You can create a new user account in Linux by following these steps:
Open a terminal window.
Switch to the root user account using the su command and entering the root user's password.
Run the adduser command to create a new user. Replace newusername with the desired username for the new account.
Set a password for the new user by running the passwd command and entering a new password when prompted.
Optionally, you can also add the new user to a specific group using the usermod command. Replace groupname with the desired group name.
usermod -a -G groupname newusername
usermod -a -G developer rakesh
Exit the root user account by running the exit command.
