# Description
Hi,
This closes #10446 , wherein we start implementing `mv` from `uutils`.
There are some stuff to iron out, particularly
* Decide on behavior from ignored tests 
* Wait for release/PRs to be approved on `uutils` side, but still can be
tested for now. See [PR
approved](https://github.com/uutils/coreutils/pull/5428), and
[pending](https://github.com/uutils/coreutils/pull/5429).
* `--progress` does not seem to work on `uutils mv` either and have not
checked whether certain `X` size has to be achieved in order for it to
appear, thus something to investigate as well, but thought it wasnt
important enough to not make the PR.

See [issue
comment](https://github.com/nushell/nushell/issues/10446#issuecomment-1764497988),
on the possible strategy to follow, mainly copy what we did with `ucp`.

I still left some comments on purpose particularly on tests, which of
course would be removed before something is decided here. :) @fdncred
