udftools is a set of programs for reading and modifying UDF file systems. UDF is a file system mostly used for DVDs and other optical media. It supports read-only media (DVD/CD-R) and rewritable media that wears out (DVD/CD-RW).

OpenZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the OpenZFS community.

This package provides the user space component of CacheFiles, a caching back end that uses a directory on a locally mounted file system (such as ext4) as a cache to speed up (by reducing) access to a slower file system and make it appear more reliable.

The cached file system is often a network file system such as NFS or CIFS, but can also be a local file system like ISO 9660 on a slow optical drive.

CacheFiles itself is part of the kernel but relies on this user space cachefilesd daemon to perform maintenance tasks like culling and reaping stale nodes. Only one such daemon can be running at a time, and communicates with the kernel through the /dev/cachefiles character device.

This version modifies David Howells original cachefilesd---which appears unmaintained---to use the inotify API instead of the deprecated dnotify to monitor file changes.

bindfs is a FUSE file system for mounting a directory to another location, similar to mount --bind. It can be used for:

• Making a directory read-only.

• Making all executables non-executable.

• Sharing a directory with a list of users (or groups).

• Modifying permission bits using rules with chmod-like syntax.

• Changing the permissions with which files are created.

mergerfs-tools is a suite of programs that can audit permissions and ownership of files and directories on a mergerfs volume, duplicates files and directories across branches in its pool, find and remove duplicate files, balance pool drives, consolidate files in a single mergerfs directory onto a single drive and create FreeDesktop.org Trash specification compatible directories.

Squashfuse lets you mount SquashFS archives in user-space. It supports almost all features of the SquashFS format, yet is still fast and memory-efficient.

This package provides statically-linked jfs_fsck command taken from the jfsutils package. It is meant to be used in initrds.

fscryptctl is a low-level tool written in C that handles raw keys and manages policies for Linux filesystem encryption, specifically the fscrypt kernel interface which is supported by the ext4, f2fs, UBIFS, and CephFS filesystems.

TMSU is a tool for tagging your files. It provides a simple command-line utility for applying tags and a virtual file system to give you a tag-based view of your files from any other program. TMSU does not alter your files in any way: they remain unchanged on disk, or on the network, wherever your put them. TMSU maintains its own database and you simply gain an additional view, which you can mount where you like, based upon the tags you set up.

This package provides the bcachefs command-line tool with many subcommands for creating, checking, and otherwise managing bcachefs file systems. Traditional aliases like mkfs.bcachefs are also included.

Bcachefs is a CoW file system supporting native encryption, compression, snapshots, and (meta)data checksums. It can use multiple block devices for replication and/or performance, similar to RAID.

In addition, bcachefs provides all the functionality of bcache, a block-layer caching system, and lets you assign different roles to each device based on its performance and other characteristics.

Autofs is a kernel-based automounter for use with the Linux autofs4 module. It automatically mounts selected file systems when they are used and unmounts them after a set period of inactivity. This provides centrally-managed, consistent file names for users and applications, even in a large and/or frequently changing (network) environment.

DwarFS is a read-only file system with a focus on achieving very high compression ratios in particular for very redundant data.

DwarFS also doesn't compromise on speed and for some cases it is on par with or performs better than SquashFS. For the primary use case, DwarFS compression is an order of magnitude better than SquashFS compression, it's 6 times faster to build the file system, it's typically faster to access files on DwarFS and it uses less CPU resources.

Distinct features of DwarFS are:

• Clustering of files by similarity using a similarity hash function. This makes it easier to exploit the redundancy across file boundaries.

• Segmentation analysis across file system blocks in order to reduce the size of the uncompressed file system. This saves memory when using the compressed file system and thus potentially allows for higher cache hit rates as more data can be kept in the cache.

• Highly multi-threaded implementation. Both the file system creation tool as well as the FUSE driver are able to make good use of the many cores of your system.

• Optional experimental Python scripting support to provide custom filtering and ordering functionality.

These are command-line user space tools for the exFAT file systems. Included are mkfs.exfat to create (format) new exFAT file systems, and fsck.exfat to check their consistency and repair them.

This package provides Snapper, a tool that helps with managing snapshots of Btrfs subvolumes and thin-provisioned LVM volumes. It can create and compare snapshots, revert differences between them, and supports automatic snapshots timelines.

The JFSutils are a collection of utilities for managing the JFS, a 64-bit journaling file system created by IBM and later ported to the kernel Linux. The following commands are available:

1. fsck.jfs: check and repair a JFS file system or replay its transaction log.

2. logdump: dump the JFS journal log.

3. logredo: replay the JFS journal log.

4. mkfs.jfs: create a new JFS file system.

5. xchklog: save a JFS fsck log to a file.

6. xchkdmp: dump the contents of such a log file.

7. xpeek: a JFS file system editor with a shell-like interface.

Gocryptfs is an encrypted overlay filesystem written in Go. It features a file-based encryption that is implemented as a mountable FUSE filesystem.

Gocryptfs was inspired by EncFS and strives to fix its security issues while providing good performance. Gocryptfs is as fast as EncFS in the default mode and significantly faster than paranoia mode in EncFS, which provides a security level comparable to Gocryptfs.

On CPUs without AES-NI, gocryptfs uses OpenSSL through a thin wrapper called stupidgcm. This provides a 4x speedup compared to Go's builtin AES-GCM implementation.

httpfs2 is a fuse file system for mounting any HyperText (HTTP or HTTPS) URL. It uses HTTP/1.1 byte ranges to request arbitrary bytes from the web server, without needing to download the entire file. This is particularly useful with large archives such as ZIP files and ISO images when you only need to inspect their contents or extract specific files. Since the HTTP protocol itself has no notion of directories, only a single file can be mounted.

fscrypt is a high-level tool for the management of Linux native filesystem encryption. It manages metadata, key generation, key wrapping, PAM integration, and provides a uniform interface for creating and modifying encrypted directories.

This package provides the statically-linked bcachefs from a minimal bcachefs-tools package. It is meant to be used in initrds.

RewriteFS is a FUSE to change the name of accessed files on the fly based on any number of regular expressions. It's like the rewrite action of many Web servers, but for your file system. For example, it can help keep your home directory tidy by transparently rewriting the location of configuration files of software that doesn't follow the XDG directory specification from ~/.name to ~/.config/name.

GPhotoFS is a FUSE file system module to mount your camera as a file system on Linux. This allow using your camera with any tool able to read from a mounted file system.

The file command is a file type guesser, a command-line tool that tells you in words what kind of data a file contains. It does not rely on filename extensions to tell you the type of a file, but looks at the actual contents of the file. This package provides the libmagic library.

The command-line interface for the hledger accounting system. Its basic function is to read a plain text file describing financial transactions and produce useful reports.

hledger is a robust, cross-platform set of tools for tracking money, time, or any other commodity, using double-entry accounting and a simple, editable file format, with command-line, terminal and web interfaces. It is a Haskell rewrite of Ledger, and one of the leading implementations of Plain Text Accounting.

GBonds is a U.S. Savings Bond inventory program for the GNOME desktop environment. It allows you to track the current redemption value and performance of your U.S. Savings Bonds and keep a valuable record of the bonds you own.
