output to a file:
git log > filename.log
git log --pretty=format:"%s" --since=15.weeks > aaaa.log
To specify a format, like you want everything on one line
git log --pretty=oneline >filename.log
or you want it a format to be emailed via a program like sendmail
git log --pretty=email |email-sending-script.sh
to generate JSON, YAML or XML it looks like you need to do something like:
git log --pretty=format:"%h%x09%an%x09%ad%x09%s"
This gist (not mine) perfectly formats output in JSON:https://gist.github.com/1306223
