It borrows grep's interface style for a networking-specific job: select or reject log lines by address range. ### Projektgeschichte Jem Berkes identifies the pc-tools.net grepcidr as the original project, created in 2004 and released as grepcidr 2.0 on 2014-05-26. The official page emphasizes that the 2.0 line is distinct from John Levine's separately developed fork, even though both names can confuse users. Version 2.0 added IPv6 support, replaced a regex-based scanner with a hints scanner reported as faster on some platforms, enforced stricter IP text matching, added multiple file arguments, supported unlimited input line length, and improved CIDR validation. ### Adoptionsgeschichte grepcidr's niche is operational networking: mail filtering, network security, log analysis, and custom pipelines where a full IP-address database or firewall tool would be too heavy. Its adoption in package managers follows from being a single-purpose Unix filter with no documented configuration or credential state. ### Wie es verwendet wird The official examples show grepcidr matching an IPv6 documentation prefix against a log file and matching a Googlebot-era IPv4 CIDR range against access.log. Options include count output, inverted matching, strict CIDR alignment, strict start-of-line matching, command-line patterns, and pattern files. ### Warum Paket-Nerds sich dafür interessieren grepcidr is package-nerd significant because it is a tiny specialist filter that fills a gap between grep and heavier network-analysis tools. It lets shell users keep grep-like pipelines while making CIDR math correct enough for log and abuse workflows. The official fork note matters for packaging: downstreams need to know whether they are shipping Berkes' grepcidr 2.0 line or Levine's unrelated implementation. ### Zeitleiste - 2004: Original grepcidr project created, according to the official project page. - 2014: grepcidr 2.0 released with IPv6 support, faster scanning, stricter matching, and multiple-file support. - 2014: Official page documented the distinction between Berkes' project and the separately developed grepcidr-2 fork. ### Related projects - grep is the interface model for matching and inverted matching. - John Levine's grepcidr-2 fork is called out by the official page as an unrelated implementation. - Spamhaus is credited on the official page for sponsorship and testing of features. ### Quellen - ## Sicherheitshinweise broad file, network, media, or database tool signal. - **Geiger-Risiko:** blue / mittel - broad file, network, media, or database tool signal ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** grepcidr - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - Debian apt - grepcidr - 2.0-2: normalized package name match | Debian stable package indexes: grepcidr from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Filter IP addresses matching IPv4/IPv6 CIDR/network specification | http://www.pc-tools.net/unix/grepcidr/ - Nix - grepcidr: normalized package name match | nixpkgs package indexes: pkgs/by-name/gr/grepcidr/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - grepcidr - 2.0-2: normalized package name match | Ubuntu 24.04 LTS package indexes: grepcidr from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Filter IP addresses matching IPv4/IPv6 CIDR/network specification | http://www.pc-tools.net/unix/grepcidr/ - dnf - grepcidr - 2.0-13.fc45: normalized package name match | Fedora Rawhide package metadata: grepcidr from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/210a2053c8e007daf9ae39c2a21daaed9b2ddd07d63ecffa597050361e73650c-primary.xml.zst | Filter IPv4 and IPv6 addresses matching CIDR patterns | https://www.pc-tools.net/unix/grepcidr/ - zypper - grepcidr - 2.0-2.8: normalized package name match | openSUSE Tumbleweed package metadata: grepcidr from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Filter IP addresses matching IPv4/IPv6 CIDR specification | http://www.pc-tools.net/unix/grepcidr/ - MacPorts - grepcidr: normalized package name match | MacPorts ports tree: sysutils/grepcidr/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Verwandte Links - [Secret-risk packages](https://pkg.so/de/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/de/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://pkg.so/de/brew-utility-packages/) - Matched Homebrew package provider. - [asn](https://pkg.so/de/brew/asn/) - Popular package that depends on this formula. - [grepip](https://pkg.so/de/brew/grepip/) - Shares pkgdb curated category or tags: cli, ip-filtering, ipv4, networking. - [subnetcalc](https://pkg.so/de/brew/subnetcalc/) - Shares pkgdb curated category or tags: cli, ipv4, networking. - [sipcalc](https://pkg.so/de/brew/sipcalc/) - Shares pkgdb curated category or tags: cli, ipv4, networking. - [cidrmerge](https://pkg.so/de/brew/cidrmerge/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [cidr](https://pkg.so/de/brew/cidr/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [prips](https://pkg.so/de/brew/prips/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [mapcidr](https://pkg.so/de/brew/mapcidr/) - Shares pkgdb curated category or tags: cidr, cli, networking. - [netaddr](https://pkg.so/de/brew/netaddr/) - Shares pkgdb curated category or tags: cidr, cli, ipv4, networking. ## Combined YAML source View the package source record on GitHub.
