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. ### Sources - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** tofrodos - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - tofrodos - 1.7.13+ds-6: normalized package name match | Debian stable package indexes: tofrodos from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Converts DOS <-> Unix text files, alias tofromdos | https://www.thefreecountry.com/tofrodos/index.shtml - Ubuntu apt - tofrodos - 1.7.13+ds-6: normalized package name match | Ubuntu 24.04 LTS package indexes: tofrodos from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Converts DOS <-> Unix text files, alias tofromdos | https://www.thefreecountry.com/tofrodos/index.shtml - dnf - tofrodos - 1.7.13-27.fc43: normalized package name match | Fedora Rawhide package metadata: tofrodos from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Converts text files between MSDOS and Unix file formats | http://www.thefreecountry.com/tofrodos/ ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [dos2unix](https://www.automicvault.com/pkg/brew/dos2unix/) - Shares av.db curated category or tags: cli, developer-tools, dos, line-endings, text-conversion. - [gnu-sed](https://www.automicvault.com/pkg/brew/gnu-sed/) - Shares av.db curated category or tags: cli, developer-tools, text-processing, unix. - [minised](https://www.automicvault.com/pkg/brew/minised/) - Shares av.db curated category or tags: cli, developer-tools, text-processing, unix. - [opencc](https://www.automicvault.com/pkg/brew/opencc/) - Shares av.db curated category or tags: cli, developer-tools, text-conversion, text-processing. - [randomize-lines](https://www.automicvault.com/pkg/brew/randomize-lines/) - Shares av.db curated category or tags: cli, developer-tools, text-processing, unix. - [recode](https://www.automicvault.com/pkg/brew/recode/) - Shares av.db curated category or tags: cli, developer-tools, text-conversion, text-processing. - [tal](https://www.automicvault.com/pkg/brew/tal/) - Shares av.db curated category or tags: cli, developer-tools, line-endings, text-processing. - [vip](https://www.automicvault.com/pkg/brew/vip/) - Shares av.db curated category or tags: cli, developer-tools, text-processing, unix. - [txt2man](https://www.automicvault.com/pkg/brew/txt2man/) - Local package facts share a topical domain.
