This is a good observation.
Also the current "skip" functionality of coreutils cp -n
is already catered for with the --update option.
For consistency, there too the exit status should reflect whether the cp
action was done.
I installed the attached patch to implement this; comments welcome. In
the meantime I'm boldly closing the bug report.
I'm not sure I agree with making this change for --update.
Note POSIX doesn't specify -u (or -n TBH), so it's a
bit of a stretch to take its specification of
"All files were copied successfully" in this case,
when it wasn't considering these cases.
To me --update is less useful if it fails in this case.
thanks,
