history

Project history and usage

Tofrodos is a small command-line text conversion package for moving files between DOS/Windows CRLF line endings and Unix LF line endings.

Project history

The upstream README describes Tofrodos as two programs, fromdos and todos, that convert ASCII and UTF-8 text files between DOS and Unix newline formats. It is intentionally portable across Unix-like systems, Windows consoles, and DOS-family environments.

The package keeps the older Unix utility convention of behavior-by-command-name: the same program can be installed or renamed as fromdos, todos, dos2unix, or unix2dos, and it chooses the conversion direction from the invoked name.

Adoption history

The upstream documentation points Linux users to distribution repositories, and the package record shows it available through Homebrew, Debian, Ubuntu, and Fedora/DNF.

How it is used

Typical use is direct shell conversion of one or more text files, wildcard batches, or pipeline use such as converting output before comparing it with diff.

Why package nerds care

Tofrodos matters as a tiny packaging-era compatibility utility: it solves the recurring CRLF/LF problem without pulling in a larger editor or VCS workflow, and its fromdos/todos command names are easy to script.

Timeline

Current: Distributed as fromdos and todos for DOS-to-Unix and Unix-to-DOS newline conversion.
Current: Packaged by Homebrew, Debian, Ubuntu, and Fedora/DNF according to the input package-manager facts.

Related projects

dos2unix and unix2dos are related command names and behaviors explicitly supported by Tofrodos.
The package belongs to the same niche as other newline-normalization tools used in cross-platform source trees.
