GNU Dico implements a flexible dictionary server and client according to RFC 2229 (DICT Server). It is able to access any database available, regardless of format, thanks to its modular structure. New modules may be written in C, Guile or Python. Dico also includes a command-line client, which may be used to query remote dictionary databases.

Translate Shell (formerly Google Translate CLI) is a command-line translator powered by Google Translate (default), Bing Translator, Yandex.Translate and Apertium. It gives you easy access to one of these translation engines from your terminal.

CMUdict (the Carnegie Mellon Pronouncing Dictionary) is a free pronouncing dictionary of English, suitable for uses in speech technology and is maintained by the Speech Group in the School of Computer Science at Carnegie Mellon University.

This package provides SKK-JISYO.L, the standard dictionary file for SKK Japanese input systems, and various dictionary files. SKK-JISYO.L can be used with emacs-ddskk or uim package.

Diffoscope tries to get to the bottom of what makes files or directories different. It recursively unpacks archives of many kinds and transforms various binary formats into more human readable forms to compare them. It can compare two tarballs, ISO images, or PDFs just as easily.

Diffoscope has many optional dependencies; diffoscope --list-missing-tools guix will display optional packages to install.

Reprotest builds the same source code twice in different environments, and then checks the binaries produced by each build for differences. If any are found, then diffoscope or diff is used to display them in detail for later analysis.

This is a client for the remote diffoscope service.

Diffoscope tries to get to the bottom of what makes files or directories different. It recursively unpacks archives of many kinds and transforms various binary formats into more human readable forms to compare them. It can compare two tarballs, ISO images, or PDFs just as easily.

Results are displayed by default, stored as local text or html files, or made available via a URL on https://try.diffoscope.org. Results stored on the server are purged after 30 days.

This Python package implements Ted Dunning's t-digest data structure, which is designed around computing accurate estimates such as percentiles, quantiles and trimmed means from streaming or distributed data. Two t-digests can be added, making the data structure ideal for map-reduce settings, and can be serialized into much less than 10 kB, instead of storing the entire list of data.

xxHash is an extremely fast non-cryptographic hash algorithm. It works at speeds close to RAM limits, and comes in both 32- and 64-bit flavours. The code is highly portable, and hashes of the same length are identical on all platforms (both big and little endian).

This package provides Python bindings for the xxHash hash algorithm.

This package provides a portable hash function and random number generator suitable for use in data structures. Provided by default in Zig, V, and Nim programming language standard libraries.

udevil is a command line program that mounts and unmounts removable devices without a password, shows device info, and monitors device changes. It can also mount ISO files, NFS, SMB, FTP, SSH and WebDAV URLs, and tmpfs/ramfs filesystems.

This package provides a tool to resize FAT partitions using libparted.

Wipe can erase files and block devices securely. To work properly it relies on several assumptions like having the block device write the correct sectors, etc. For files it also doesn't work on log-structured file systems such as F2FS, JFFS, LogFS, etc. You should not trust wipe to work as advertised until you have manually verified that all its assumption hold true on your system. To overwrite data it uses the Mersenne Twister pseudo-random number generator (PRNG) that is seeded with /dev/urandom or, if unavailable, /dev/random.

TestDisk is primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms were caused by faulty software or human error (such as accidentally deleting a partition table). TestDisk can:

1. Fix partition table, recover deleted partition

2. Recover FAT32 boot sector from its backup

3. Rebuild FAT12/FAT16/FAT32 boot sector

4. Fix FAT tables

5. Rebuild NTFS boot sector

6. Recover NTFS boot sector from its backup

7. Fix MFT using MFT mirror

8. Locate ext2/ext3/ext4 Backup SuperBlock

9. Un-delete files from FAT, exFAT, NTFS and ext2 file systems

10. Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.

This package also includes the photorec command, described below.

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted. It can recover lost files from at least:

1. FAT

2. NTFS

3. exFAT

4. ext2/ext3/ext4 file system

5. HFS+

XFE (X File Explorer) is a file manager for X. It is based on the popular but discontinued, X Win Commander. It aims to be the file manager of choice for all light thinking Unix addicts!

F3 (Fight Flash Fraud or Fight Fake Flash) tests the full capacity of a flash card (flash drive, flash disk, pendrive). F3 writes to the card and then checks if can read it. It will assure you haven't been sold a card with a smaller capacity than stated.

nwipe securely erases disks using a variety of methods to ensure the data cannot be recovered. It can wipe multiple drives in parallel and can be used noninteractively or with a text-based user interface.

Gdu is a disk usage analyzer written in Go. It is intended primarily for SSD disks where it can fully utilize parallel processing, but it also works on HDDs.

This software supports RAID device discovery, RAID set activation, creation, removal, rebuild and display of properties for ATARAID/DDF1 metadata.

dmraid uses libdevmapper and the device-mapper kernel runtime to create devices with respective mappings for the ATARAID sets discovered.

The Open iSCSI project is a high-performance, transport independent, multi-platform implementation of RFC3720 iSCSI.

Features:

• highly optimized and very small-footprint data path

• persistent configuration database

• SendTargets discovery

• provides CHAP support

• PDU header Digest

• multiple sessions

rmlint finds space waste and other broken things on your file system and offers to remove it. rmlint can find:

• duplicate files and duplicate directories,

• non-stripped binaries (i.e. binaries with debug symbols),

• broken symbolic links,

• empty files and directories,

• files with broken user and/or group ID.

Duc maintains a database of accumulated sizes of directories of the file system, and allows you to query this database with some tools, or create fancy graphs showing you where your bytes are.

Duc comes with console utilities, ncurses and X11 user interfaces and a CGI wrapper for disk usage querying and visualisation.

GNU Parted is a package for creating and manipulating disk partition tables. It includes a library and command-line utility.
