Short introduction to git
In general, you can find a good documentation on the use of git on this website:
How to do submodules
adding a submodule to git
$ git submodule add git@bitbucket.org:tkroeger/lwr.git 3rdparty/lwr
$ git status
$ git commit -m 'first commit with submodule lwr'
$ git log -1 $ cd 3rdparty/lwr/ $ git log -1
Cloning a Project with Submodules
$ git clone git://github.com/schacon/myproject.git
$ git submodule init $ git submodule update
This is the case because the pointer you have for the submodule isn’t what is actually in the submodule directory. To fix this, you must run git submodule update again:
$ git submodule update
You have to do this every time you pull down a submodule change in the main project. It’s strange, but it works.

Getting started
Navigate to your git repository:
cd scl-manips-group/
The status command shows you on which branch you are currently on. It also shows you, what changes have not been staged or tracked yet:
git status
Now run
git pull
to update your repository from the remote source.
To see the branching structure:
git branch -a
Create a new branch:
git branch <your name>
To activate the branch:
git checkout <your name>
To upload branch to bitbucket:
git push origin <your name>
Create a new temporary working branch:
git branch <your name>-workspace git checkout <your name>-workspace
Delete local branch (to setup a tracking branch):
git branch -D <your name>
Checkout remote branch again with tracking:
git checkout --track -b <your name> origin/<your name>
If you are on the 'master' branch, start a new, personal branch to work on:
git branch <your-name>
for example my branch is called
git branch robert
With this command you push your files to your new branch:
git push origin robert
The branch command should show you now, that you have generated a new branch:
git branch
but you have not checked it out, since there is no star next to it, so you need to do so in order to work on the new branch:
git checkout robert
git branch -a
cat .git/config
ls
git checkout master
git branch -D robert
git branch --track robert origin/robert
git branch -a
git checkout robert
git branch -a
