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.

Git Current Branch

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

Commands that need additional formatting without the formatting (base speed)

git branch	0m0.015s
git status	0m0.027s
cat .git/HEAD	0m0.004s
git symbolic-ref HEAD	0m0.007s
git name-rev HEAD	0m0.040s
