How to create new user in Linux?

 Creating a new user in Linux can be done using the useradd or adduser command. Here's how you can do it step-by-step:

1. Using useradd

The useradd command is a low-level utility to add users.

Steps:

1. Open a terminal.

2. Run the following command with root privileges:

3. sudo useradd -m -s /bin/bash username

Replace username with the desired username.

o -m: Creates the user's home directory.

o -s /bin/bash: Sets the default shell to /bin/bash.

4. Set the user's password:

5. sudo passwd username

You'll be prompted to enter and confirm the password.

6. Optional: Add the user to a specific group (e.g., sudo for administrative privileges):

7. sudo usermod -aG groupname username

Replace groupname with the desired group, such as sudo.

 

2. Using adduser

The adduser command is more interactive and user-friendly, often available on Debian-based systems.

Steps:

1. Open a terminal.

2. Run the following command:

3. sudo adduser username

Replace username with the desired username.

4. Follow the prompts to:

o Set a password.

o Provide optional information (full name, room number, etc.). You can press Enter to skip these fields.

5. Optional: Add the user to a specific group:

6. sudo usermod -aG groupname username

 

3. Verify the User

You can verify that the user was created by listing all users:

cat /etc/passwd | grep username

Or by checking the home directory:

ls /home

The new user's home directory should appear there.
