gnu-sed

brew install gnu-sed v4.10 GPL-3.0-or-later

GNU sed 4.10: stream editor for filtering and transforming text, with extended regex and in-place editing.

Why you might care

macOS ships with BSD sed, which lacks GNU extensions like `-i` with backup, `\L`/`\U` case conversion, and more regex features. Use gnu-sed if your scripts require GNU-specific behavior or you want cross-platform sed compatibility. It's a drop-in replacement installable as `gsed` to avoid shadowing the system binary.

Caveats

GNU "sed" has been installed as "gsed".
If you need to use it as "sed", you can add a "gnubin" directory
to your PATH from your bashrc like:

    PATH="$HOMEBREW_PREFIX/opt/gnu-sed/libexec/gnubin:$PATH"
