R is a language and environment for statistical computing and graphics. It provides a variety of statistical techniques, such as linear and nonlinear modeling, classical statistical tests, time-series analysis, classification and clustering. It also provides robust support for producing publication-quality data plots. A large amount of 3rd-party packages are available, greatly increasing its breadth and scope.

rw computes rank-width and rank-decompositions of graphs.

This is a reimplementation by Byron Rakitzis of the Plan 9 shell. It has a small feature set similar to a traditional Bourne shell.

rr is a lightweight tool for recording, replaying and debugging execution of applications (trees of processes and threads). Debugging extends GDB with very efficient reverse-execution, which in combination with standard GDB/x86 features like hardware data watchpoints, makes debugging much more fun.

The file manager that is not ranger.

RTV provides a text-based interface to view and interact with Reddit.

The RPI is a lightweight framework to encapsulate image registration algorithms.

Run is a tool to easily manage and invoke small scripts and wrappers by using a Runfile.

Rct is a set of C++ tools that provide nicer (more Qt-like) APIs on top of Standard Template Library (STL) classes.

The GNU/Linux distribution, a set of tools for managing development environments, home environments, and operating systems, a set of predefined configurations, practices and workflows.

RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl and Python. It is a C++ library.

rex runs a supplied command or shell script on several hosts in succession or in parallel. It can also be used to copy a file or files to several hosts.

Ruy is a matrix multiplication library. Its focus is to cover the matrix multiplication needs of neural network inference engines. Its initial user has been TensorFlow Lite, where it is used by default on the ARM CPU architecture.

RCS is the original Revision Control System. It works on a file-by-file basis, in contrast to subsequent version control systems such as CVS, Subversion, and Git. This can make it suitable for system administration files, for example, which are often inherently local to one machine.

The RPM Package Manager (RPM) is a command-line driven package management system capable of installing, uninstalling, verifying, querying, and updating computer software packages. Each software package consists of an archive of files along with information about the package like its version, a description. There is also a library permitting developers to manage such transactions from C or Python.

Set of OpenPGP (RFC4880) tools that works on Linux, *BSD and macOS as a replacement of GnuPG. It is maintained by Ribose after being forked from NetPGP, itself originally written for NetBSD.

librnp is the library used by rnp for all OpenPGP functions, useful for developers to build against. It is a “real” library, not a wrapper like GPGME of GnuPG.

RIG (Random Identity Generator) generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself. Also, if the Web site/BBS/person you are giving the information to tries to cross-check the city, state, zip, or area code, it will check out.

This package is an unofficial command line client for Bitwarden. Although Bitwarden ships with a command line client, but it's limited by being stateless, which makes it very difficult to use. This client avoids that problem by maintaining a background process which is able to hold the keys in memory, similar to the way that ssh-agent or gpg-agent work. This allows the client to be used in a much simpler way, with the background agent taking care of maintaining the necessary state.

The rcm suite of tools is for managing dotfiles directories. This is a directory containing all the .*rc files in your home directory (.zshrc, .vimrc, and so on). These files have gone by many names in history, such as “rc files” because they typically end in rc or “dotfiles” because they begin with a period. This suite is useful for committing your rc files to a central repository to share, but it also scales to a more complex situation such as multiple source directories shared between computers with some host-specific or task-specific files.

Various utilities for the Multiplicative Multinomial distribution.

This package provides a programmatic interface to the Request Tracker (RT) HTTP API <https://rt-wiki.bestpractical.com/wiki/REST>. RT is a popular ticket tracking system.
