process optimisation

Stop flying blind in Bash: this practical guide shows how to turn Linux’s built‑in telemetry into AI‑driven speedups—instrument commands with GNU time/sysstat, log JSON, catch regressions, predict runtimes to schedule with GNU parallel, and auto‑tune CLI flags (threads, compression via pigz) with Optuna—all locally, with copy‑pasteable snippets, no GPU or data lake required.
