## What it is
sd is an intuitive find & replace command-line tool written in Rust, designed as a simpler, faster alternative to sed. It uses familiar JavaScript/Python-style regex syntax, offers a string-literal mode, and is significantly faster than sed on large files.

## Use cases
- find and replace text in files from the command line
- replace text across multiple lines in a file
- batch replace strings in large files quickly
- extract substrings using regex capture groups
- do in-place text substitution without sed quirks
- find and replace literal strings without escaping special characters

## When to choose
- you want simpler, more readable find & replace syntax than sed
- you need fast text replacement on very large files
- you prefer JavaScript/Python-style regex over sed's quirks
- you need multi-line (across-line) replacements
- you want painless in-place file editing from the terminal

## When to avoid
- you need sed's full scripting capabilities like line addressing or holding buffers
- you are in an environment where installing Rust-based tools is not possible
- you need a POSIX-standard tool guaranteed on every Unix system
- your workflow already depends heavily on sed scripts
