How to Detect the Default Branch in a git Repository
Over the past few years, many engineering teams have switched their default git branch name from master to a different, potentially less offensive term. I'm all for choosing to name your default branch whatever you'd like, but not having a universal default branch name can complicate some automation.
So how can we detect the default branch name for a git repository? I use a few chained commands:
git remote show REMOTE_REPO_NAME | grep 'HEAD branch' | cut -d' ' -f5
Swap out REMOTE_REPO_NAME with the name of the remote/ upstream repository and you'll get the remote repository's default branch name!

I work with an awesome cast of developers at Mozilla, and one of them in Daniel Buchner. Daniel's shared with me an awesome strategy for detecting when nodes have been injected into a parent node without using the deprecated DOM Events API.
![Regular Expressions for the Rest of Us]()
Sooner or later you'll run across a regular expression. With their cryptic syntax, confusing documentation and massive learning curve, most developers settle for copying and pasting them from StackOverflow and hoping they work. But what if you could decode regular expressions and harness their power? In...

Image protection is a hot topic on the net these days, and why shouldn't it be? If you spent two hours designing an awesome graphic, would you want it ripped of in matter of seconds? Hell no! That's why I've created an image...
![Unicode CSS Classes]()
CSS class name structure and consistency is really important; some developers camelcase classnames, others use dashes, and others use underscores. One thing I've learned when toying around by HTML and CSS class names is that you can actually use unicode symbols and icons as classnames.
Cool trick ! Except… it works only if your LANG is “en”…

How to find default branch for all the repositories in an organization ?
Hi, thanks for it!
I digged a bit further on git remote and I noticed in its man page the subcommand git remote set-head. Its description begins with “Sets or deletes the default branch (i.e. the target of the symbolic-ref refs/remotes//HEAD)”.
So, it turns out that we can actually do this:
$ sed -e ‘s/^.*\///’ < .git/refs/remotes/origin/HEAD
devel
It is way faster than actually querying the remote server.
