I have just started to use git today.

I have a repository in project_master/project folder. I made that with git init --bare.

Then, I cd to project_work, and git clone ../project_master/project

I did some changes to the repository in project_work/project. Type make test. Didn't type make clean. After that, I git add everything, git commit, and git push origin master.

Now all the .o, .a files of the unit tests get into the repository in project_master/project folder. How to delete those .o, .a files from the repository in project_master/project folder?

Thank you.

Update:

I did the following:

~/project_work/project
cd unit_test
git rm *.o
git commit
git push origin master

Then,

cd ~/project_test
rm -rf project
rm -rf .git
ls -a
git clone ../project_master/project
cd project/unit_test

And the .o files are still there.

I also did as in this SO question: Completely remove files from Git repo and remote on GitHub. But didn't work. After that, I try git rm again and that didn't work.

You can use git rm *.o to stage their removal from git. Then use git commit to create the commit to remove them, or git commit --amend to amend the last commit that added these files and remove them from it.

  • I did that before asking this question. After that I clone the repository in `project_master/project` to a folder call `project_test`. I found that those .a files are still there. After I type those commands. I typed git push origin master. and also git push. both commands says Everything up-to-date. – rxu Jun 30 '16 at 19:54

    You need to `git push` before that commit will be in your `project_master` repository. – mkasberg Jun 30 '16 at 19:56

    Also, these types of files should go in a [`gitignore`](https://git-scm.com/docs/gitignore), which is normally committed to the root folder of your repository. – mkasberg Jun 30 '16 at 19:57
  • will definitely try gitignore. – rxu Jun 30 '16 at 20:13
  • Thanks for the answer and the helpful comments. – rxu Jun 30 '16 at 20:30

There are two common approaches:

1. Remove locally then update git

rm filename(s)
git add -u .
git commit
git push

2. Use git itself to remove the file

git rm filename(s)
git commit
git push

End result is the same, second approach is easier to use.

  • strange. the 2nd method now works too, and it didn't say Everything up-to-date this time. – rxu Jun 30 '16 at 20:27
