Csv

A lightweight collection of bash scripts for common CSV operations without reaching for Python or specialized tools. You get four utilities: analyze for quick stats, filter for pulling rows by column value, select for column extraction, and sort with numeric and reverse options. It's all standard Unix tools under the hood (awk, cut, sort, grep), so it's fast and has zero dependencies beyond bash. Honestly best suited for quick data exploration or pipeline preprocessing where you don't want the overhead of loading pandas. If you're already in a terminal and need to slice up a CSV file fast, this does the job without ceremony.
