Setting up a Git projecthttp://git.or.cz/gitwiki/QuickStart If you want to work with an existing project, clone it:
$ git clone If you do not have an existing git project, create one:
$ cd project/ $ git init # initializes the repository
$ git add . # add those 'unknown' files
$ git commit # commit all changes, edit changelog entry
Git will look for a file named .gitignore in the root of your repository which contains a set of shell patterns to ignore in file paths.
Branching and merging$ git checkout -b linux-work # create a new branch named "linux-work" $
$ 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)
Importing patches$ git apply < ../p/foo.patch $ git commit -a
Exporting a patch$ $ 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)
Network support# clone from the primary Git repo foo$ git clone git://git.kernel.org/pub/scm/git/git.git
foo$ cd git
# pushing changes to a remote repo with SSH
foo$ git push user@example.com:my-repository.git/
# fetch changes to a remote branch into a local branch
foo$ git fetch user@example.com:my-repository.git/ remote-branch:local-branch
# merge changes from a remote machine
bar$ git pull git://foo/repo.git/ branch
# Serve repository via git protocol
foo$ cd /my/repository/
foo$ touch .git/git-daemon-export-ok
foo$ git daemon # now others can fetch from git://your.machine/my/repository/.git/
# Set up a bare (= without working directory) repository (e.g. on a webserver)
foo$ mkdir my-repo.git
foo$ cd my-repo.git
foo$ git --bare init
foo$ chmod a+x hooks/post-update # this is needed for HTTP transport
# you need to populate this repository via push
Inspecting revisions# inspect history visually foo$ gitk # this opens a Tk window, and shows you how the revisions are connected
# inspect history
foo$ git log # this pipes a log of the current branch into your PAGER
foo$ git log -p # ditto, but append a patch after each commit message
# inspect a specific commit
foo$ git show HEAD # show commit info, diffstat and patch
# of the tip of the current branch
Referring to revisions# by name foo$ git log v1.0.0 # show history leading up to tag "v1.0.0"
foo$ git log master # show history of branch "master"
#> foo$ git show master^ # show parent to last revision of master
foo$ git show master~2 # show grand parent to tip of master
foo$ git show master~3 # show great grand parent to tip of master (you get the> # by output of "git describe"
foo$ git show v1.4.4-g730996f # you get this string by calling "git describe"
# by hash (internally, all objects are> foo$ git show f665776185ad074b236c00751d666da7d1977dbe
foo$ git show f665776 # a unique prefix is sufficient
# tag a revision
foo$ git tag v1.0.0 # make current HEAD known as "v1.0.0"
foo$ git tag interesting v1.4.4-g730996f # tag a specific revision (not HEAD)
Comparing revisions# diff between two branches foo$ git diff origin..master # pipes a diff into PAGER
foo$ git diff origin..master > my.patch # pipes a diff into my.patch
# get diffstat of uncommitted work
foo$ git diff --stat HEAD
Cherry picking patchesfoo$ git cherry-pick other-branch~3 # apply 4th last patch of other-branch to current branch
