Hi,
Given two files: an old version of "foo" on a mounted USB stick: /mnt/dst/foo and a new version of "foo" in /src/foo on the system's hard drive. When I do: sudo mv /src/foo /mnt/dst/foo I get the following error: mv: failed to preserve ownership for '/mnt/dst/foo': Operation not permitted The error is fine but mv deletes /src/foo and keeps mnt/dst/foo, meaning that the data of the new file is lost. Is this the intended behaviour? I'm using Coreutils 9.0. Kind regards, Frank
