and here i thought IBM was unable to make product neutral articles. a nice little "getting started and understanding the UNIX file system" article. I am just not sued to seeing an IBM article that didn't shamelessy plug AIX like crazy ;)

I have to agree, this was a very nice and informative article. I did find one error, regarding /usr/local and how it's used, but *BSD uses /usr and /usr/local in a very nontraditional way at least as compared to other UNIX systems. The article is correct for non-BSD oses, however.

I'd rather say it's a different interpretation of a concept, not an error.

BSD differentiates between "the OS" (core system) and "everything else". For the last part, it's completely (!) situated inside /usr/local.

See: http://www.freebsd.org/cgi/man.cgi?query=hier&apropos=0&sektion=0&m...

Linux doesn't have such a differentiation. Here, even the OS part is usually designed by packages (or something similar). The creator of a distributions decides what belongs to the distribution. Therefore, you can see different uses among the different Linusi. Some use /opt, others don't.

On Sun Solaris systems, there are again other substructures in /usr that nobody knows outside the Sun environment. :-)

There are other interpretations, such as "use /opt for things that you've compiled yourself that isn't available from your distributions source repository / ports system" or "the home directories are in /export/home".

Among the UNIXes and between UNIX and the Linusi there are differences, but if you understood why these directory structures are there, why they are well intended and what their historical reasons are, you will have no problems finding your way, no matter which UNIX or Linux you're using. I think this article gives a good introduction to this topic.

IBM tends to write some very good articles about UNIX topics.
