Unable to track files within Git submodules

Question

Problem: to add files at ./shells/smallApps/* to Git at ./.git/ when I do not have the files at ./.git/info/exclude nor at any .gitignore -files.

This question is based on this tread where the problem is not solved completely.

I run

$git status                                                                                                                                          ~/bin # On branch master nothing to commit (working directory clean) $git ls-files                                                                                                                                        ~/bin Screen/dev/vim-open.screen --- cut --- 

I note that I do not have the files "shells/smallApps/*" at my Git

$ls shells/smallApps/                                                                                                                                ~/bin devTodo     extract                                                                                                                                                   ~/bin 

I want to add them to my Git by running

$git add shells/smallApps/devTodo shells/smallApps/extract fatal: Path 'shells/smallApps/devTodo' is in submodule 'shells/smallApps' $git add .          

I note that the files are not added to my Git for some reason such that

$git status                                                                                                                                          ~/bin  # On branch master nothing to commit (working directory clean) 

I do not have the files at .git/info/exclude nor at .gitignore -files.

What does the last warning mean?

UPDATE

There are two general reasons why Git will ignore a file: gitignore and submodules.

To be more specific, the following conditions will cause Git to ignore a file when 'git add' is invoked:

1. The file matches a pattern $GIT_DIR/exclude.
2. The file matches a pattern in a .gitignore file inside the repo.
3. The file matches a pattern in a user-specific .gitignore file (specified by 'git config --global core.excludesfile').
4. The file is part of a submodule.

Forcing 'git add' on an ignored file:

You can check to see if a particular file is ignored by invoking 'git add full/path/to/file'.

The man page states that "If an ignored file is explicitly specified on the command line, the command will fail with a list of ignored files."

If the file is ignored, you can force it to be added with 'git add --force full/path/to/file'.

Instructions to eliminate a submodule reference:

As noted in a previous answer, shells/smallApps is a submodule in your repository.

If the file is part of a submodule, the situation is more complex. You cannot modify the contents of the submodule from within the main project.

If you want to eliminate the submodule reference and directly track the files in your main repo, there are several steps that must be performed. You cannot simply remove the ".git" directory from the submodule. There are three links between your main repository and the submodule:

1. The .gitmodules file in your main repo.
2. An entry in the .git/config of your main repo.
3. Any commits related to the submodule in your main repo history.

Per this related SO question, you need to perform the following steps to completely remove the sub-module:

NOTE: If another branch depends on this submodule, then removing it can corrupt your repository! This is a dangerous operation...use with caution.

1. Delete the relevant line from the .gitmodules file.
2. Delete the relevant section from .git/config.
3. Run git rm --cached path_to_submodule (no trailing slash).
4. Commit

The files that were part of the submodule are now untracked and you may decide to keep or delete them as desired (with the one caveat mentioned below).

If you don't need these files, you may simply delete them.

Caveat: If you want to keep these files (which you appear to want), you must manually remove the .git directory from the submodule folder:

1. cd path_to_submodule
2. rm .git
3. cd ..
4. git add path_to_submodule
5. git status
6. git commit

UPDATE:

Request for further information:

To assist debugging this issue, please post the output of the following complete session of commands:

cd to the top-level directory in your repo ls -al cat .git/config find . -name ".git*" git status git add editors git add shells git status 

Based on the description of what you have done so far, I expect to see:

• No .gitmodules file anywhere
• Only one .git directory (found at the root of your repo)
• No .git directory in editors/vim/vimdoclet
• No .git directory in shells/smallApps
