how to delete show diff on github - github

I recently pushed a commit to GitHub that I shouldn't have, which could have contained sensitive information. Thankfully it didn't. I immediately deleted the file in question and quickly noticed that I and anyone with access to this repo can see the contents of the uploaded file if they click on the commit history and load diff. Is there any way to delete the contents of that commit so that it no longer shows up in my repository commit history?

GitHub documents the process quite clearly.
Basic steps:
Rebase your changes and remove the offending commit from your local history.
Force push the rebased changes to GitHub.
Contact support to have the offending commit purged from pull requests, caches and issues it might be linked to.

How to delete all the commits I have made to a repository and to permanently delete a Git repository

I was brought on board as a contractor to do some work on a forked open source repository. After finishing the work and a successful launch, the hirer is ghosting me and refuses to compensate me as agreed. How can I either: permanently delete the repository without the option to restore (I still have access to Git as the owner and I'm the only one who pushed commits) or permanently delete all my pushed commits from history.
Side question: If a site is deployed on Cloudflare off a specific branch and I delete the repository, what happens? I'm assuming the webpage stays deployed based off whatever was compiled last.
In the setting of the repo scroll down to bottom you will get the danger zone. There you can archive or delete the repo. for detailed guide visit https://docs.github.com/en/repositories/creating-and-managing-repositories/deleting-a-repository
There are many ways to restore data depending on the infrastructure and the language that is used. Without more specific informations it is impossible to say how to fully delete the data. Anyways to override the history of a git branch you could use:
git push -f {branchName}

To restore deleted repo you can try sending a mail to support#github.com

Github Site shows deleted commit in the commit tab

I am new to github commands and I am a bit confused about what I am doing.
I want to delete the "MegaMan Game" commit, revert all changes, and make it dissapear from github
history. Following this other stack overflow question Delete commits from a branch in Git, I ran the git reset --hard HEAD ~1 command. The commit seems to be deleted judging by the git log command, but on the github website it still shows that the "MegaMan Game" commit is still there. Also in source tree happens the same thing. The commit still shows there.
I am a bit confused. Is the website wrong about the commits? Did I run the command wrong?
Here is an image with the exact commands and what git
This is a noob question. I need help to undestand how this works.
You deleted commit in your local branch. You must send this change to the upstream branch(to github).
git push --force

How to recover replaced files in local Git repository after pull request?

Originally on my Github are some outdated styles.css and JavaScript files and others.
I was working on my project last night but didn't push it to Github or back it up. It was just saved in my local repository using a series of local, unpushed commits.
Being a newbie that I am, I did a git pull request master, and all the files in my local repository got replaced with the original styles.css and JavaScript that was in my github.
Is there a way to get those files back?
I did a git reset head#{2} where I believe the state of the repository before the pull request was, and it showed some unstaged files.
In Gitshell my command line has "master [+10 ~19 -42 !]" with the text master being yellow.
At this point, what do I do? Currently I seem to have lost a lot of work.
If you have performed commits often you can pretty much get to any of them.
Use git reflog first (https://git-scm.com/docs/git-reflog). It will show you all the interim commits you've made. Once you find a relevant one you can do git reset #commit_id.

How can I retrieve the local changed files which I wrongly reset in git

Below is the situation which explains what's the matter about git.
I was using the 'develop' branch and already made several changes to the local files such as .sql, .java, .js...
I made a local branch called 'develop_some_future' since my boss wants to confirm my changes before merging main 'develop' repository.
Apparently my local file changes #'develop' branch have applied to 'develop_some_future' branch and I started editing local files again.
For some reason, I tried to pull the files that my co-workers already committed, but it has failed(Probably I couldn't set 'develop_some_future' branch well). So, I changed current branch to 'develop' branch and tried to pull them.
Fortunately it got worked, and then I tried to back to the 'develop_some_future' branch.
A dialog pops up suddenly while changing the branch and asked me that 'your local change for "~~~.sql" would be deleted since it's not committed yet. To avoid this, please commit that file or choose reset.'
Because I thought only '~~~.sql' would be changed to the latest committed state and that was not a problem, I selected 'reset' button, but unfortunately all local changes have gone.
Anyone knows how can I retrieve the date before reset?
I found that both 'git reflog' and 'git reset HEAD{}' commands are useful.
However, git reflog shows only commit, merge, and checkout changes and so I can't find reset status at all.
I'm afraid your files are gone for good, unless you had previously staged the file somehow (add or stash save).
If it had been staged, a blob object was created by Git which is now dangling (git fsck will tell you dangling objects). You can then resurrect the file by writing the blob's content with git cat-file to a new file.
If not, your'e screwed, and you have to do your work again.
It seems the problem arose in the first place, because you thought that unstaged/uncommitted changes belong to the current branch. They do not, and only live in the working directory. They will be carried over when switching branches (unless, of course, the same file was modified in the branch. Git will then refuse to checkout the other branch).

Github pull request loaded with empty file changes

Ok, I've got a problem that I have no idea how to go about solving.
First, a bit of history:
I pulled from my upstream to bring in changes and merged them with the branch I was working in. At the time, I may have been using a console window with root access. I say this because I noticed a day later I couldn't save to a lot of the files in my local repo. I noticed the owner / group had been changed to root and permissions were 644. After going through and hunting down all of the screwed up files, I then pushed some changes I had made back to my remote working branch.
A week later (now), and I've added several other commits to an open pull request from my remote branch. In the middle of them was the commit I made after fixing my local repo file permissions. I noticed it has some 1200 "empty" files (no changes). I'm a little concerned that merging this pull request upstream could cause big problems and I have no idea how to remove this one commit or if it's even possible...
I tried creating a new branch and using cherry-pick to get all but the one commit, but I've removed files and couldn't merge the older commits that saw a "conflict" between the file that existed at the time and one that no longer exists in the local repo...
Anyway, any thoughts?
The solution I used was to reset my local branch to the commit just before the one that I didn't want. I then copied and pasted the commits after the failed commit into code, recommited, and pushed toa new branch. Long way around, yes. But it wasn't bad as I didn't have a lot of code to fix. A simpler method might have been to use cherry-pick to pull the later commits into my reset local branch, but I tried that at one point and had problems...
