- Command-line tools can process data 235x faster than a Hadoop cluster for certain tasks.
- Shell commands enable parallel processing, similar to distributed systems like Hadoop or Storm.
- Stream processing with shell commands uses minimal memory compared to batch processing.
- Example provided: analyzing chess game results from PGN files using grep, awk, and parallel processing with xargs.
- Optimized pipeline achieved 270MB/sec processing speed, significantly outperforming Hadoop's 1.14MB/sec.
- Key takeaway: Use simpler, single-machine tools when possible instead of over-engineering with distributed systems.
