Before changing laptops I backed up all my personal projects to my NAS.  When I
transfer them back the file modes got messed up and a **git status** returned
this:

```shell
diff --git a/docker/Dockerfile b/docker/Dockerfile
old mode 100644
new mode 100755
diff --git a/lib/DeployTool/CLI.rakumod b/lib/DeployTool/CLI.rakumogpg --list-secret-keys --keyid-format LONG <EMAIL>d
old mode 100644
new mode 100755
diff --git a/lib/DeployTool/Config.rakumod b/lib/DeployTool/Config.rakumod
old mode 100644
new mode 100755
```

Git diff shell magic, thanks to [Stanislav Khromov](https://snippets.khromov.se),
to the rescue!


```shell
$ git diff -p -R --no-ext-diff --no-color \
    | grep -E "^(diff|(old|new) mode)" --color=never  \
    | git apply
```

This command uses git diff and some clever grep logic to swap the file modes back to what git remembers them as.

I also converted the snippet to a shell script [here](https://paste.sr.ht/~travisshears/ee89c97e7c6a54401b28d8b71ae1f796468dcb48)
