## プロジェクトの歴史と使われ方

GNU tar is the GNU archiving program for creating, listing, updating, and extracting tar archives. It is one of the package ecosystem's foundational tools because source releases, backups, and portable file bundles often travel as tar archives.

### プロジェクトの歴史

The GNU tar README says GNU tar is derived from John Gilmore's public-domain tar. The GNU tar manual credits John Gilmore as the original author, Jay Fenlason and Joy Kendall for GNU enhancements, and later maintenance by Thomas Bushnell, n/BSG, Francois Pinard, Paul Eggert, and Sergey Poznyakoff with many contributors.

GNU tar development also reflects the long evolution of archive formats and recovery needs. The manual notes that active development and maintenance resumed after the project was put on CVS at Savannah in July 2003, and it credits Sergey Poznyakoff with POSIX archive support.

### 採用の歴史

tar began as a tape archiver, but GNU tar helped make tar archives a routine interchange format for free software. The GNU manual explicitly notes that the GNU Project distributes software bundled into tar archives so related files can move as a single unit, a practice that made tarballs central to source distribution and package building.

### 使われ方

Practitioners use GNU tar to create and extract source tarballs, preserve directory trees, list archive contents, append or update members, stream archives through pipes, and combine archiving with compression tools. System administrators also use GNU tar for full and incremental backups, including snapshot-file workflows with --listed-incremental.

### パッケージ好きにとっての重要性

GNU tar is package-nerd bedrock: release artifacts, distro build recipes, reproducible archives, vendor source bundles, and backup scripts all depend on tar behavior. Details such as pax headers, sparse files, compression integration, path handling, and incremental metadata are small options with large consequences for reproducibility and restore safety.

### タイムライン

- 1980s: GNU tar grew from John Gilmore's public-domain tar into a GNU-maintained archiver.
- 2003: GNU tar was put on CVS at Savannah and active maintenance resumed.
- 2021: Version 1.34 notes record extraction and permission-handling fixes.
- 2023: Version 1.35 notes include compatibility and backup-related fixes.
- 2026: Git NEWS for 1.35.90 describes reproducibility work, extraction safety fixes, and performance improvements.

### Related projects

- GNU tar is tightly related to gzip, bzip2, xz, cpio, rmt, POSIX pax archives, source-release tooling, and package-manager build systems.
