There are AFAIK _no_ binaries that are "not intented to be executed by users or shell scripts". The object files are, indeed, not what the every day user may want to use, but they *are* used indirectly when a C program is linked: $ find /usr/lib | \ grep -v '\.a$' | grep -v '\.so$' | grep -v '\.so.[0-9][0-9]*$' | \ xargs ls -ld drwxr-xr-x 4 root wheel 8704 Jan 10 16:38 /usr/lib drwxr-xr-x 2 root wheel 512 Jul 21 18:41 /usr/lib/aout drwxr-xr-x 3 root wheel 512 Oct 12 12:56 /usr/lib/compat drwxr-xr-x 2 root wheel 2048 Oct 11 14:30 /usr/lib/compat/aout -r--r--r-- 1 root wheel 1360 Jan 10 16:35 /usr/lib/crt1.o -r--r--r-- 1 root wheel 1856 Jan 10 16:36 /usr/lib/crtbegin.o -r--r--r-- 1 root wheel 2220 Jan 10 16:36 /usr/lib/crtbeginS.o -r--r--r-- 1 root wheel 1212 Jan 10 16:36 /usr/lib/crtend.o -r--r--r-- 1 root wheel 1260 Jan 10 16:36 /usr/lib/crtendS.o -r--r--r-- 1 root wheel 876 Jan 10 16:35 /usr/lib/crti.o -r--r--r-- 1 root wheel 832 Jan 10 16:35 /usr/lib/crtn.o -r--r--r-- 1 root wheel 1524 Jan 10 16:35 /usr/lib/gcrt1.o -r--r--r-- 1 root wheel 8410 Jan 10 16:37 /usr/lib/kgzldr.o $ The description of hier(7) is a bit terse, but it is true IMHO. - Giorgos On Mon, 10 Jan 2005 17:15:06 +0200, Giorgos Keramidas <keramida@ceid.upatras.gr> wrote: > > I don't really understand the /usr/lib entry in the hier man page: > > > > lib/ archive libraries > > Libraries *are* 'archives'. Archives of object files. I just found a webpage (http://docs.hp.com/en/B2355-90655/ch05s01.html) about HP-UX explaining that there are two types of libraries: shared and archive libraries. Archive libraries are indeed archives of object files created with the ar command. I am not a programmer, and didn't know about that; therefore my confusion. > The description of hier(7) is a bit terse, but it is true IMHO. Absolutelly. Maybe it should be explained somewhere what an archive library is? The handbook does not explain about it. Thanks for your time and reply, Quique -- It's never too late to have a happy childhood.

I can change the description of /usr/lib to: lib/ shared and archive ar(1)-type libraries Does this seem a good way to point the reader to ar(1) -- where a good explanation of what archive libraries are can be found?

Yes! That sounds just nice :-) Thank you, Quique -- It's never too late to have a happy childhood. State Changed From-To: open->patched I committed a nicer description to CURRENT. Thanks :-) Responsible Changed From-To: freebsd-doc->keramida I will MFC this to RELENG_5 in a few days. State Changed From-To: patched->closed Merged to RELENG_5 in revision 1.110.2.1. |
[N.B.: I am not a native English speaker, so this might actually be my problem]. I don't really understand the /usr/lib entry in the hier man page: lib/ archive libraries Fix: The FHS explanation seems more clear: /usr/lib : Libraries for programming and packages /usr/lib includes object files, libraries, and internal binaries that are not intended to be executed directly by users or shell scripts.
