Unfortunately I was hit with the bug when backing up several large photo directories with hard-links to one target directory on an external drive. So it was not obvious for me at first, that something was going wrong. From my point of view (without looking at the source) it should be easy to repair by - not attempting to create a hard-link from a file to itself - not deleting a file that is about to be used as the source paramter of a hard-link to be created. best regards Steffen Zahn On Tue, Jun 30, 2015 at 9:02 AM L.

I think you'll find this was reported 3 years ago..
"bug#10471: Severe or critical - deletes existing files and leaves
nothing. (cp)"
https://lists.gnu.org/archive/html/bug-coreutils/2015-04/msg00001.html
Unfortunately it was closed it out w/the reason that it was a
"cygwin/windows-only"
-- which I disagreed with. I was told the cygwin dev would check it out and
if it was in coreutils would move it back to active status (that was 3+
years ago).

Hello,
I found that the cp command acts "sub-optimal" when copying hard-linked
files of the same name from several directories to one target directory, it
first copies the files then removes them. I cannot see how that can be the
intended behaviour. Please fix this.
best regards
Steffen Zahn
