git 忽略更改但不删除文件

Question

Essentially I made a mistake to not include 2 directories in .gitignore before I had to make some analysis. The result is that these analysis have produced an overwhelming amount of files and now I have 5000 tracked changes on my git repository. I would like to ignore those changes and make git look at my updated .gitignore , but I don't want to remove any of the files produced by my analysis. What is the appropriate git command for that please.

Is it git reset --hard [HEAD] ? I don't want to make any silly mistakes.

Answer 1

just remove all git cache:

git rm -r --cached .

When all files are removed from the index, you can add the regular files back (the one you did not want to ignore)

$ git add .
$ git commit -am 'Removed files from the index (now ignored)'
$ git push
