more nitpicky pedantry, but i was summarizing some handy system H/W utilities and noticed that, while lsusb and lspci philosophically do the same thing (that is, display system info), on my fedora system, they are installed differently: $ type lsusb lsusb is /usr/bin/lsusb $ type lspci lspci is /usr/sbin/lspci $ obviously, it's not a big deal since both /usr/bin and /usr/sbin are part of the normal search path for even regular users, but i was reminded of the excruciating detail of the filesystem hierarchy standard and was wondering if there was anything in the recent FHS 3.0: http://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html that had anything to say about a distinction between those two directories. there's nothing noticeably different between those two commands in terms of basic properties: $ ls -l /usr/bin/lsusb -rwxr-xr-x. 1 root root 208720 Dec 3 22:09 /usr/bin/lsusb $ ls -l /usr/sbin/lspci -rwxr-xr-x. 1 root root 83704 Aug 4 2017 /usr/sbin/lspci $ that suggests one is more of a "system" utility than the other. so is this just arbitrary, or is there anything in the FHS that addresses this sort of thing? rday
