Ok, while we're at being precise: The above is true as long as the "t" bit
is not set. Example: /tmp on many systems has the permissions drwxrwxrwt -
that means anybody can write to that directory, but only the owner of a file
(and root, obviously) can remove a file.
The info page of GNU chmod states that the "t" bit has this function on
"some systems", so I assume it's not the same on all *nixes. I know for sure
that it works under SunOS/Solaris.
Another two pence,
Thomas
