name-indexed data processing tool
Miller (mlr) allows name-indexed data such as CSV files to be processed with functions equivalent to sed, awk, cut, join, sort etc. It can convert between formats, preserves headers when sorting or reversing, and streams data where possible so its memory requirements stay small. It works well with pipes and can feed "tail -f".
