2 Let s Git Started part 2 In this mini tutorial we will quickly repeat what we told you about using GIT on your local machine GIT is a great tool when combined with an online repository and this is the topic of today! K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 2

3 Let s Git Started: what we have learned GIT is free, open source software. GIT Bash (Windows) git (Linux command line only) Command Line commands: Change directory: cd! List files in a directory: ls! Create a new directory: mkdir <name_of_dir>! K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 3

name "Your Name"! $ git config --global user.email i@me.

4 Let s Git Started: what we have learned Introduce yourself to GIT. $ git config --global user.name "Your Name"! $ git config --global user. i@me.com! K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 4

5 Let s Git Started: what we have learned Git keeps track of the changes of the files what we add to the index $ git add file1 file2! $ git add.! Git saves snapshots of the index $ git commit m I made this changes! K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 5

6 Using GIT: going on line! If you are not registered yet, please do so (every student should have an account, it s free!) An initial configuration is required. 1. Copy your SSH public key to your github account 2. Fork the report_template repository to my_repo 3. Configure it on line (rename, add team members) 4. Clone my_repo into your local drive 5. Push your first commit online K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 6

7 Using GIT: Step 1. SSH Keys What is an SSH public key? It is a certificate of your identity (actually of your laptop). Why do I need one? If you copy it and paste into your Github account, you don t have to reinsert username and password every time you connect with GIT K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 7

8 Using GIT: Step 1. SSH Keys To complete step 1 please follow one of the following tutorials: (it is basically the same process for all OS, only with a few changes) K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 8

9 Using GIT: Step 2. and 3. Forking and config Step 2, and 3 are done only by one group member, i.e. one repository for each group only! Click the Fork button at the top of this page: In the admin section of the forked project: Rename it using a significant name! Add your team members (collaborators) K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 9

10 Using GIT: Step 4. Clone project template Open GIT Bash. Type in one line: $ git clone git@github.com:my_username/my_project.git K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch

11 Using GIT: Step 3. Clone project template Open GIT Bash. Type in one line: $ git clone git@github.com:my_username/my_project.git K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 11

12 Using GIT: going on line! Step 4. Check that your local copy of the repo points to the correct online repository (your fork) $ git remote -v >> origin git@github.com:username/project.git (fetch) origin git@github.com:username/project.git (push) K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 12

13 Write your Research Plan and push it! Write your research plan inside the README file. When you are happy : $ git add README.md! $ git commit m Research Plan done! $ git push u origin master! K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 13

14 Using GIT: reminder! Be social: The person who created the repository has an admin panel on the repo page. Click Admin, then select Collaborators. Add the other group members (who should be so kind to tell you their user names ) Let us know about your group repo! Start following user msssm K. Donnay & S. Balietti / kdonnay@ethz.ch sbalietti@ethz.ch 14
