How to deal with the problem that file name conversion case cannot be submitted in Git

Background of the issue

In processing awesome-github-profile-readme-chinese When the PR of the project, I carefully read the content submitted by my partner and readily agreed, however, in the end, I am still young, and there is still a small problem after the merger, that is, when I preview the effect after the merger, I found that I could not load the image.

I clicked on the image link and did jump to 404, and when I looked closely, it turned out that the name of the quoted picture was inconsistent with the case of the name of the picture itself:

- [xJoyLu](https://github.com/xJoyLu)
  <details>
    <summary>Preview</summary>
    <img src="examples/xJoyLu.png">

And the actual file is called:xjoylu.png。

GitHub is sensitive to the case of filenames when loading image files, and if they are inconsistent, they will not load correctly.

So, I had to fix this little problem myself, but I found that when I changed the local image file name to match the referenced name, the commit never worked。

solution

It turns out that Git is configured to ignore case by default, so case changes cannot be detected correctly.

Here are three solutions to collate.

Option one

Modify Git's default configuration to make it case-sensitive:

$ git config core.ignorecase false

Run the above command to turn off Git ignore case configuration to detect case changes.

Option II

You can first move the image out of the project, then submit, submit, and then move back, submit again, or you can achieve the goal.

Option three

Use the git mv command to modify the file name:

$ git mv xjoylu.png xJoyLu.png

Then go through the normal submission process.
