BW whois is a modern whois client that works as a full-featured Web application or as a commandline tool.

cdctl is a program similar to eject. Like eject, it can eject your CD-ROM/DVD drive, but it does a whole lot more. Cdctl provides a user interface to the 2.2 kernel's uniform cdrom driver's ioctl calls, and most 2.0 cdrom drivers (ide-cd and scsi). Cdctl is also capable of doing everything a regular console cd player can as well as drive capability interrogation, autoeject setting, maximum/mininum speed cap setting, disc-changer disc selection, disc status readback, MCN querying, table of contents header readback, track header readback, and much more.
ColdSync is a portable synchronization tool for Palm devices (PalmPilot, Handspring Visor, etc.) that runs under *BSD, Solaris, Digital Unix/Tru64, Linux, AIX, and Windows NT. It supports PalmOS 2.0 (original PalmPilot) and later. It is only known to support Visor syncing under FreeBSD and Linux, however. It supports IR syncing under Linux. ColdSync can back up, restore, install, and synchronize database, and can be extended and customized through the use of conduits. ColdSync is rather paranoid and takes pains not to delete anything it isn't 100% sure about.
ctrlxmms is a small Perl script designed to increase the useability of XMMS. With it, you can use most of the common GUI functions of XMMS from the CLI. You also have a few handy commands which are not available from the GUI. Together with lirc and a remote (eg. Anir Multimedia Magic), this is a wonderful tool.
lphdisk is a Linux utility to prepare hibernation partitions for use on laptops with Phoenix NoteBIOS. This utility is not needed to use the Suspend-To-Disk feature. It allows one to create a valid hibernation partition without having to boot to DOS and use the buggy PHDISK.EXE utility. This is especially useful after resizing/moving partitions or drives, or after adding system RAM to a laptop.
mp3frip renames MP3 files. It features searching directories recursively, upper, lower or title case files, changing underscores to spaces and vice versa, ability to form file names from ID3v1(.1) tag (artist, song title, album, track number) if they exist and the existing file name, Test mode, Smart/Stoopid/Safer mode (won't overwrite existing files), and more.
