概要
Extract Digicam setting info from EXIF JPEG headers
履歴
jhead is Matthias Wandel's small command-line utility for displaying and modifying metadata in digital-camera image files. It began as an EXIF inspection tool for JPEGs and later grew practical metadata operations such as timestamp adjustment, thumbnail handling, comment editing, metadata stripping, and orientation-based rotation.
The official README says Wandel first wrote jhead in 1999, when there was not much software for looking inside EXIF headers. The source file header records development from December 1999 through March 2026, and the repository preserves the author's long-running public-domain C utility.
The project's own notes explain its design goal: stay small, simple, and understandable rather than compete with larger metadata suites. Wandel explicitly points users who need broad metadata coverage to ExifTool or Exiv2, while positioning jhead as a fast utility and readable codebase for understanding EXIF internals.
jhead spread through Unix package collections because it filled an everyday digital-camera need with one C executable. The README notes availability in many Linux distributions and ports trees, and the Homebrew formula preserves it as a compact image-metadata command.
Its adoption belongs to the early digital photography era, when users wanted shell tools to rename photos by capture time, fix camera clock mistakes, rotate JPEGs according to orientation tags, and strip or inspect metadata in batches.
jhead is commonly used to print camera settings, set file timestamps from EXIF dates, adjust EXIF time fields, rename files using photo timestamps, remove metadata sections, edit comments, and invoke jpegtran for lossless rotation according to EXIF orientation.
The tool is deliberately not a general metadata framework. Its docs tell users to reach for ExifTool or Exiv2 when they need broader format or tag coverage.
jhead is a classic package-manager utility: tiny, scriptable, portable C, no service dependency, and useful in pipelines. It is the kind of tool that persists in distro archives because it solves a narrow job with little operational weight.
It also documents a useful package-design tradeoff. Rather than absorb every EXIF feature, it keeps a stable small-tool identity while coexisting with heavier metadata projects.
