Study Notes

Git Workflow Commands

git add: Copies data from the working area to the index. Does not change the repository. Overwrites previous versions of the file in the index.
git commit: Copies data from the index to the repository. Creates a new commit, updates the branch, and modifies the repository beyond just copying the file.

Moving Data to the Left

git switch (or git checkout): Moves data from the repository to the working area and index . Changes the HEAD reference to a new commit, effectively changing the current commit. To move to another commit on a branch, use git switch. Does modify the repository by updating HEAD.

Removing Files

git rm: Deletes files. Without --cached, git rm removes a file from both the working directory and the index. If the file isn't in the repository, Git warns that changes will be lost, offering a --force option for immediate deletion or --cached to only remove from the index.
- --cached is critical; it removes a file ONLY from the index, leaving it in the working directory.

Renaming Files

git mv: Renames files in the working area and updates the index. Git automatically tracks renames and moves if the file content is unchanged. This is a convenience command, and a manual approach (add, then commit) is not incorrect.
