git排除已添加追踪的文件

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:

git rm -r--cached .

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

gitadd .

Step 4: Commit

gitcommit -m".gitignore fix"

Your repository is clean :)

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