setuid: Elevating Privileges

This technical article demonstrates how to use the setuid (set user ID) permission on Linux and macOS to allow a regular user to run a compiled Go binary with root-level privileges. It includes a step-by-step guide: creating a Go program that accesses a protected file, compiling it, changing ownership to root, and setting the setuid bit to enable privilege escalation safely, similar to how sudo operates.
