Commit Mistake: How to untracked files in Git
My Reason to Git stop tracking file
There are a couple of reasons to untrack a file in your git repository.
Though my obvious reason is because of fat fingers.
Sometimes I accidentally committed a binary file with
git add ..
Thus it is pretty handy to know how to untrack files in Git. Plus it is super easy.
Tell Git to untrack file
git rm to Git untrack file.
git rm --cached <filename>
And if you need untrack more that one file, simply append the files:
git rm --cached <filename> <filename2> <filename3>
Both of the commands above git untrack file without deleting. This is because of the cached option. Removing the cached option will delete it from your disk.
git rm <filename>
After run this command, don't forget to commit the changes. Git update on other developers machine will automatically remove this file
Tell Git untrack folder
What about when a whole folder needs to be untracked? Removing a whole directory is simple too with the recursive option.
git rm -r --cached <folder>
If needed, ignore the file in the future
Optionally, once you have the file removed, you can add it to your git ignore file. Conveniently, this file is called gitignore.
A gitignore file is a file that tells Git which files or folders to ignore. Gitignore file is usually placed in the root directory of a project.

Why use 'git rm' to remove a file instead of 'rm'?
Technically they are both the same.
git rm does 2 commands at once:
1. Removing the file from index
2. Staging the next commit with the removed file
rm only removes the file from disk. You will still the to stage and commit the deleted file.
git rm does that in one single step.
