GCC hosted a manual titled Guide to GNU jar utilities, documenting fastjar and grepjar as command-line utilities. ### Adoption history fastjar's adoption has been historical and distribution-driven rather than community-growth driven. It appears in Unix package managers as a compatibility tool for older Java/GNU Classpath and GCC Java workflows, while modern Java installations generally provide jar through the JDK. ### How it is used The GCC manual describes fastjar as the tool to invoke for JAR archive operations and grepjar as the companion search utility. In practice it is installed when a small, standalone jar-compatible command is needed in old build recipes or minimal packaging environments. ### Why package nerds care Package maintainers care about fastjar mostly as fossil infrastructure: it is a reminder of the period when free Java tooling had to replace proprietary pieces one command at a time, and it remains packaged because old build graphs sometimes still name fastjar explicitly. ### Timeline - 2006: fastjar project registered on Savannah. - 2006: GCC 4.0-era online docs published the fastjar and grepjar manual. - 2026: Homebrew still packages fastjar 0.98 as an implementation of Sun's jar tool. ### Related projects - Sun/Oracle jar is the tool fastjar implements. - grepjar is shipped and documented as fastjar's companion utility. - GNU Classpath and GCC Java-era packaging are the ecosystem context in which fastjar mattered most. ### Sources -
