Git ignore files being tracked WITHOUT DELETING THEM

git, version-control

Solution

If I understand your question correctly, you want `repo2` to know about the `ignoreme/` directory, but you don't want Git to care about any modifications to the directory. And `git rm --cached` won't help you because you're telling Git to stop tracking this content from now on.

Git's solution for keeping track of content, but fixed at a certain point, is through submodules. This except from the Git Book explains (emphasis added):

Although `rack` is a subdirectory in your working directory, Git sees it as a submodule and doesn’t track its contents when you’re not in that directory. Instead, Git records it as a particular commit from that repository.

You could try the following:

Copy the `ignoreme/` directory to a new location, and make it a git repository

Add it back as a submodule in `repo2`:

git submodule add file:///path/to/ignoreme ignoreme
git commit -m"Add ignoreme/ as a submodule"

The `ignoreme` submodule is now fixed to a particular commit. `repo2` is still tracking whatever content is inside the submodule, but any changes to files in `ignoreme/` will not be tracked in `repo2` unless you commit them in the submodule. Let's say `ignoreme/ignore.txt` was modified somehow:

$ git status
# On branch master
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#   (commit or discard the untracked or modified content in submodules)
#
#       modified:   ignoreme (modified content)
#
no changes added to commit (use "git add" and/or "git commit -a")

Even if you run `git add .`, the changes in `ignoreme/ignore.txt` will not be added to the index unless they are committed to the submodule like so:

$ cd ignoreme
$ git commit -am"Time to change ignore.txt"
$ cd ..
$ git add .
$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       modified:   ignoreme
#

However if you want to forget the local modifications in the submodule:

$ cd ignoreme
$ git reset --hard
$ cd ..

Problem

I'm having some trouble understanding basic git concepts :/ I'm testing on my local Windows machine before trying some things on my git-controlled site. I have: ``` gittesting/repo1: file.txt ignoreme: ignore.txt ``` and ``` gittesting/repo2 file.txt ignoreme: ignore.txt ``` Repo2 is a copy of repo1, and ignoreme is already being tracked. The ignore.txt file becomes changed in repo2, but I want to stop tracking it and for git to completely ignore it. The problem is that if I create a .gitignore file and add ignoreme, it's too late because it's already being tracked, so I would have to do git rm --cached ignore, but then it's marked as deleted and if I pulled the commit to repo1, the directory would be deleted instead of being left alone.. To sum it up: - The ignore.txt have different content between the two repos. - I want the ignore.txt contents to remain as they are and be completely ignored by git I've looked online, asked in the IRC, and looked at the very related questions, but can't find a way to do this. I know the example seems trivial, but it's exactly what I need to do on my site, where the directory is Forum/cache instead. edit: This is a bit of a hack and I'd prefer a better answer, but I ended up doing: ``` cd repo2 echo "ignoreme" > .gitignore echo "ignoreme/*" > .gitignore git rm --cache -r ignoreme git commit -m "Should ignore now" cd ../repo1 mv ignoreme ignoreme2 git pull ../repo2 mv ignoreme2 ignoreme ```
