The Linux kernel documentation describes SquashFS as a compressed read-only filesystem for Linux intended for archival use and constrained block-device or memory systems. ### Adoption history The official kernel documentation says squashfs-tools is very likely packaged by Linux distributions, and the project README includes packaging-status material. The input package-manager facts list Homebrew and zypper for this formula. ### How it is used The main commands are mksquashfs for building images and unsquashfs for extracting or listing them, with newer sqfstar and sqfscat commands supporting tar-style and cat-style workflows. Recent releases emphasize reproducible images, parallel reading, streaming output, and richer help/man-page coverage. ### Why package nerds care Package nerds care because SquashFS images are common in live systems, appliance-style images, containers, firmware, and compressed software payloads. The tools are the boring but essential bridge between package contents and a compact read-only filesystem artifact. ### Timeline - 2002: Squashfs-tools 1.0 initial release. - 2006: 3.0 and 3.1 releases added major filesystem and tools improvements. - 2009: 4.0 release introduced major filesystem improvements. - 2023: 4.6 release improved xattrs, pseudo files, and conversion workflows. - 2025: 4.7 release added parallel file reading and reproducible-image improvements. - 2026: 4.7.5 bug-fix release published. ### Related projects - Linux SquashFS kernel driver, cramfs, initramfs/live media build systems, mksquashfs, unsquashfs, sqfstar, sqfscat. ### Sources - - - - - - source_facts.package-manager ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** squashfs - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - zypper - squashfs - 4.6.1-2.8: normalized package name match | openSUSE Tumbleweed package metadata: squashfs from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | A Read-Only File System with Efficient Compression | https://github.com/plougher/squashfs-tools ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Archive and compression packages](https://www.automicvault.com/pkg/archive-compression-tools/) - Matched archive or compression metadata. - [lz4](https://www.automicvault.com/pkg/brew/lz4/) - Runtime dependency declared by Homebrew. - [xz](https://www.automicvault.com/pkg/brew/xz/) - Runtime dependency declared by Homebrew. - [zstd](https://www.automicvault.com/pkg/brew/zstd/) - Runtime dependency declared by Homebrew. - [gnu-sed](https://www.automicvault.com/pkg/brew/gnu-sed/) - Build dependency declared by Homebrew. - [help2man](https://www.automicvault.com/pkg/brew/help2man/) - Build dependency declared by Homebrew. - [apptainer](https://www.automicvault.com/pkg/brew/apptainer/) - Popular package that depends on this formula. - [snap](https://www.automicvault.com/pkg/brew/snap/) - Popular package that depends on this formula. - [squashfuse](https://www.automicvault.com/pkg/brew/squashfuse/) - Popular package that depends on this formula. - [dwarfs](https://www.automicvault.com/pkg/brew/dwarfs/) - Shares av.db curated category or tags: cli, compression, filesystem, filesystems, system. - [btrfs-progs](https://www.automicvault.com/pkg/brew/btrfs-progs/) - Shares av.db curated category or tags: cli, filesystem, filesystems, linux, system. - [clzip](https://www.automicvault.com/pkg/brew/clzip/) - Shares av.db curated category or tags: archive, cli, compression, system. - [dysk](https://www.automicvault.com/pkg/brew/dysk/) - Shares av.db curated category or tags: cli, filesystem, filesystems, linux, system. - [e2fsprogs](https://www.automicvault.com/pkg/brew/e2fsprogs/) - Shares av.db curated category or tags: cli, filesystem, filesystems, linux, system. - [erofs-utils](https://www.automicvault.com/pkg/brew/erofs-utils/) - Shares av.db curated category or tags: cli, filesystem, filesystems, linux, system. - [gzip](https://www.automicvault.com/pkg/brew/gzip/) - Shares av.db curated category or tags: archive, cli, compression, system. - [lunzip](https://www.automicvault.com/pkg/brew/lunzip/) - Shares av.db curated category or tags: archive, cli, compression, system. - [ext4fuse](https://www.automicvault.com/pkg/brew/ext4fuse/) - Local package facts share a topical domain.
