Let's assume the following current folder:

in which we issue the following command
$ find . -depth -name a.txt -o -name b.txt
We get the following result:
./a.txt
./b.txt
-------- Problem 1 --------
By evaluating the expression according to the information in the manual of find
the command should return also c.txt as part of the result. Let me explain my
reasoning. The above command is equivalent to the following command:
$ find . -depth -a -name a.txt -o -name b.txt
and the expression is evaluated for each file, that is even for c.txt and
because
the result is known immediately after the evaluation of -depth (which always
returns
true) the command should print it to the standard output.
Not having c.txt in the result it seems to me that find performs the following
evaluation:
$ find . -depth -a \( -name a.txt -o -name b.txt \)
Is this correct? If so, then some information in the manual page should clarify
that all global options are (probably) evaluated only once and before the rest
of
the expression.
No, that's not correct. The behaviour is like
$ find . \( -depth -a -name a.txt \) -o -name b.txt
-depth is always true, but "true and something else" is the same as
"something else" so it still has to check -name a.txt.
Very correct. It is more than obvious that my question/interpretation was
wrong. Probably
because my reasoning was blurred by some of my expectations...
Sorry for disturbing with non-problems.
Thanks again
