Miller is a command line tool that combines features from sed, awk, cut, join, and sort. It works best on name-indexed CSV input, and thus allows easy cutting, sorting or filtering on column names. It allows pretty-printing of tabs/columns, format conversions, can be used in shell pipes like simpler tools, adds some SQL-like querying features, and is similar in spirit to "jq" the JSON queryer.
