Working with Git
Quick Start
git clone <url> # Clone directory
git checkout -b <new-branch> # Create new local branch
git push -u origin <new-branch> # Sync local branch with remote
git checkout <branch> # Checkout branch
git push origin <branch> # Push branch to remote
git commit -a --allow-empty-message -m '' # Push without commit
git branch -d <branchname> # deletes local branch
git push origin :<branchname> # deletes remote branch
git subtree push --prefix docs origin gh-pages # push docs as subtree to gh-pages
Clone Directory
git clone <url>
Create Project
cd project/
git init # initializes the repository
git add . # add those 'unknown' files
git commit # commit all changes, edit changelog entry
git rm --cached <file>... # ridiculously complicated command to undo, in case you forgot .gitignore
### Branching and Merging
git branch # show list of all branches (* is active)
git checkout -b linux-work # create a new branch named "linux-work"
<make changes>
git commit -a
git checkout master # go back to master branch
git merge linux-work # merge changesets from linux-work (Git >= 1.5)
git pull . linux-work # merge changesets from linux-work (all Git versions)
git branch -m <oldname> <newname> # rename branch
git branch -m <newname> # rename current branch
git remote -v # Get list of remote branches
git remote add upstream <upstream github url> # Add original as upstream
git remote -v # Check upstream
git fetch upstream # Get original repo
git checkout development # Switch to main branch in local fork
git merge upstream/development # Merge original with fork
git diff --name-only | uniq | xargs subl # Fix conflicts in Sublime Text
### Importing Patches
git apply < ../p/foo.patch
git commit -a
Exporting Patches
git commit -a -m "commit message"
git format-patch HEAD^ # creates 0001-commit-message.txt
# (HEAD^ means every patch since one revision before the
# tip of the branch, also known as HEAD)
Inspecting Revisions
inspect history visually
gitk # this opens a Tk window, and shows you how the revisions are connected
inspect history
git log # this pipes a log of the current branch into your PAGER
git log -p # ditto, but append a patch after each commit message
inspect a specific commit
git show HEAD # show commit info, diffstat and patch
# of the tip of the current branch
Referring to Revisions
by name
git log v1.0.0 # show history leading up to tag "v1.0.0"
git log master # show history of branch "master"
relative to a name
git show master^ # show parent to last revision of master
git show master~2 # show grand parent to tip of master
git show master~3 # show great grand parent to tip of master (you get the idea)
by output of "git describe"
git show v1.4.4-g730996f # you get this string by calling "git describe"
by hash (internally, all objects are identified by a hash)
git show f665776185ad074b236c00751d666da7d1977dbe
git show f665776 # a unique prefix is sufficient
tag a revision
git tag v1.0.0 # make current HEAD known as "v1.0.0"
git tag interesting v1.4.4-g730996f # tag a specific revision (not HEAD)
Comparing Revisions
diff between two branches
git diff origin..master # pipes a diff into PAGER
git diff origin..master > my.patch # pipes a diff into my.patch
get diffstat of uncommitted work
git diff --stat HEAD
Sublime as default text editor
cd ~
mkdir bin
ln -s "/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl" ~/bin/subl
git config --global core.editor "subl -n -w"
