count total commits on current branch - 统计当前分支的提交数

count-git-commits.sh

git log | grep -e 'commit [a-zA-Z0-9]*' | wc -l
# 不准确，如果提交信息里有commit ...字样也会计算进去

# UPDATE:
git log --oneline | wc -l

# UPDATE 2:
# get the commit count for a revision (HEAD, master, a commit hash)
git rev-list --count <revision>
# get the commit count across all branches
git rev-list --all --count
