The GitHub repository identifies the project as flexible field/token extraction and has been public on GitHub since 2011. ### 采用历史 Homebrew packages fex as a stable formula at version 2.0.0. Its official project page directs release downloads to GitHub, making the GitHub repository the practical source and release surface for package maintainers. ### 使用方式 Typical use is pipeline text processing: provide delimiters and field selectors to pull fields from log lines, paths, or colon-separated records. The official docs position it as a concise alternative to repeated cut or awk invocations for selected field extraction. ### 为什么软件包爱好者会关心 fex matters to CLI package users because it sits in the classic Unix text-filter niche: tiny executable, no service state, and a focused syntax that makes package-manager installation convenient for shell pipelines. ### 时间线 - 2010: Official fex project page published. - 2011: GitHub repository created. - 2021: GitHub repository last pushed according to GitHub metadata. - 2026: Homebrew formula reports stable version 2.0.0. ### Related projects - The README says fex is related to cut, awk, and ksb's xapply field extraction syntax. ### 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 ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** fex - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 其他软件包管理器记录 - Debian apt - fex - 20160919-2: normalized package name match | Debian stable package indexes: fex from https://deb.debian.org/debian/dists/stable/non-free/binary-amd64/Packages.xz | web service for transferring very large files | http://fex.rus.uni-stuttgart.de/ - Debian apt - fex-utils - 20160919-2: normalized package name match | Debian stable package indexes: fex-utils from https://deb.debian.org/debian/dists/stable/non-free/binary-amd64/Packages.xz | web service for transferring very large files (utils) | http://fex.rus.uni-stuttgart.de/ - Nix - fex: normalized package name match | nixpkgs package indexes: pkgs/by-name/fe/fex/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - fex - 20160919-2: normalized package name match | Ubuntu 24.04 LTS package indexes: fex from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | web service for transferring very large files | http://fex.rus.uni-stuttgart.de/ - Ubuntu apt - fex-utils - 20160919-2: normalized package name match | Ubuntu 24.04 LTS package indexes: fex-utils from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | web service for transferring very large files (utils) | http://fex.rus.uni-stuttgart.de/ - dnf - fex - 2.0.0-25.fc44: normalized package name match | Fedora Rawhide package metadata: fex from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Field split/extraction like cut/awk | http://semicomplete.com/projects/fex/ ## 相关链接 - [Terminal utility packages](https://www.automicvault.com/zh-hans/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/zh-hans/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/zh-hans/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/zh-hans/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [align](https://www.automicvault.com/zh-hans/pkg/brew/align/) - Shares av.db curated category or tags: cli, developer-tools, text-processing, unix-filter. - [pk](https://www.automicvault.com/zh-hans/pkg/brew/pk/) - Shares av.db curated category or tags: cli, developer-tools, field-extraction, text-processing. - [bsdconv](https://www.automicvault.com/zh-hans/pkg/brew/bsdconv/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [cconv](https://www.automicvault.com/zh-hans/pkg/brew/cconv/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [cmigemo](https://www.automicvault.com/zh-hans/pkg/brew/cmigemo/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [decasify](https://www.automicvault.com/zh-hans/pkg/brew/decasify/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [desed](https://www.automicvault.com/zh-hans/pkg/brew/desed/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [enca](https://www.automicvault.com/zh-hans/pkg/brew/enca/) - Shares av.db curated category or tags: cli, developer-tools, text-processing. - [nkf](https://www.automicvault.com/zh-hans/pkg/brew/nkf/) - Local package facts share a topical domain.
