When git deletes a branch, it prompts that there are sub-branches

In recent years, Git, as an extremely important code management tool, has been widely used in software development. It allows programmers to easily manage branches, merge code, and perform version control. However, we often encounter some problems when operating Git. For example, this article will discuss the problem of GIT deleting a branch and prompting that there are sub-branches.

Git deletion of branches can usually be achieved by using the command "git branch -d branch name". However, sometimes we will receive the following prompt:

error: The branch 'subbranch name' is not fully merged.

If we continue to execute "git branch -d branch name" ”, you will receive the following error message:

error: Cannot delete the branch 'branch name' which you are currently on.

This means that we need to switch to other branches first, and then Then delete this branch. However, if you no longer need this branch, you can try to forcefully delete the branch, that is, "git branch -D branch name".

However, there may be some sub-branches that have not been merged into the branch we want to delete above. In this case, the system will prompt: "Has not been fully merged". At this time, you need to merge the sub-branch first and then delete the branch.

Below, we take branch A as an example to introduce how to solve this problem.

First of all, we need to check the current branch status. Use the command "git branch -av" to check the status of all local branches, including branch name, branch, last submitted comments and other information.

Next, we need to merge the sub-branches. Use the "git merge subbranch name" command to merge subbranches. Then use the "git branch -d branch name" command again to successfully delete the specified branch.

However, if you encounter conflicts when merging branches, you need to use the "git status" command to view the conflicting files, then manually modify the code, then run the "git add" command to add the changes, and finally run " git commit" to submit the changes.

In addition, if you delete a branch and find that you deleted it by mistake, you can use the "git reflog" command to view all operations performed, and then use the "git checkout" command to roll back to the required version. If you need to restore a deleted branch at the same time, you can use the "git branch branch name commit_ID" command to create a new branch and restore it to the state when it was deleted.

In short, when Git deletes a branch, it prompts that there are sub-branches, which requires us to perform certain operations to merge sub-branches and delete specified branches. In the actual development process, we need to pay attention to branch management to avoid similar problems. Only by using branch management correctly and reasonably can we get twice the result with half the effort during the development process.
