summary
Shows concrete snippets: a bash script launches Marathon/DCOS with a JSON file and exits on missing commands, proving quick operational glue that “gets the job done”; a make recipe packs three components into one archive and calls recursive builds for each component, showing readable reproducible releases; sed performs on-the-fly JSON version substitution and grep recursively finds company URLs in docs; author compares command-line pipelines (with jq suggested for JSON) to larger Spark/Hadoop jobs and demonstrates the small-scale approach often wins.
