## What it is
up (Ultimate Plumber) is a terminal-based interactive tool for building Linux shell pipelines with instant live preview of results. It lets you pipe any text-emitting command into it and incrementally write bash pipelines while viewing scrollable output in real time.

## Use cases
- interactively explore textual data in the terminal
- build complex shell pipelines with instant feedback
- preview output of grep, awk, cut, sort pipelines live
- incrementally write and test bash pipelines
- save a finished pipeline to a shell script file
- debug long-running command output interactively

## When to choose
- you frequently compose multi-stage text-processing pipelines and want a fast feedback loop
- you want a scrollable live preview of command output while writing a pipeline
- you work mostly in a Linux/macOS terminal with standard text utils

## When to avoid
- you need structured (binary or JSON-schema-aware) data exploration rather than text lines
- you are on Windows without a Unix-like shell environment
- you need a GUI or IDE-integrated data explorer
