Concise Listing of Git use cases
git show c82aa23 (the commit)
git show foobranch (tip of the foobranch branch)
git show HEAD (tip of current branch)
git show HEAD^ (parent of head, previous state of the project)
git show HEAD~1 (same as HEAD^)
git show HEAD (grandparent)
git show HEAD~2 (same as HEAD)
To see whether a particular commit is in a particular branch:
git log --pretty=one <branch> | grep sha1
Sets of commits
git log v2.5..v2.6 # commits between v2.5 and v2.6
git log v2.5.. # commits since v2.5
git log --since="2 weeks ago" # commits from the last 2 weeks
git log v2.5.. Makefile # commits since v2.5 which modify Makefile
Commits where one is not an ancestor of the other
If the tips of the branches "stable-release" and "master" diverged from a common commit some time ago, then
git log stable..experimental
will list commits made in the experimental branch but not in the stable branch, while
git log experimental..stable
will show the list of commits made on the stable branch but not the experimental branch.
Merging, etc
git pull /home/bob/myrepo master # merge changes from bob's master branch onto my current branch
(pull fetches and merges)
git fetch /home/bob/myrepo master
git log -p HEAD..FETCH_HEAD
(two dot form - 'everything reachable from FETCH_HEAD, excluding anything reachable from HEAD') or
gitk HEAD...FETCH_HEAD
(three dot form - 'show everything reachable from either, exclude anything reachable from both) (fetch and look at everything between HEAD and head of what bob had)
Using remote repositories
git remote add bob /home/bob/myrepo
git fetch bob
git log -p master..bob/master # list of changes since bob branched from my master
git merge bob/master # merge changes in bob into my master branch
git pull . remotes/bob/master # same as the last one
(git pull always merges into the current branch)
git push --tags remotename localbranch:remotebranch
(creates remote branch)
rebasing
git rebase master topic # place all new commits in topic on top of master
Assorted
gitk --since="2 weeks ago" drivers/
git diff v2.5:Makefile HEAD:Makefile.in # diff different files in different commits
git reset --hard HEAD - throw away all changes
git reset --hard HEAD^ - throw away the last commit that was made
git grep "foo" existingtagname
git diff tagname HEAD
git branch newbranchname existingtagname
Accessing remote branch lpia
git clone --reference /home/sconklin/src/reference-trees/linus git://kernel.ubuntu.com/ubuntu/ubuntu-hardy.git hardy-kernel
git checkout origin/lpia
