Practical Unix for Ruby & Rails

on YouTube ↗39m

" summary

Shows concrete shell recipes: use tail -f | grep to filter Rails logs, sed to normalize numeric IDs, then sort uniq -c to get hit counts (example yields token hits like 2667). Replaces slow editor searches with ag, pipes filenames into xargs to run only relevant specs, and detects running servers with lsof to choose spork/zeus/nailgun/Bundle invocations. Includes a reusable bash script that auto-selects the fastest test runner and explains how pipelines spawn concurrent processes with OS buffering.
