Linux/User Management

Commands to manage user accounts in linux.

Creating a New User

The most basic implementation is:

• useradd <username>

From there, you can add argument options such as:

• -M or --no-create-home - Skips creating a home directory for user.
• -N or --no-user-group - Skips creating a group with the same name as user.
• -G or --groups - Set additional user groups user is part of, during user creation.
• -r or --system - Create a "system" account. Aka, a user with no password, no home directory, and is unable to log in.

Example:
useradd -G admins,webadmin,developers my_user
This creates a user called "my_user" that is associated with groups "admins", "webadmin", and "developers".
