Repository creation

1. Create a directory for the information to be under version control

   mkdir myProject

2. Open the directory

   cd myProject

3. Initiate an empty repository

   git init

4. Add current files to the repository

   git add .

5. Commit the changes to the repository

   git commit -m "message with a brief description of the changes"

Remote repository creation

1. Login in the external server via ssh

   ssh username@server-host

2. Go to repository directory

   cd /var/repo

3. Create a directory for the information to be under version control

   mkdir myProject.git

4. Open the directory

   cd myProject.git

5. Initiate an empty shared bare repository

   git --bare init --share=group

Mirroring to a remote server

1. Add the external repository

   git remote add origin ssh://username@server-host/var/repo/myProject.git

2. Push the local files to the repository

   git push origin master

mirroring to the web server

1. Create a mirror of a bare repository

   git clone --mirror ssh://username@server-host/var/repo/MyProject.git

2. Update the local content

   git fetch -q --all

Clone a git project

1. Go to the directory where the project will reside, in this example workspace

   cd workspace

2. Clone the external project

   git clone ssh://username@server-host/var/repo/myProject.git myProject

Working with git

1. Change the directory to the project directory, in this case inside workspace directory

   cd workspace/myProject

2. Obtaining the last committed changes

   git pull

3. Submitting the local changes to the co-workers
4. Adding files and modification

   git add .

5. Committing to the local version

   git commit -m "Message that describe the changes in the project"

6. Pushing the changes in the external repository

   git push

Branching Git Repository

The next instructions were taken from the GIT-SCM Branching

1. Create a new branch

   $ git branch MyBranch

   where MyBranch is the branch to create

2. Switch to an existing branch, you run the git checkout command. Let’s switch to the new MyBrnach branch:

   $ git checkout MyBranch

3. A short instruction to create a branch and change to it as a working copy is:

   $ git checkout -b MyBranch

4. To switch between branches: (in this case to the master or trunk)

   $ git checkout master

5. To merge a branche with the master:

   $ git checkout master

   $ git merge MyBranche

6. Now you are ready to delete the merged branche:

   $ git branch -d MyBranche

7. To push a branche in the repository

   $ git push -u origin MyBranche

8. To checkout a branch from the repository

   $ git checkout -b MyBranche origin/MyBranche
