  14. GIT architecture

  15. gitconfig --global user.name "Your Name" gitconfig --global user.email "your_email@whatever.com"

  16. add/reset/commit: move files from working-dir to stage-dir(aka index) git add . git add src/. git add src/lec01/glab/DigitalToBinary.java move files from stage-dir(aka index) to working-dir git reset HEAD . git reset head src/. git reset head src/lec01/glab/DigitalToBinary.java git commit -m “your commit message.”

  17. Amending: Every commit is associated with a sha-1 hash. That hash is derived from 1/ the file changes in that commit and 2/ the previous commit. You can not change any commit unless that commit is at the head. Since no other commits depend on the head, you may safely change the head. To change the head, use git commit --amend -m “your message” git commit --amend --no-edit

  18. Reverting: You can roll back a commit (reverse it) by identifying it's sha1 hash like so. git revert --no-edit 71ac

  19. Branching: To list the branches in a project: git branch git branch -r git branch --all To create a branch: git checkout -b branchName c39b git checkout -b branchName To delete a branch: git branch -D branchName To checkout a branch: git checkout 7afe git checkout master

  20. Pushing to remotes: To see the remotes: git remote -v show To push to a remote: git push origin master:master git push origin master git push --all

  21. Pulling from remotes: To see the remotes: git remote -v show To pull from a remote: git pull --all git pull origin eval

  22. NetBeanskeymap
