Linux terms
The operating system underneath almost everything in production
Linux runs the servers, containers, and cloud instances that power most production software. This category covers shell commands, file systems, process management, permissions, networking tools, cron jobs, and the system internals that every backend developer benefits from understanding. Knowing your way around Linux is not optional when something breaks at 2am.
