GitHub repository metadata records the public repository creation in December 2020. ### Adoption history The README advertises package-manager paths for AUR, Homebrew, Snap, Debian-style release packages, and source builds. The Homebrew input also records Alpine and Homebrew packaging, which fits a niche utility used by archive and compression users rather than a broad desktop audience. ### How it is used t2sz runs in tar mode for .tar input by default and raw mode for other files, accepts stdin and stdout, exposes compression-level and block-size controls, and produces output readable by ordinary Zstandard tools. Seeking benefits require companion readers such as libzstd-seek, indexed_zstd, or ratarmount. ### Why package nerds care Package nerds care because t2sz sits at the intersection of tar, zstd, random access, and archival ergonomics: it preserves standard decompression while adding structure that downstream tooling can exploit. ### Timeline - 2020: The public GitHub repository was created. - 2026: GitHub releases show v1.2.x releases, with v1.2.5 published on 2026-03-08. - 2026: The README documents Homebrew installation on Linux and macOS. ### Related projects - The README names zstd, libzstd-seek, indexed_zstd, and ratarmount as related projects for compression and seekable reading. ### Sources - - - - input.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:** t2sz - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - apk - t2sz - 1.1.2-r0: normalized package name match | Alpine Linux edge package indexes: t2sz from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | t2sz compress a file into a seekable zstd with special handling for tar archives. | https://github.com/martinellimarco/t2sz ## 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. - [zstd](https://www.automicvault.com/pkg/brew/zstd/) - Runtime dependency declared by Homebrew. - [cmake](https://www.automicvault.com/pkg/brew/cmake/) - Build dependency declared by Homebrew. - [atool](https://www.automicvault.com/pkg/brew/atool/) - Shares av.db curated category or tags: archives, cli, compression, system. - [ouch](https://www.automicvault.com/pkg/brew/ouch/) - Shares av.db curated category or tags: archives, cli, compression, system. - [ratarmount](https://www.automicvault.com/pkg/brew/ratarmount/) - Shares av.db curated category or tags: archives, cli, system, tar. - [tarlz](https://www.automicvault.com/pkg/brew/tarlz/) - Shares av.db curated category or tags: cli, compression, system, tar. - [cabextract](https://www.automicvault.com/pkg/brew/cabextract/) - Shares av.db curated category or tags: archives, cli, compression, system. - [clzip](https://www.automicvault.com/pkg/brew/clzip/) - Shares av.db curated category or tags: cli, compression, system. - [crabz](https://www.automicvault.com/pkg/brew/crabz/) - Shares av.db curated category or tags: cli, compression, system. - [dwarfs](https://www.automicvault.com/pkg/brew/dwarfs/) - Shares av.db curated category or tags: cli, compression, system. - [squashfs](https://www.automicvault.com/pkg/brew/squashfs/) - Local package facts share a topical domain.
