Meet up a.k.a. the Ultimate Plumber:

The main goal of the Ultimate Plumber is to help interactively and incrementally explore textual data in Linux, by making it easier to quickly build complex pipelines, thanks to a fast feedback loop. This is achieved by boosting any typical Linux text-processing utils such as grep, sort, cut, paste, awk, wc, perl, etc., etc., by providing a quick, interactive, scrollable preview of their results.
