"find" ends with exit code "0" although exec command returned an error

[Thomas D.]

Hi,

for me it looks like "find" returns an invalid exit code when "-exec"
returns an error:

$ mkdir /tmp/find-test
$ touch /tmp/find-test/scripts{1..10}.sh
$ touch /tmp/find-test/text{1..10}.txt
$ find /tmp/find-test -name '*.sh' -exec chmod 755 \; \
  && echo "find succeed" || echo "find failed"

Yes, I am missing the "{}" but that's how I encounter the bug.
Output:

> chmod: missing operand after ‘755’
> Try 'chmod --help' for more information.
> chmod: missing operand after ‘755’
> Try 'chmod --help' for more information.
> chmod: missing operand after ‘755’
> Try 'chmod --help' for more information.

> find succeed

I expected "find failed" ("find" should have ended with non-zero exit code).

And yes, "chmod 755" returns an error:

$ chmod 755
chmod: missing operand after ‘755’
Try 'chmod --help' for more information.
$ echo $?
1
