Git ignore không được, cần loại những file đã có trên repo

Let’s say you have already added/committed some files to your git repository and you then add them to your .gitignore; these files will still be present in your repository index. This article we will see how to get rid of them.

Step 1: Commit all your changes

Before proceeding, make sure all your changes are committed, including your .gitignore file.

Step 2: Remove everything from the repository

To clear your repo, use:

• rm is the remove command
• -r will allow recursive removal
• –cached will only remove files from the index. Your files will still be there.
• The . indicates that all files will be untracked. You can untrack a specific file with git rm --cached foo.txt (thanks @amadeann).

The rm command can be unforgiving. If you wish to try what it does beforehand, add the -n or --dry-run flag to test things out.

Step 3: Re add everything

Step 4: Commit

Your repository is clean 🙂

Push the changes to your remote to see the changes effective there as well.
