20230616 Paper: The GNU/Linux Usermod Command

Abstract
The usermod command in GNU/Linux is a powerful utility that enables system administrators to modify user account attributes and settings with ease. The usermod command plays a crucial role in maintaining system security, access control, and user accountability. It allows administrators to rename user accounts, change user IDs (UIDs), adjust group memberships, modify home directories, set default shells, manage password settings, and control account expiration dates. By leveraging the usermod command, administrators can efficiently adapt user accounts to meet evolving organizational requirements, enforce security policies, and customize user environments.
Understanding the usermod command's basic syntax and available options is essential for system administrators. With usermod, administrators have the flexibility to make precise modifications to user attributes, ensuring seamless management of access privileges, resource allocation, and user-specific settings. The usermod command empowers administrators to maintain a secure and efficient computing environment by providing granular control over user accounts and their associated properties.
