ascii lists ASCII idiomatic names and octal/decimal code-point forms. It provides easy conversion between various byte representations and the American Standard Code for Information Interchange (ASCII) character table. It knows about a wide variety of hex, binary, octal, Teletype mnemonic, ISO/ECMA code point, slang names, XML entity names, and other representations. Given any one on the command line, it will try to display all others. Called with no arguments, it displays a small, handy ASCII chart.
asmutils is a set of miscellaneous utilities written in assembly language, targeted on embedded systems and small distributions (e.g. installation or rescue disks). It also contains a small libc and a crypto library. It is optimized for size, memory usage, and speed, and offers fairly good functionality. The project supports Linux and the BSD family. Unixware, Solaris, and AtheOS support is in beta stage. This package also aims to provide a portable development framework, and to encourage assembly programmers to write for Linux/Unix.
beep does what you'd expect: it beeps. But unlike printf("\a"), beep allows you to control pitch, duration, and repetitions. Its job is to live inside shell/perl scripts and allow more granularity than one has otherwise. It is controlled completely through command line options. It's not supposed to be complex, and it isn't - but it makes system monitoring (or whatever else it gets hacked onto) that much more informative.
Boxes is a text filter that can draw any kind of box around its input text. Box design choices range from simple boxes to complex ASCII art. A box can also be removed and repaired, even if it has been badly damaged by editing of the text inside. Since the generated boxes may be open on any side, the program can also be used to create regional comments in any programming language. New box designs of all sorts can easily be added and shared by appending to a free format configuration file. In addition to being a command line tool, Boxes integrates well with any text editor that supports filters.
breloc does binary edits on files to relocate compiled-in prefixes, padding with extra slashes to make up for differences in the length of the prefixes. In order for breloc to be most effective, a binary package should be configured with a prefix that has a lot of extra slashes at the end of it. beloc is distributed as part of the nsbd package, but it is also quite useful independently.
The BRU Backup and Restore Utility features data-verified backups, scalability, configurability, and ease of use for Linux and Unix. Versions are available for Linux, FreeBSD, and most UNIX variants. It works via an X11 interface, command line interactive, or through a scripted, scheduled (CRON) mechanism.
