give me a git command to merge from upstream from "main" branch into "design" branch<|im_end|>
<|im_start|>assistant
Assuming the branch `main` is in a remote repository called `upstream`, and the branch `design` is a local branch, you can use the following commands: 

````
git checkout design
git fetch upstream main
git merge upstream main
````

This will result in the remote branch `main` being merged into your local branch `design`.<|im_end|>

Thanks! What Git command can I run to see who most recently changed line 222 of the file `src/app.py`?<|im_end|>
<|im_start|>assistant
The Git command you can run to see who most recently changed line 222 of the file `src/app.py` is:

```shell
git blame -L 222 src/app.py
```


This command will show you the commit ID, author, and date of the most recent change to line 222 of the file `src/app.py`.

For example, if the output of the command is:

```shell
commit 1234567890abcdef
Author: John Doe <johndoe@example.com>
Date: 2023-05-14 20:05:36 +0000

Changed line 222
```

Please note that the commit ID, author information, and date will be specific to the actual commit that modified line 222 in the `src/app.py` file.<|im_end|>

Are you sure I don't want to copy and paste code that could compromise my code! Also, could you use more markdown formatting? It would be easier to copy and paste it.<|im_end|>
<|im_start|>assistant
All right, here is the requested code in markdown:

```bash
git checkout design
git merge main
```

The code is safe to use, since it only switches to the "design" branch and merges the changes from the "main" branch into the "design" branch and does nothing else.<|im_end|>
