Let's explore the `rad patch update` plumbing command. First we create a patch:
``` (stderr)
$ git checkout -q -b feature/1
$ git commit -q -m "Not a real change" --allow-empty
```
``` (stderr)
$ git push rad HEAD:refs/patches
✓ Patch b6a23eb08656de0ef1fcc0b5fe8820841e5cb2e5 opened
To rad://z42hL2jL4XNk6K8oHQaSWfMgCL7ji/z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi
* [new reference] HEAD -> refs/patches
```
```
$ rad patch show b6a23eb08656de0ef1fcc0b5fe8820841e5cb2e5

```
We can make some changes to the repository:
```
$ git mv README README.md
$ git commit -q -m "Rename readme file"
```
Let's push the changes, but not to the magic ref, that way the push doesn't
update our patch:
```
$ git push rad HEAD:refs/heads/feature/1
```
Now, instead of using `git push` to update the patch, as we normally would,
we run:
```
$ rad patch update b6a23eb08656de0ef1fcc0b5fe8820841e5cb2e5 -m "Updated patch" --no-announce
ea7def3857f62f404606d7cd6490cd0de4eaebd1
```
The command outputs the new Revision ID, which we can now see here:
```
$ rad patch show b6a23eb08656de0ef1fcc0b5fe8820841e5cb2e5
