将文件重新上传到GitHub，没有任何更改？ 这有道理吗？

Question

Is there a way to re-upload a file to GitHub without changing it? The file is a .zip, and I'm wondering if it was a corrupted file; then again, if there isn't a diff, then maybe it's exactly the same.

1) Is there a way to re-upload a file, even if you haven't changed it (Ie, no changes to push).

2) In the scenario I described, does it even make sense to try?

I guess you could make a clone of the repository:

git clone git@github.com:you/yourrepo.git copy-of-myrepo

And then roll it back to a commit that doesn't have that file:

cd copy-of-myrepo
git reset --hard 12345

And then force push it:

git push -f origin master

And then go back to your original working copy and push it:

cd /path/to/myrepo
git push origin master

In the scenario I described, does it even make sense to try?

Probably not, no.

You could always verify the integrity of the zip file by downloading it and comparing a checksum on the downloaded copy against a checksum of the original archive. Eg,

sha1sum myfile.zip
