GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disk, CD-ROM, etc.) to another, trying to rescue the good parts first in case of read errors. GNU ddrescuelog is a tool that manipulates ddrescue logfiles, shows logfile contents, converts logfiles to/from other formats, compares logfiles, tests rescue status, and can delete a logfile if the rescue is done.
GNU ed is an 8-bit clean implementation of the POSIX line-oriented text editor. Ed is the "standard" text editor in the sense that it is the original editor for Unix, and thus widely available. For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.
Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving. Lzip is a clean implementation of the LZMA algorithm. The Lzip file format is designed for long-term data archiving. It is clean, provides very safe four factor integrity checking, and is backed by the recovery capabilities of lziprecover.
KDE-Services extends the features of the Dolphin File Manager right-click menu in the KDE graphical environment. It allows you to play and convert between several video formats, extract audio from movies and convert them to MP3 or FLAC, convert audio to MP3 or FLAC, securely send a file or directory to Mailx as an email, send files to Thunderbird as attachments, burn and checksum ISO images, execute scripts and applications, get low-level information on video files, build ISO images from folders, replace text, search, SSH, use Midnight Commander, use system, network, and backup/restore tools, use Samba, extract subtitles from MKV video, multiplex subtitles into MPEG-2 videos, and work with YouTube, DVDs, multimedia, GPG. You can add a timestamp prefix to a filename or directory name. A paranoid shredder, an HTTP publisher, graphic tools, RPM package tools, Xorg configuration, and Dropbox tools are included.
Zutils is a collection of utilities able to deal with any combination of compressed and uncompressed files transparently. If any given file, including standard input, is compressed, its decompressed content is used. Compressed files are decompressed on the fly; no temporary files are created. These utilities are not wrapper scripts but safer and more efficient C++ programs. In particular the "--recursive" option is very efficient in those utilities supporting it. The provided utilities are zcat, zcmp, zdiff, zgrep, ztest, and zupdate. The supported formats are bzip2, gzip, lzip, and xz. The compressor to be used for each format is configurable at runtime.
Lbzip2 is a parallel, SMP-based, bzip2-compatible compression utility, with a commandline resembling that of the original bzip2. It is usable both on its own and as a filter passed to GNU tar with the "--use-compress-program" option. It uses Gnulib, and its building and testing process is managed by the GNU build system. Starting with release 2.0, lbzip2 is independent of libbz2 and features yambi, an independent BWT compression stack with improved speed and robustness.
GNU Moe is a powerful, 8-bit clean console text editor for ISO-8859 and ASCII character encodings. It has a modeless, user-friendly interface, online help, multiple windows, unlimited undo/redo capability, unlimited line length, global search/replace (on all buffers at once), block operations, automatic indentation, word wrapping, filename completion, a directory browser, duplicate removal from prompt histories, and delimiter matching.
Clzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Clzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving. Clzip uses the lzip file format; the files produced by clzip are fully compatible with lzip-1.4 or newer, and can be rescued with lziprecover. Clzip is, in fact, a C language implementation of lzip, intended for embedded devices or systems lacking a C++ compiler. The lzip file format is designed for long-term data archiving and provides very safe integrity checking.
The OATH Toolkit makes it easy to build one-time password authentication systems. It contains shared libraries, commandline tools, and a PAM module. Supported technologies include the event-based HOTP algorithm (RFC4226) and the time-based TOTP algorithm (RFC6238). OATH stands for Open AuTHentication, which is the organization which specifies the algorithms. For managing secret key files, the Portable Symmetric Key Container (PSKC) format described in RFC6030 is supported.
