Three, the difference between useradd and adduser

1. useradd will only create a user name, and will not create a user directory under the home path, nor will it create a password. Therefore, using this user to log in to the system cannot log in. In order to avoid this situation, you can use (useradd -m + username), it will create a folder with the same name in the /home directory, and then use ( passwd + username) to set a password for the specified username.

2.adduser creates a new user (adduser + username) so that a folder with the same name will be automatically created in the /home directory
