Don't add untested features to main branch!

Commands¶

git init = create a new repo
touch {file} = creates an empty file if a file does not exist.
git add {file} = tells git to stage the file or directory for a commit, if it exists.
git status = displays the state of the working directory and the staging area
git commit -m "Message" = Commit the files in staging to the repository; include a description message using the –m flag
git rm {file} = remove file from the working directory
git checkout HEAD {file} = get the deleted file back; HEAD is a pointer to your most recent commit. This could also be the SHA value of any previous commit.
git diff = see changes
git diff --cached {file} = see the difference between the staged version and the repository version, specify the --cached flag
git branch = list all current branches; current branch marked with *
git branch {branchName} = create new branch
git checkout {branchName} = switch branch
git checkout -b {bName} = created the branch and switched to it in one command by specifying the -b flag to git checkout.
git merge {bName} = merge the branch to current branch
git branch -d {bName} = delete the branch
git push -f: Force a push that would otherwise be blocked, usually because it will delete or overwrite existing commits (Use with caution!)
git push -u origin [branch]: Useful when pushing a new branch, this creates an upstream tracking branch with a lasting relationship to your local branch
git push --all: Push all branches
git push --tags: Publish tags that aren't yet in the remote repository
