Hey,
The man page for find(1) does not mention when the -exec primary
evaluates to true.
-exec utility ... ; evaluates to true when the utility exits with a
zero exit status, while -exec utility ... {} + always evaluates to true.
I have a patch below with my attempt at a description. I tried to make
the wording consistent with other parts of the man page.
Cheers,
Kris Katterjohn
