git remote add origin $ git push -u origin master

Actually, the first line of the instructions will say $ git remote add origin

git submodule deinit <asubmodule> git rm <asubmodule>

  1. Note: asubmodule (no trailing slash)
  2. or, if you want to leave it in your working tree

git rm --cached <asubmodule> rm -rf .git/modules/<asubmodule>

git config --global http.postBuffer 157286400

Deleting the .git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:

git checkout --orphan latest_branch
Add all the files
git add -A
Commit the changes
git commit -am "commit message"
Delete the branch
git branch -D master
Rename the current branch to master
git branch -m master
Finally, force update your repository
git push -f origin master

For Locally Existing Repositories

If we have the repository already cloned:

List the Git remote of the repository, git remote -v

Check whether the URL matches our GitHub host to be used, or else update the remote origin URL.

git remote set-url origin

Ensure the string between @ and : matches the Host we have given in the SSH config.

and for submodules

In simple terms, you just need to edit the .gitmodules file, then resync and update

vim .gitmodules

then resync and update:

git submodule sync git submodule update --init --recursive --remote

It’s very easy to end up here on accident, and be confused about the error message Git is complaining about despite having done nothing wrong. Luckily, it’s incredibly easy to fix:

If you just checked out a commit, and haven’t touched the repository otherwise (no new commits were made), you can simply move the HEAD back to where it belongs with git checkout:

git checkout master

This is basically like running cd on Linux, except Git still associates cached commits and changes with the old HEAD, so you don’t want to checkout if you have commits or changes that would be left hanging.

If you did have some changes, and want to just throw them away, you can hard reset back to master:

git reset --hard origin/master git clean -d --force
