About:
Up is a command-line tool designed to simplify the creation of interactive command-line pipelines. It provides an instant live preview of the output as you type, making it easier to build and debug complex shell commands. This visual feedback loop significantly speeds up the process of data filtering and transformation directly in the terminal.
Key Features:
  • Instant live preview of command output
  • Interactive query building for text processing
  • Supports standard Unix tools and pipes
  • Terminal-based user interface
Use Cases:
  • Building and debugging complex grep, awk, or sed commands interactively
  • Quickly exploring and filtering structured text data like logs or CSVs
  • Creating ad-hoc data processing pipelines with real-time feedback
Alternatives:
  • bash – Standard shell requires manual execution; Up provides a live, interactive environment for building pipes.
  • jq – jq is specialized for JSON; Up is a more general-purpose tool for any text-based pipeline with a visual interface.
