Following the advice of a friend of mine, I started learning git. I read manual (basic sections) and I think understood most regarding commits, branches, setting backward, forward, etc. but when it comes to sync local repository with remote one, I feel slightly lost.

I am currently testing git on my `testrepository. I was adding files and folders locally, then updating a repository using website by adding additional files. Then I fetched files, merged commits and eventually I synchronised remote and local repositories. Now, I have got this log:

Firs of all, origin/master and origin/HEAD are both in red. Second, I don't understand what is origin/HEAD doing there? I though HEAD is a pointer that points at my current commit. Could someone explain if the log is ok or I messed up too much. And also how to understand `origin/HEAD.

Many thanks


HEAD has a few additional uses.

Due to HEAD being a pointer to the "current" commit, it is also the commit you get by default when cloning that repository. So in remote repositories, even though they don't have a worktree, HEAD can still exist as a pointer to the "default" branch – the one that clones will check out automatically.

(For example, some projects point HEAD of the "master" repo to a 'dev' or 'stable' branch instead of master, so that people get something more useful by default.)

In your case however, after cloning, Git keeps the <remote>/HEAD ref around because it has yet another use: it defines the branch Git tools will try if only the remote name is specified.

For example, normally you couldn't do git log origin, since refs/remotes/origin/ is a directory, thus cannot point anywhere. However, Git then automatically looks for origin/HEAD and gives you whatever branch that points to.

(This is settable using git remote set-head origin ... to whatever branch you find convenient.)

    Hi. It makes a little bit more sense to me now but I am afraid I need more reading about remote branches, distributed git and git internals. Thanks – Celdor Mar 28 '17 at 7:34
