Its project page describes it as a tool for informative JPEG listings, error checks, and optional deletion of broken JPEG files. ### 项目历史 The README records copyright years starting in 1995 and lists v1.0 as the first public release. The program was built on IJG libjpeg and kept the style of traditional command-line inspection tools: one binary, option flags, report columns, and exit codes suitable for shell scripts. Later releases added checksum support, GNU autoconf configuration, comment and Exif recognition, CSV and JSON output, stdin support, and stronger digest options. GitHub releases in January and October 2023 document the modern 1.6 and 1.7 series. ### 采用历史 jpeginfo appears in Unix package collections as a companion to image-processing pipelines, especially where maintainers need a lightweight integrity checker rather than a full image editor. Its availability through Homebrew, Debian, Fedora, MacPorts, Nix, Ubuntu, and openSUSE reflects that quiet utility role. ### 使用方式 Typical use is batch inspection of JPEG dimensions, markers, progressive/non-progressive status, comments, and optional checksum columns. The `--check` mode makes it useful in scripts that reject damaged uploads or clean photo archives. ### 为什么软件包爱好者会关心 jpeginfo is package-nerd useful because it exposes low-level JPEG facts without dragging in a heavyweight graphics stack. It pairs naturally with `jpegoptim`: one tool checks and reports, the other rewrites and compresses. ### 时间线 - 1995: Copyright period begins in the upstream README. - v1.0: First public release, as listed in the upstream history. - 2023-01-08: v1.6.2 added SHA-256 digest support and improved Win32 support. - 2023-01-16: v1.7.0 added CSV output, JSON output, stdin support, headers, and SHA-512 support. - 2023-10-29: v1.7.1 added `--files-from` and `--files-stdin`. ### Related projects - Related projects include IJG libjpeg, libjpeg-turbo, mozjpeg, and jpegoptim. ### 来源 - - - - - ## 安全说明 narrow executable package without higher-risk signals. - **Geiger 风险:** 绿色 / 低 - narrow executable package without higher-risk signals ## 其他软件包管理器记录 - Debian apt - jpeginfo - 1.7.1+dfsg-1: normalized package name match | Debian stable package indexes: jpeginfo from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Prints information and tests integrity of JPEG/JFIF files | https://www.kokkonen.net/tjko/projects.html - Nix - jpeginfo: normalized package name match | nixpkgs package indexes: pkgs/by-name/jp/jpeginfo/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - jpeginfo - 1.7.1+dfsg-1build1: normalized package name match | Ubuntu 24.04 LTS package indexes: jpeginfo from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Prints information and tests integrity of JPEG/JFIF files | https://www.kokkonen.net/tjko/projects.html - apk - jpeginfo - 1.7.1-r0: normalized package name match | Alpine Linux edge package indexes: jpeginfo from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | Prints information and tests integrity of JPEG/JFIF files | https://www.kokkonen.net/tjko/projects.html - apk - jpeginfo-doc - 1.7.1-r0: normalized package name match | Alpine Linux edge package indexes: jpeginfo-doc from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | Prints information and tests integrity of JPEG/JFIF files (documentation) | https://www.kokkonen.net/tjko/projects.html - dnf - jpeginfo - 1.7.1-9.fc45: normalized package name match | Fedora Rawhide package metadata: jpeginfo from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Error-check and generate informative listings from JPEG files | http://www.kokkonen.net/tjko/projects.html - zypper - jpeginfo - 1.7.1-1.4: normalized package name match | openSUSE Tumbleweed package metadata: jpeginfo from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Generate informative listings from JPEG files and check them for errors | https://github.com/tjko/jpeginfo - MacPorts - jpeginfo: normalized package name match | MacPorts ports tree: multimedia/jpeginfo/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
