In the version WithdrawCommit section of the chapter BasicsKnowledge, you already know that for each commit, Git strings them together into a timeline, and this timeline is a branch. As of now, there is only one timeline. In Git, this branch is called the master branch, that is, the master branch. Strictly speaking, HEAD does not point to the commit, but to the master, and the master points to the commit, so HEAD points to the current branch.
Therefore, creating branches, switching branches, and deleting branches are only operations on the corresponding pointers, so the speed will be very fast.
We noticed that
git checkout <branch> is used to switch branches, while the previously mentioned undo changes are
git checkout -- <file>. The same command has two functions, which is indeed a bit confusing.
In fact, the action of switching branches is more scientific with
switch. Therefore, the latest version of Git provides a new git switch command to switch branches. Using the new git switch command is easier to understand than git checkout.
git: 'switch' is not a git command Because this command is released in version
