## What it is
A curated collection of useful sed one-liners, patterns, and a short tutorial for daily text-processing tasks on the command line. It is a reference document (README) rather than runnable software.

## Use cases
- learn sed one-liners for text substitution
- find a sed command to delete empty lines
- replace text on specific lines or line ranges with sed
- print lines between two regex matches
- reference for sed custom delimiters when working with paths
- quick sed tutorial for daily linux usage

## When to choose
- you need quick, practical sed snippets with short explanations
- you want a free cheatsheet covering common text-processing tasks
- you are learning or teaching command-line text manipulation

## When to avoid
- you need a tool or library to embed in your application
- you need comprehensive awk or grep coverage (see dedicated guides)
- you need structured documentation with versioned releases or a license

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: developer-tools, tutorials
- platform: cli
- tags: sed, cheatsheet, text-processing, one-liners, unix, regex, command-line, linux, macos
