There are two ways to create a user account in Linux using the command line:
1. Using the useradd
command:
This is the more powerful and flexible option, offering various flags to customize the user account creation process. Here's the basic syntax:
sudo useradd [options] username
Options:
-m
: Creates a home directory for the user.-g group
: Assigns the user to a specific group.-s shell
: Sets the default login shell for the user.-c comment
: Adds a comment describing the user account.
Example:
sudo useradd -m -g developers john_doe
This command creates a user named "john_doe" with a home directory, assigns them to the "developers" group, and uses the default shell.
2. Using the adduser
command:
This is a simpler command that acts as a user-friendly frontend for useradd
. It prompts you for the necessary information interactively.
sudo adduser username
Example:
sudo adduser jane_smith
This command guides you through entering the username, password, and other details for the new user account "jane_smith".
Important Note:
Always use sudo
before these commands as creating user accounts requires administrative privileges. Remember to choose a strong password for the new user account.
Here are some additional points to consider:
- It's recommended to avoid using the username "root" for regular user accounts.
- You can manage user accounts further using commands like
passwd
(to change password),usermod
(to modify user attributes), anduserdel
(to delete a user).
For detailed information and more advanced usage, refer to the man pages of useradd
and adduser
by typing man useradd
or man adduser
in your terminal.
