In principle I have no strong opinion on what the behaviour should be. But if one strictly follows the POSIX wording:
> The following exit values shall be returned: > 0 > All input files were [copied/moved] successfully. > >0 > An error occurred. The change seems to make sense, as one could argue that the above ain't the case with -n if the destination already exists. It's however open to debate whether --no-clobber - were it in POSIX - would have fallen into that spirit. But at least as of corutils 9.1 's cp info page it was documented as: >An exit status of zero indicates success, and a nonzero value >indicates failure. together with: > ‘-n’ > ‘--no-clobber’ > Do not overwrite an existing file; silently do nothing instead. > This option overrides a previous ‘-i’ option. This option is > mutually exclusive with ‘-b’ or ‘--backup’ option. that doesn't seem like failure to me. So it kinda breaks the "promise" made by the documentation. I like Pádraig's idea in message #26... but no idea whether it should be more POSIX like (thus non-zero when nothing was copied) or more backwards compatible. Cheers, Chris.
