Operating Systems OS X (Apple) OSX: ./Users/myname OR. /usr/myname ? 1) what is the truth on UNIX ./usr/ directory. Post 303003440 by drl on Wednesday 13th of September 2017 05:25:05 PM

Hi.

There is no single place, noting that Jim makes a good point about system disks.

There are some generalizations, however:

1) I have had stuff that I have purchased ( e.g Canvas, TheBrain, etc.) go into /Applications,

2) I have had some stuff from the App Store go into /Applications/Utilities,

3) Things that may be user-contributed that come from brew, fink, and port seem to be distributed like this ( from a local search utility, in which we placed notes about destinations ):
Code:
 Results for program brew (key "b")
 ( brew writes to /usr/local )

 Results for program fink (key "f")
 ( fink writes to /sw )

 Results for program port (key "p")
 ( port writes to /opt/local )

On a system like:
Code:
OS, ker|rel, machine: Apple/BSD, Darwin 16.7.0, x86_64
Distribution        : macOS 10.12.6 (16G29), Sierra

Best wishes ... cheers, drl

Edit 1: correct minor typo.

lint

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.
