Thanks, I was getting really frustrated with this. I knew about the old environment variable but had no idea it had changed.

Thanks! Cleaning up those "._" files had gotten real annoying.

Exactly what I wanted. Thanks very much!

I should just note that while such features have largely gone out of use with Mac OS X, the resource fork's capabilities go far beyond storing file-type information. The resource fork is nothing less than a comprehensive database capable of holding all sorts of information - including icons, pictures, text, programme code, and so on - in a standard format accessible using only standard system routines. In fact, prior to the switch to PowerPC, most programmes consisted entirely of resources, with nothing in their data fork whatsoever.

That was the solution for me. I tried it with --exclude, but that didn't work for me. Thanks!

This almost reads like a submission to the Daily WTF...

Thanks for documenting these environment variables.

THANKS THANKS THANKS! I was looking for ages for this switch in Leopard.

COPYFILE_DISABLE works on Snow Leopard as well.

Made my day; thanks for this! I confirm, as well, that this works in Snow Leopard.

Cheers for this article, its one of the better write-ups on the root cause and solution.

Nice work!

Thank you - I've been struggling with this for a while!

Works on Lion too ! Thx.
