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
