Usecases using git log

ref:http://dev-logger.blogspot.sg/2009/05/usecases-using-git-log.html

Usecase: I want to be up to date with the latest activity

git log

git log -4

git log --since="1 day"

git log --since="2 hour"

git log -2 --stat

git log -2 --name-status

git log --since='2009-05-05' --until='3 days'

git log i-2 --author='Martin C'

git log 9485fdd2..7b766227 # optionally specify a file

Usecase: I want the latest changes on a specific file

git log [file] # gives you all commits for that specific file

git log -3 [file] # gives you the 3 last commits

git log -p [file] # gives you all diffs for every commit of that file

git log -2 -p db/schema.rb

git blame [file] # gives SHA1, author, line changed, app/controllers/questions_controller.rb

Usecase: I want the changes of a commit you partly remember the comment

git log --pretty=oneline | grep [comment

git log --grep='^user icon'

git log --grep='user icon' -i

git show [SHA1]

git show [SHA1]:[file

Usecase: I want stats on commits

git log --pretty=oneline | wc -l

git log --pretty=oneline --no-merges | wc -l  # no-merges: do not show commits that have more than 1 parent

git log --pretty=oneline --author='Martin C' | wc -l

git log --pretty=format:'%an' | sort | uniq -c | sort -n

git log --pretty=format:'%h by %an'

git log -4 --pretty=format:'%h (%H) by %an %ar (%ad) %s'

git log -4 --pretty=format:'%h by %an %ar (%ad) %s' db/schema.rb
