up

up is the Ultimate Plumber, a tool for writing Linux pipes in a terminal-based UI interactively, with instant live preview of command results. 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. To start using up, redirect any text-emitting command (or pipeline) into it. Use PgUp/PgDn and Ctrl-[←]/Ctrl-[→] for basic browsing through the command output. In the input box at the top of the screen, start writing any bash pipeline; then press Enter to execute the command you typed, and the Ultimate Plumber will immediately show you the output of the pipeline in the scrollable window.
