These benchmarks aim to show the fastest way to get information from git. Getting fast git info is particularly important if you are trying to add information to the PS1 property of a terminal. All the tests are conducted in the git repo and are the fastest of 5 executions.
The fastest way to get a git repo's current branch is: cat .git/HEAD | awk -F refs/heads/ '{ print $2; }'
Try it yourself!
$ curl -sSL https://github.com/jareddlc/git-gud/raw/master/git-branch-current.sh | sh
