The point is, your development should always take place on a branch-never on a detached HEAD. When you inevitably check out another branch (e.g., to merge your feature in), there would be no way to reference your feature: If you were to start developing a feature while in a detached HEAD state, there would be no branch allowing you to get back to it. This is a warning telling you that everything youвЂ™re doing is вЂњdetachedвЂќ from the rest of your projectвЂ™s development. When it points to a branch, Git doesn't complain, but when you check out a commit, it switches into a вЂњdetached HEADвЂќ state. Internally, the git checkout command simply updates the HEAD to point to either the specified branch or commit. Remember that the HEAD is GitвЂ™s way of referring to the current snapshot. Now that weвЂ™ve seen the three main uses of git checkout on branches, it's important to discuss the вЂњdetached HEADвЂќ state.

Usage: Existing branchesДЄssuming the repo you're working in contains pre-existing branches, you can switch between these branches using git checkout.

The difference between the two commands is that clone works to fetch code from a remote repository, alternatively checkout works to switch between versions of code already on the local system. The git checkout command may occasionally be confused with git clone. In addition, branches also facilitate several collaborative workflows. It makes it ridiculously easy to try new experiments without the fear of destroying existing functionality, and it makes it possible to work on many unrelated features at the same time. Having a dedicated branch for each new feature is a dramatic shift from a traditional SVN workflow. Think of it as a way to select which line of development youвЂ™re working on. Checking out a branch updates the files in the working directory to match the version stored in that branch, and it tells Git to record all new commits on that branch.

The git checkout command lets you navigate between the branches created by git branch. The focus for the majority of this document will be checkout operations on branches.Д¬hecking out branches is similar to checking out old commits and files in that the working directory is updated to match the selected branch/revision however, new changes are saved in the project history-that is, itвЂ™s not a read-only operation. In the Undoing Changes topic, we saw how git checkout can be used to view old commits. In addition to the definition of 'checkout' the phrase 'checking out' is commonly used to imply the act of executing the git checkout command. The git checkout command operates upon three distinct entities: files, commits, and branches. In Git terms, a 'checkout' is the act of switching between different versions of a target entity. It will cover usage examples and edge cases. Once you've done that, you'll be switched to the HEAD of your new branch and you can continue working as normal, or switch to another branch as required.This page is an examination of the git checkout command. This is necessary because the branch doesn't exist on the remote and we need to be able to track further changes to it.

Notice that we've added the -set-upstream origin my_new_branch switch to the command. * my_new_branch -> my_new_branchД«ranch 'my_new_branch' set up to track remote branch 'my_new_branch' from 'origin'. Remote: Create a pull request for 'my_new_branch' on GitHub by visiting: Switched to a new branch 'my_new_branch' $ git push -set-upstream origin my_new_branch
