  ubuntu user to build the best use adduser, adduser and useradd though is the same as in other linux system which, but when I use useradd, did not create the user's home directory with the same name in ubuntu.

  # 新建用户，会创建同名的用户主目录
  adduser user1
  # ubuntu查看用户列表
  cat /etc/passwd
  # 用linux代替想要删除的用户账户， -r 表示连同用户主目录一块删除
  userdel -r user1
  # 查看是否正确删除用户：
  id user1
