I started looking into a wording change for this, but I'm not too
keen on where it would end up. It would have a particular difference
from chmod that would "stick out like a sore thumb", which is that
when '=' is used without a "who", find ignores the umask but chmod
uses it.
Is that what BSD find does? Or is it consistent with chmod here
(contrary to what the standard requires)?
Perhaps we should allow the difference but recommend against it.
Something like this:
The <i>mode</i> argument is used to represent file mode bits. It shall
be processed in an identical matter to the <i>symbolic_mode</i> operand
described in <i>chmod</i>, except that:
1. The changes to file mode bits shall be applied to a template instead
of to any files. The template shall initially have all file mode
bits cleared.
2. The <i>op</i> symbol '-' cannot be the first character of <i>mode</i>;
this avoids ambiguity with the optional leading <hyphen-minus>. Since
the initial mode is all bits off, there are not any symbolic modes
that need to use '-' as the first character.
3. The <i>find</i> utility may, but should not, disregard the contents of
the file mode creation mask of the process when the <i>op</i> symbol
'=' is used without <b>who</b> being specified.
If the <hyphen-minus> is omitted, ...
with a note in FUTURE DIRECTIONS:
A future version of this standard may require that the <b>-perm</b>
primary uses the file mode creation mask in an identical manner to
the way <i>chmod</i> uses it in the <i>symbolic_mode</i> operand.
