history
Project history and usage
Squashfs-tools provides the user-space tools for creating, extracting, listing, and converting SquashFS compressed read-only filesystems.
Project history
The Squashfs-tools changelog records an initial 1.0 release in 2002 and a 4.0 release in April 2009 with major filesystem improvements. 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.
