I'm looking for a command to execute against my git repo to discover the amount of code changed in a certain period of time.
I want to know how much code was changed since day 'X'. I don't really care about the percentage of code changed by each author.
You can use the --stat option of git diff.
For instance
git diff --stat HEAD HEAD~1 will tell you what changed from the last commit, but I think what's closest to your request is the command
git diff --shortstat HEAD HEAD~1 which will output something like
524 files changed, 1230 insertions(+), 92280 deletions(-) EDIT
Actually I found this great answer that addresses the same issue much better that I can do.
This is me line is changed to this is me in the new commit. Is there a way to get the no of lines modified in a repo between commitsFollowing up the excellent answer Gabriele found, the exact command you need is:
git log --since=31/12/2012 --numstat --pretty="%H" | awk ' NF==3 {plus+=$1; minus+=$2;} END {printf("+%d, -%d\n", plus, minus)}' (yes, you can paste that onto a single line, but the answer's more readable like this)
The key difference is the in a certain period of time requirement, handled by the --since argument.
DD/MM/YYYY, and YYYY-MM-DD also works.
--no-merges flag in the git log to avoid duplicates?As a less awksome alternative:
REV=$(git rev-list -n1 --before="1 month ago" master) git diff --shortstat $REV..master The "before" date can of course be a more standard representation of time as well.
