LineSelect, shell utility to interactively select lines in a pipeline

Allows you to "pause" a shell pipeline to interactively select a subset of lines to proceed with. I've always wanted a tool like this, as it effectively combines the best of shell pipes (easy to automate) and visual file managers (easy to make selections). Now that I have it I can't believe a tool like this is not already part of the standard set of shell utilities. There are so many situations where it is useful. Tested on Linux but should also work on MacOS. Also: please help me come up with a better name!

In plain words

LineSelect is a shell utility that pauses a pipeline to let users interactively select which lines to pass forward. It combines the automation benefits of piped commands with the intuitive selection interface of visual file managers. The tool works on Linux and macOS, bridging a gap in standard shell utilities by making it easy to filter data mid-pipeline without complex scripting. It's designed for command-line users who frequently need to choose subsets of piped output.

    Hi HN! I've created a CLI tool called "ell" that allows you to interact with LLMs directly from your terminal. Designed with the Unix philosophy in mind, ell is simple, modular, and extensible. You can easily pipe input and output to integrate with other tools. Its templates and hook-based plugins enable you to customize and extend its functionality to suit any needs. Check out the README for usage instructions and examples. I developed this tool because existing solutions often felt too heavy, with many dependencies, or they weren't friendly to piping and customization. I, on the contrary,…

  • Tuc – When cut doesn’t cut it2022 · github.com · ▲241

    Announcing `tuc`, a utility similar to coreutils `cut`, but more powerful. It allows to split text or bytes into parts and reassemble them in any order. I always found `cut` very practical for some tasks where `sed` or `awk` were overkill or awkward to use, but I also felt the need for more features. Some key differences from `cut`: - parts can be referenced by negative indexes - delimiters can be any number of characters long, or match a regex - can split text into lines, and reassemble them

  • Pypipe – A Python command-line tool for pipeline processing2023 · github.com · ▲213

    pypipe is a command-line tool for writing data pipelines in Python. When working with data processing in the terminal, I often find myself wanting to pass the output of commands to Python for further processing. In such cases, one can either write one-liners or create regular Python scripts and connect them through pipes. However, using pypipe makes this process more convenient and efficient.
