[plug] mv (move) problem/bug

[Timothy White]

I appear to have found a bug in mv. Ether that I am not understanding
the behaviour.
This works with multiple versions with the latest I've tried being 5.0.91.
Basically I have a script that needs to call mv to move a file IF the
file doesn't exist in the destination.
I use 'mv --reply=no' and 'mv -i --reply=no' and it still overwrites the
existing file.

Am I doing something wrong? I've tried setting noclobber under bash but
it still happens.

I'm thinking that this is a bug or a case of the behaviour being
different from expected. I've not yet googled or tried updating
coreutils (Debian Testing) so I'll try that but it does appear to be a
bug. I'm going to look for the src code as well.
