Painless regular expressions.   sd uses regex syntax that you already know from JavaScript and Python. Forget about dealing with quirks of sed or awk - get productive immediately.

String-literal mode.   Non-regex find & replace. No more backslashes or remembering which characters are special and need to be escaped.

Easy to read, easy to write.   Find & replace expressions are split up, which makes them easy to read and write. No more messing with unclosed and escaped slashes.

Smart, common-sense defaults.   Defaults follow common sense and are tailored for typical daily use.
