My Favorite 5 Command Line Tools
summary
Rapid demos show five concrete tools and what they actually do: sdkman installs and switches OpenJDK builds (installs Zulu, runs Java 23 → 17 switch), ezaa replaces ls with colored, tree-style listings and aliases to LL, ffmpeg rescales 720→480, transcodes MP4→AVI with libx264 and preset veryslow while copying audio, and pueue queues and follows jobs (killing a hung job before retry). Watchexec watches a directory to trigger commands and find is used to move all MP4s into a finished folder; demos have small Wi‑Fi and demo hiccups but complete successfully.
