Git’s Native eMail Notifier

From the repository you wish to send email on commits.

cd .git/hooks
mv post-receive post-receive.bkp
ln -s /usr/share/git-core/contrib/hooks/post-receive-email post-receive
git config hooks.mailinglist "mailinglist@example.com"
git config hooks.emailprefix "[SUBJECT PREFIX] "  # note the trailing space

Git Commit Notifier

This ‘plugin’ will allow you to send an email every time a commit is committed to the repository. You may use this on the central repository to keep everyone following the project up to date.

• The source may also be downloaded at http://github.com/bitboxer/git-commit-notifier

To use this plugin, you first need to compile the script, then add the config information to each repository you wish to use it on.

To Install Git Commit Notifier

On Fedora 12 you first need to install Ruby and a few other dependences. After you download the needed dependences, you may compile the script.

yum install ruby rubygems hpricot rubygem-hpricott
gem install git-commit-notifier

To Configure Git Commit Notifier

In your repository’s .git/hooks folder or if it’s a “bare” repository, just the hooks folder. Create a file named post-receive with the following content.

#!/bin/sh
git-commit-notifier ../git-commit-notifier.yml

Once you have saved the file, you need to make it executable.

chmod 775 post-receive

After you have made the hook executable, check up one directory to the repository’s .git directory. From here you need to create and modify your git-commit-notifier’s config file. Start out by creating a file named git-commit-notifier.yml, and copy the below config to it.

Patches

Creating a patch

git diff file_with_changes > 0001-name_of_patch_file.patch
gzip 0001-name_of_patch_file.patch

Patching a file or directory

gzip -dc 0001-name_of_patch_file.patch.gz |patch -p1

Branching

Creating a new branch

git branch <branch>

or to create a branch and switch to it

git checkout -b <branch>

Pulling changes from branches

git checkout <branch_committing_to>

Now that your in the branch you want to add the changes to, run:

git pull . <branch_committing_from>

Changing to a different branch

git checkout <branch>

Deleting a branch

git branch -d <branch>

Deleting a remote branch

git push origin :<branch>

Pushing a branch to github

git push <remote_repository_name> <branch_name>

So that would be…

git push origin <branch>

Display branches on github

git remote show origin

Pulling a branch from github

git checkout --track -b <name_of_local_branch> origin/<name_of_remote_branch>

Tagging

Tagging a branch

git tag -a -m "tagging version 1.0" 1.0

Pushing the tag to github

git push --tags

Deleting a tag

git tag -d 1.0

Removing a deleted tag from github

git push origin :refs/tags/1.0

Submodules

To update existing submodules

git pull
git submodule init
git submodule update

To add a new submodule to a project

git submodule add <remote-host>:<project.git> <project.git>

So if you are adding project “program” from the example git server you will run

git submodule add git://example.com/program.git program

Creating an secure Git remote server

On the Server create the git repository

mkdir name-of-git-repo.git
cd name-of-git-repo.git
git init --bare

On the Client System create the git repo to import into the server

git init
touch README
git add README
git commit -m 'first commit'
git remote add origin git@REMOTE_SERVER:name-of-git-repo.git
git push origin master
