Operating Systems OS X (Apple) OSX: ./Users/myname OR. /usr/myname ? 1) what is the truth on UNIX ./usr/ directory. Post 303004700 by [MA]Flying_Meat on Friday 6th of October 2017 06:24:00 PM

I may be waaaaayyyy off base here, but I had always considered /usr as a receptacle for things that aren't part of the base OS.
As there are /bin and /sbin, there are /usr/bin and /usr/sbin. These are for third party additions of binaries or scripts.
Likewise, /usr/local/bin and usr/local/sbin for things the user creates for themselves.

Third part application bundles though, should go in /Applications for all users, or /Users/username/Applications (not a thing, by default, and the applications have to be able to handle that location, too).

What reeeeeeealy bugs me is the undefined status of what is an Application, and what is a Utility. Smilie

lint(1B)                                             SunOS/BSD Compatibility Package Commands                                             lint(1B)

NAME
lint - C program verifier SYNOPSIS
/usr/ucb/lint [options] DESCRIPTION
/usr/ucb/lint is the interface to the BSD Compatibility Package C program verifier. It is a script that looks for the link /usr/ccs/bin/ucblint to the C program verifier. /usr/ccs/bin/ucblint is available only with the SPROcc package, whose default location is /opt/SUNWspro. /usr/ucb/lint is identical to /usr/ccs/bin/ucblint, except that BSD headers are used and BSD libraries are linked before base libraries. The /opt/SUNWspro/man/man1/lint.1 man page is available only with the SPROcc package. OPTIONS
/usr/ucb/lint accepts the same options as /usr/ccs/bin/ucblint, with the following exceptions: -Idir Search dir for included files whose names do not begin with a slash (/) prior to searching the usual directories. The directories for multiple -I options are searched in the order specified. The preprocessor first searches for #include files in the directory containing sourcefile, and then in directories named with -I options (if any), then /usr/ucbinclude, and finally, in /usr/include. -Ldir Add dir to the list of directories searched for libraries by /usr/ccs/bin/ucblint. This option is passed to /usr/ccs/bin/ld. Directories specified with this option are searched before /usr/ucblib and /usr/lib. -Y P, dir Change the default directory used for finding libraries. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
/usr/lint/bin/ld link editor /usr/lib/libc C library /usr/ucbinclude BSD Compatibility directory for header files /usr/ucblib BSD Compatibility directory for libraries /usr/ucblib/libucb BSD Compatibility C library /usr/lib/libsocket library containing socket routines /usr/lib/libnsl library containing network functions /usr/lib/libelf library containing routines to process ELF object files /usr/lib/libaio library containing asynchronous I/O routines ATTRIBUTES
