GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disk, CD-ROM, etc.) to another, trying hard to rescue data 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.
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.
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.
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.
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.
GNU Recutils is a set of tools and libraries to access human-editable text-based databases called recfiles. A recfile contains data structured as a sequence of records. The rec format supports data integrity with the usage of record descriptors (keys, mandatory fields, field types, etc.) as well as the ability of record fields to refer to other records. Despite its simplicity, recfiles can be used to store medium-sized databases. The GNU recutils suite comprises a texinfo manual describing the Rec format, a C library (librec) providing a rich set of functions to access rec files, a set of C utilities that can be used in shell scripts and in the command line to operate on rec files, and an Emacs mode (rec-mode).
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.
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.
Plzip is a massively parallel (multi-threaded), lossless data compressor based on the lzlib compression library, with a user interface similar to the one of lzip, bzip2, or gzip. It can compress/decompress large files on multiprocessor machines much faster than lzip, at the cost of a slightly-reduced compression ratio. On files large enough (several GB), plzip can use hundreds of processors. On files of only a few MB, it is better to use lzip. Plzip uses the lzip file format, and the files produced by plzip are fully compatible with lzip-1.4 or newer, and can be rescued with lziprecover.
Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz) able to repair slightly damaged files, recover badly damaged files from two or more copies, extract data from damaged files, decompress files, and test integrity of files. Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip, and pdlzip. It makes lzip files resistant to bit-flip, one of the most common forms of data corruption, and its recovery capabilities contribute to make of the lzip format one of the best options for long-term data archiving.
