Number of commits per year

# Echo number of GIT commits per year.
git log --pretty='format:%cd' --date=format:'%Y' | uniq -c | awk '{print "Year: "$2", commits: "$1}'

Does this include all branches or only the master/default branch?

@olleharstedt It seems this refers to branch which you have checkouted.

@lordt Yes. I've added --all to include all branches. Thank you.

Heh, nice to see this is useful to someone else, too. :)
