sdcv is simple text-based utility for work with dictionaries in StarDict's format.

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.

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.

This package provides Python bindings for the xxHash hash algorithm.

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).

ranger is a console file manager with Vi key bindings. It provides a minimalistic and nice curses interface with a view on the directory hierarchy. It ships with rifle, a file launcher that is good at automatically finding out which program to use for what file type.

hdparm is a command-line utility to control ATA controllers and disk drives. It can increase performance and/or reliability by careful tuning of hardware settings like power and acoustic management, DMA modes, and caching. It can also display detailed device information, or be used as a simple performance benchmarking tool.

hdparm provides a command line interface to various Linux kernel interfaces provided by the SATA/ATA/SAS libata subsystem, and the older IDE driver subsystem. Many external USB drive enclosures with SCSI-ATA Command Translation (SAT) are also supported.

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

fff (fast file-manager) is a simple, blazing fast and minimal file manager for Linux, written in bash. It only requires bash and coreutils, and its highly optimized now for efficient performance.

This package provides a user-extensible heap manager built on top of jemalloc which enables control of memory characteristics and a partitioning of the heap between kinds of memory (for NUMA).

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+

Gpart tries to guess the partitions on a PC-style, MBR-partitioned disk after they have been inadvertently deleted or the primary partition table at sector 0 damaged. In both cases, the contents of these partitions still exist on the disk but the operating system cannot access them.

Gpart ignores the partition table and scans each sector of the device or image file for several known file system and partition types. Only partitions which have been formatted in some way can be recognized. Several file system guessing modules are built in; more can be written and loaded at run time.

The guessed table can be restored manually, for example with fdisk, written to a file, or---if you firmly believe it's entirely correct---directly to disk.

It should be stressed that gpart does a very heuristic job. It can easily be right in its guesswork but it can also be terribly wrong. Never believe its output without any plausibility checks.

The dosfstools package includes the mkfs.fat and fsck.fat utilities, which respectively make and check MS-DOS FAT file systems.

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!

QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up.

Duperemove is a simple tool for finding duplicated extents and submitting them for deduplication. When given a list of files it will hash their contents on a block by block basis and compare those hashes to each other, finding and categorizing blocks that match each other. When given the -d option, duperemove will submit those extents for deduplication using the Linux kernel extent-same ioctl.

Duperemove can store the hashes it computes in a hash file. If given an existing hash file, duperemove will only compute hashes for those files which have changed since the last run. Thus you can run duperemove repeatedly on your data as it changes, without having to re-checksum unchanged data.

Duperemove can also take input from the fdupes program.

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.

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.

Sdparm reads and modifies SCSI device parameters. These devices can be SCSI disks, in which case the role of sdparm is similar to its namesake: the hdparm utility originally designed for ATA disks. However, sdparm can be used to access parameters on any device that uses a SCSI command set. Such devices include CD/DVD drives (irrespective of transport), SCSI and ATAPI tape drives, and SCSI enclosures. This utility can also send commands associated with starting and stopping the media, loading and unloading removable media and some other housekeeping functions.

This package provides a statically-linked fsck.fat and a fsck.vfat compatibility symlink for use in an initrd.

This package provides a partial implementation of iSNS, specified by RFC4171. It's an maintained fork of https://github.com/cleech/open-isns.
