Git via github.com

---

1. Github.com

• create a repository at github
• copy the link for cloning a repository
• locally type git clone <git_URL>
• get updates via git pull inside the git repository

1.1 Local Repository

step by step

• use git init to create a git directory in any directory you want
• this is the master directory, so every sub directory is included
• at github, follow the description to link it to your local folder
• gitstatus always tells you what to do
• you add things you want to commit using git add <file>
• git commit -m "message" to commit your changes
• git push origin master pushes commited file to internet git repository
• git pull to get a update from github
• nano .gitignore write filenames in .gitignore that you don't want to be added or pushed

1.2 Installing Gits

• Download and compile new programs or git clones into ~/install/
• then put the path to ~/.bashrc: b # do nano ~/.bashrc and add export PATH="/home/replik/install/canu/Linux-amd64/bin:$PATH"
• Search the programs in github
• the make or configure steps are written there or in the README.md. Do a make clean if you get errors during make before doing a new make

1.3 Git sides

• this is basically a website hosted via github
• all files are maintained via the master
• can be easily created with mkdocs
• see this side

2. Branching

• on a local master do
• creates the branch "testside"

# create a branch
git checkout -b testside
# Edit, add and commit your files.
git push -u origin testside

# commiting and push normally but use this:
git push origin testside # not master

• merging branch with master

# change to the master branch
git checkout master
# merge the testside branch INTO the master
git merge testside
# push the new master to github
git push origin master
# cheange back to testside via
git checkout testside

3. Working with ssh keys

a) create key via ssh-keygen -t rsa -b 4096 -C "your_email@domain.com" if you dont have one b) copy the *.pub key to github.com (account - settings - ssh und gpg keys) c) do nano ~/.ssh/config and add

host github.com
 HostName github.com
 IdentityFile ~/.ssh/id_rsa
 User git

d) chmod 660 .ssh/config

• you need to clone with ssh not http on github.com (small button at the clone window)

# looks like this
git clone git@github.com:nanozoo/bx_guppy_gpu.git

e) change http to git@

git remote set-url origin git@github.com:USERNAME/REPONAME.git
