The Power of the Command Line - How Bash Can Boost Your Productivity
Talkat Open Source Summit Europe 2025 · on Tuesday, 2025-08-26· at 15:05· Elicium 1 (Elicium Level 1)·
summary
Covers concrete Bash techniques: four quoting modes, pipelines run in subshells, grouping with ( ) versus { }, and using command substitution without a subshell (bash 5.3). Shows practical features to adopt now — aliases and an R→fc alias, pushd/popd directory stack, job control (fg/bg, suspend, ctrl‑Z), readline shortcuts (Ctrl‑A/E/L, Ctrl‑B/Ctrl‑F), unlimited history and HISTIGNORE patterns, arithmetic and filename expansion, and a new GLOB_SORT‑style file‑expansion ordering option for predictable script behavior.
