“bin”组的目的是什么?

通常在哪里使用?我可以在哪里阅读有关它和其他常用组的信息?

base-passwd软件包确保系统中存在特定的用户和特定的组。文档位于/usr/share/doc/base-passwd/users-and-groups.txt.gz(或/usr/share/doc/base-passwd/users-and-groups.html)(源代码可在Debian Salsa上在线获取):
bin

    HELP: No files on my system are owned by user or group bin. What good are
    they? Historically they were probably the owners of binaries in /bin? It is
    not mentioned in the FHS, Debian Policy, or the changelogs of base-passwd
    or base-files.

    LSB 1.3 lists bin as legacy, and says: "The 'bin' UID/GID is included for
    compatibility with legacy applications. New applications should no longer
    use the 'bin' UID/GID."

所以,这是LSB规范的一部分,由于Debian曾经追求LSB兼容性,Ubuntu有一个bin用户和组。

在历史上的Unix系统中,/usr是用户主目录的原始路径,因此有一个bin用户负责/usr/bin。与这些系统(以及一些更现代的系统,如Solaris等)实现的root用户相比,它的家目录不是/root,而是/
