Notes from the video:

Users are added to the system using the following command:

# usermod user1

As part of running the usermod command it gives the user a unique UID (user ID number) and creates a group of the same name with its own GID (group ID number).

To specify the UID and GID at user creation run:

# useradd -u 1001 -g 1002 user1

To create a new group run:

# groupadd IT

To create a new user and add it to that group:

# useradd -G IT user1

To delete a user:

# userdel user1

To delete a user and their home directory:

# userdel -r user1

To rename a user:

# usermod -l user2 user1

To update the password of a user:

# passwd user1
