Managing User Accounts
To manage user accounts in Linux, you can use various command line tools such as **useradd** and **usermod**. These commands allow you to create new users, modify existing users, and manage user settings.
To create a new user, you can use the **useradd** command followed by the username you want to create. You can also specify options such as the user’s home directory and default shell.
To modify an existing user account, you can use the **usermod** command followed by the username you want to modify. This command allows you to change the user’s home directory, default shell, or other settings.
You can also manage user account settings using the **passwd** command, which allows you to change a user’s password or lock their account. Additionally, you can use the **chage** command to set password expiration dates and other account settings.
