）用户名。他的 $HOME 目录将包含一个空格，这对用户来说并不完全友好。
