If you want git not to commit some temporary files or log files...etc., you could create .gitignore file to ignore them. If you don't have any idea about which file should be ignore, you could also download ignore templates that prepared by github. mkdir ~/git-home cd ~/git-home git init git clone https://github.com/github/gitignore cd ~/my_py_project cp ~/git-home/gitignore/Python.gitignore ./.gitignore Wish this helps. regards, Stanley Huang
