## Historique du projet et usages
Homebrew's netcat formula packages GNU Netcat 0.7.1, a GPL implementation of the classic nc-style tool for reading and writing TCP/UDP connections. Its own homepage frames it as both a scriptable back-end and a network debugging/exploration utility, with outbound and inbound connections, tunneling, and port-scanning features.
### Historique du projet
GNU Netcat is separate from the original Hobbit netcat lineage. The GNU project page records active development milestones in 2002, including a beta label starting with version 0.4 on May 15, 2002, and a core rewrite beginning around version 0.3 on May 2, 2002. The downloads page lists 0.7.1 as the current version and gives its release date as January 11, 2004; that long-stable release is what Homebrew distributes.
### Historique d'adoption
The package's adoption is mostly legacy and compatibility-driven rather than fast-moving. On July 1, 2026, the Homebrew formula page showed 12,774 installs over 365 days and 790 installs over 30 days, evidence that people still install this GNU variant even though many systems also ship OpenBSD nc, Nmap ncat, or other netcat-compatible tools.
### Modes d'utilisation
Package nerds use it for quick socket plumbing: listen on a port, connect to a host and port, test TCP/UDP reachability, move bytes between shell pipelines and sockets, or build small ad hoc tunnels. The important packaging detail is that behavior and flags vary across netcat implementations, so installing brew:netcat is often a way to get the old GNU semantics intentionally instead of relying on the platform-provided nc.
### Pourquoi les passionnés de paquets s'y intéressent
This is a small but historically important compatibility package: not glamorous, not actively evolving, but useful when scripts expect GNU Netcat's option set. Its significance is mostly in being one of the archetypal Unix network Swiss-army-knife tools and a source of recurring packaging confusion because nc/netcat names are shared by several implementations.
