sud

SUD (Super User Do) is a lightweight UNIX tool designed for privilege escalation, enabling designated users in specific system groups (admin, wheel, sudo, or sud) to execute commands with root permissions without a password. It prioritizes simpler code and easier audits compared to traditional tools like sudo, while offering a public domain license and a literate programming approach for improved readability and maintainability. Notably, SUD features a minimalistic design with fewer dependencies and no configuration files, making it suitable for specific multi-user privilege isolation scenarios.
