How to remove remote origin from a Git repository
Instead of removing and re-adding, you can do this: See this question: How to change the URI (URL) for a remote Git repository? To remove remote use this:
Hard reset of a single file
You can use the following command: … which will update both the working copy of my-file.txt and its state in the index with that from HEAD. — basically means: treat every argument after this point as a file name. More details in this answer. Thanks to VonC for pointing this out.

error: cannot lock ref.. ‘refs/tags’ exists; cannot create ‘refs/tags/
Your Git is complaining that a reference (rather than a directory) named refs/tags exists. It’s not clear what would create that, but see if git rev-parse refs/tags produces a hash ID. If so, that reference needs to go away: after which git fetch should work. If git rev-parse refs/tags fails (which it should—refs/tags itself should not be a valid name) then this is not the problem and it’s … Read more
The following untracked working tree files would be overwritten by merge, but I don’t care
The problem is that you are not tracking the files locally but identical files are tracked remotely so in order to “pull” your system would be forced to overwrite the local files which are not version controlled. Try running This will track all files, remove all of your local changes to those files, and then … Read more
Superscript in markdown (Github flavored)?
Use the <sup></sup>tag (<sub></sub> is the equivalent for subscripts). See this gist for an example.
git status (nothing to commit, working directory clean), however with changes commited
Your local branch doesn’t know about the remote branch. If you don’t tell git that your local branch (master) is supposed to compare itself to the remote counterpart (origin/master in this case); then git status won’t tell you the difference between your branch and the remote one. So you should use: or with the short option: This options –set-upstream-to (or -u in … Read more
What do raw.githubusercontent.com URLs represent?
The raw.githubusercontent.com domain is used to serve unprocessed versions of files stored in GitHub repositories. If you browse to a file on GitHub and then click the Raw link, that’s where you’ll go. The URL in your question references the install file in the master branch of the Homebrew/install repository. The rest of that command just retrieves the file and runs ruby on its contents.
Throw away local commits in Git
If your excess commits are only visible to you, you can just do git reset –hard origin/<branch_name> to move back to where the origin is. This will reset the state of the repository to the previous commit, and it will discard all local changes. Doing a git revert makes new commits to remove old commits in a way that keeps everyone’s history sane.
