Introduction to Git

A version control system, like CVS, SVN, Perforce or ClearCase. Contrary to CVS or SVN, Git is a distributed version control System.

-No central repository

-Everybody has a local repository

-Local branches are possible, and very important

-Easy exchange of code between developers

-Well-suited to the collaborative development model used in open source projects

sudo apt-get install git-core

git config --global user.name 'My Name'

git config --global user.email me@mydomain.net

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

git log -p will list the commits with the corresponding diff

git log v2.6.30..master

git log v2.6.29..v2.6.30 MAINTAINERS

git pull:

-Fetch the new changes from the remote repository (git fetch)

-Merge them in the current branch (git merge)

git tag -l

git checkout <tagname>

git status

git checkout -b <branchname> (git branch <branchname> + git checkout <branchname> )

git branch -l

git branch -a

Git has a feature called the index, which allows you to stage your commits before committing them. It allows to commit only part of your modifications, by file or even by chunk

On each modified file: git add <filename>

Then commit. No need to be online or connected to commit: git commit

If all modified files should be part of the commit: git commit -a

First step is to generate the patches: git format-patch -n master..<yourbranch>

Will generate one patch for each of the commits done on <yourbranch>

The patch files will be 0001-...., 0002-...., etc.

Second step is to send these patches: git send-email --compose --to email@domain.com 00*.patch

Create a bare version of your repository

cd /tmp && git clone --bare ~/project project.git && touch project.git/git-daemon-export-ok

Transfer the contents of project.git to a publicly-visible place (reachable read-only by HTTP for everybody, and read-write by you through SSH)

Tell people to clone http://yourhost.com/path/to/project.git

Push your changes using: git push ssh://yourhost.com/path/toproject.git srcbranch:destbranch
