What is Git Checkout?
- This is the very useful command of git functionality which works three major components files, commits, and branches.
- It is the process that works to checking out previous commits and files in which the current working folder is updated to get equality on a selected branch.
- It’s an interchanging path on your currently active branch, as well as works to restore the files.
- It gives you permission to move on to your local branches. It’s not only restricted to the local branch but also applicable to create fresh new local branches through the remote branch.
- It’s mostly used to interchange on different branches and among them make one branch as a HEAD branch.
How to do git checkout?
- It is used to update head with the purpose of setting one specified branch as the current branch by using the command :
git checkout <branch>
- The next step is to work on that branch, you need to switch, with the help of updating index and files in your current working tree and points towards HEAD at that specified branch.
- If your working branch is not identified, but it is already present so to identify that branch in exactly one remote with its equivalent matching name is defined as :
git checkout –b <branch> –track <remote>/<branch>
- This will be done with a specific commit are as follows:
git checkout specific-commit-id
once above command runs, we are now able to get that specific commit id’s by using the command: git log .it will help you to checkout with specific commit.
- One more feature of git checkout functionality does a checkout with existing branch are as follows:
git checkout branch_name
considering the repository in which you are currently working which includes pre-existing branches. So git checkout helps you to switch between these branches.
- It’s also possible to do a checkout with a new branch by using one simple command as :
git checkout –b new branch_name.
if you want to add new features, then you may create a new branch of your master branch using the same command, which already executed in the above syntax. Once it created then you are now able to switch on this branch by using git checkout command.
git checkout –b <new_branch_name>
- Checking out branches: git checkout feature allows you to move among the branches which are created by using the command git
- The main function of this command is to keep updating all files in your working folder and able to match them with the version which is stored in that specific branch, which is responsible to record all new commits that came on that branch.
- Sometimes git checkout gets confused with git clone. But the difference between these two commands is that git clone is used to fetch code from its currently working remote repository where git checkout is used to switch among versions of code which are stored on your local system.
- Switching branches: it is one the feature of checkout which is used to indicating a pointer to HEAD to the <branchname>simply running a command as :
- Git stores a history of all detailed description of checkout command into the reflog
- Git checkout a Remote Branch: the main functionality of git checkout with a remote branch is to access the code from all your co-workers to better collaboration and review purposes.
- In the next step, when developer fixes bugs or update their codes, involve some new features then he or she will create a new branch to save all updates in safe mode rather than doing any changes to existing code.
- In this case, we don’t want to create a new local branch. so we will keep saving our changes on the remote version. So in this scenario, we are going to use the git checkout remote branch method.
- The first step while fetching git checkout remote branch is :
git fetch origin
- Next step is to check out the branch which you actually want :
git checkout –b branch_name origin/branch_name
- So with the help of this remote branch, all developer who is working on the same software, everyone is able to do their own changes in safe mode without adding any unnecessary or unstable code into the current working project.
- It provides the best feature of commit often in which, we are able to commit small and now capable to share whatever work done many times. It is the best way to avoid large merge conflicts.
- Try to avoid commit of unfinished work, into that once you finish your work verify it, and then commit all the changes. This is the most efficient method which avoids conflicts that occur during large merging. It also keeps one thing in mind that we are not going to commit small pieces of non-working code. Now don’t commit any code before actual testing is done on it. if we are sharing this code without testing that may create conflicts .so better way is to do testing on code and then commit changes.
- While running this command, first we need to check all the presented branches so we call the following command :
it will show a list of all the presented branches.
- Now we are creating a new branch:
git checkout –b checkout_demo
While running above command it will create a new branch named checkout_demo and with the help of the checkout function, it switches to a newly created branch.
- Next step is to fetch all data by using git fetch
- Now we are checking with the existing branch
- The remote branch :
It will help you to check out the new local branch by updating all changes to the remote branches’ commit process.
- All the above contents conclude that it is used to switch in between active branches and other stored branches.
- This functionality is used to create new branches, switch branches and checkout with remote branches.
- It also updates the head to set a specified branch as a current branch.
