Assuming you have already cloned a repository, the best place to start is with:
This will show the current state of the files including the branch you are on and any untracked changes. If you’ve come back to a project after a few days off, this will remind you where you are (which branch) and what you were doing (un-committed changes and diffs).
‘git status’ may show modified files, such as:
On branch master Your branch is ahead of 'origin/master' by 3 commits. (use "git push" to publish your local commits) Changes not staged for commit: (use "git add <file>..." to update what will be committed) (use "git checkout -- <file>..." to discard changes in working directory) modified: ../../../src/apps/sequencer/engine/generators/RandomGenerator.cpp no changes added to commit (use "git add" and/or "git commit -a")
To find out what is different in your changed files, type:
git diff ../../../src/apps/sequencer/engine/generators/RandomGenerator.cpp
If your diff output is formatted incorrectly (escape codes instead of colors), try:
git config --global core.pager "less -R"
To show all branches:
git branch -a
To create a new branch:
git checkout -b <NEW BRANCH NAME>
To change to a new branch:
git checkout <branch name here>
To change back to the “default” branch :
check checkout master
To delete a branch:
git branch -d <branch_name>
To commit your changes
git commit -m "comment here"
Upload your changes to github
git push --set-upstream origin <your-branch-name-here>
