The rlpr package makes it possible (or at the very least, easier) to print files on remote sites to your local printer. It includes BSD-compatible replacements for `lpr', `lpq', and `lprm', whose functionality is a superset of their BSD counterparts. In other words, with the rlpr package, you can do everything you could do with the BSD printing commands, and more. The programs are all smaller, cleaner, and more portable than their BSD equivalents, and supported on just about any POSIX.1 system.
romfser is userland program for listing, extracting, and partially mangling romfs images. You can provide it with an offset in an image where the file system starts. The mangling ability is expressed in file substitution, where the new file has to be equal or smaller in size compared to the file being replaced. It can extract single files into the current directory or extract the whole filesystem while preserving the directory structure.
rospell is a UTF-8 text editor for programmers and general use. It features syntax highlighting, a code beautifier for C and C++, and support for gdb, ctags, grep, diff, and merge. It includes spellers for English, French, German, Spanish, and Romanian languages. Romanian aspell and hunspell dictionaries are also available.
rr is a basic command-line utility designed to retain/recall file and directory paths. This is done by treating the filename itself as a unique key to be referenced for future rr program calls. The purpose of this is to assist the user in shorthand typing and/or not having to remember arbitrary full paths. So, for example, "/etc/httpd/conf/httpd.conf" can be referenced as "// httpd.conf" in daily operations.
rsyncbackup is a handy tool for scheduled backups using rsync. rsyncbackup lets you easily setup multiple source folders and destinations, both locally, on your iPod or external firewire disk, or at a remote destination using ssh. rsyncbackup has no GUI, but is based on editing configuration files. The script is meant to be run in a crontab, so user interaction is not neccesary. Basic terminal skills are required to use the program.
Rsyslog is an enhanced multi-threaded syslogd. Among others, it offers support for on-demand disk buffering, reliable syslog over TCP, SSL, TLS, and RELP, writing to databases (MySQL, PostgreSQL, Oracle, and many more), email alerting, fully configurable output formats (including high-precision timestamps), the ability to filter on any part of the syslog message, on-the-wire message compression, and the ability to convert text files to syslog. It is a drop-in replacement for stock syslogd and able to work with the same configuration file syntax.
