Users

In Linux administration, users are one of the key components of the system. A user is an individual who has access to the Linux system and its resources. Users can be classified as regular users or system users, with different permissions and levels of access.

Regular users are created by the system administrator or by other users with administrative privileges. These users are usually created to perform specific tasks or to access certain files and directories. Regular users can execute applications and run commands, but their actions are limited to their own files and directories.

System users, on the other hand, are created by the system itself and are used to perform system tasks. These users do not have a password or shell, and they cannot log in to the system. System users are used to run system services and daemons, such as web servers, email servers, and databases.

In Linux, user management is handled by the useradd and userdel commands, which allow administrators to create and delete users, respectively. Additionally, the usermod command can be used to modify user accounts, such as changing the password or home directory. Overall, users are an important part of Linux administration, and understanding how to manage and configure them is crucial for maintaining a secure and efficient system.
