jilagre, it may be a shorter list if you nominate those unix and Linux Operating Systems of which you have personal experience and you can prove that it works. I don't recall a post nominating one.
Solaris 10 and HP-UX 11 onwards are already definites.
There was a reason that I deduced that "{}" was needed - it has happened to me before.
My interpretation of "man find" is that the filename list resulting from the "find" is made available to the exec command as {} . It can appear on the exec line multiple times which can be handy for renaming files. The debate starts when the filename contains space characters. I maintain that many versions of unix or Linux through the ages require "{}" , and I use that syntax out of habit.
I haven't forgotten that the "find ... -exec" was a quick way to crash System V release III with "too many forks". That was when I started using alternative techniques, but I do still find some use for "find ... -exec".
There was somebody posting earlier who had Tru64 (aka DEC unix). I can't be sure whether it worked on that one beacause all my library scripts contain "{}".
Other posters may wish to try the commands on their Operating System and contribute to this debate. Please be careful with "rm" and use "echo" where possible just in case {} does not do what you expect (like what happened to the original poster in this thread).
