command | up

up (Ultimate Plumber) lets you build complex shell pipelines interactively by showing instant live preview of command results as you type. The pipeline is passed to bash, so all bash features work. Press Ctrl-X to save the final pipeline to a script file. The input buffer is capped at 40 MB.

up was created by Mateusz Czaplinski (akavel) and is written in Go.
