Git is a very popular distributed version control tool. It can help us manage the modification history of the code and help us collaborate to develop and maintain the code.
In the process of using Git for development, we often need to modify the history of the code, such as modifying submission information, merging branches, etc. This article will introduce the methods and precautions for Git modification history.
1. Modify the latest submitted information
When using Git for development, you need to write the submission information every time you submit the code. However, sometimes there may be errors or missing information due to various reasons, in which case the submission information needs to be modified.
We can use the Git command git commit --amend to modify the latest commit information. The specific operations are as follows:
git commit --amend
At this time, our most recently submitted information has been modified.
2. Modify the information of a certain submission in the history record
Sometimes it may be necessary to modify the information of a certain submission in the history record, such as to better record the update history, or to avoid Misunderstandings and other reasons. The specific operation is as follows:
git rebase -i HEAD~n
where n represents the number of commits before the commit you need to modify. , for example, n=5 means you need to modify the information submitted in the sixth to last submission.
git commit --amend
3. Merge submission history
The purpose of merging submission history is to make our historical records clearer and avoid too many useless submission records. The specific operations are as follows:
git rebase -i HEAD~n
where n represents the previous commit of the commit history that you need to merge Number of submissions.
Note:
Summary
Through this article, we learned how to modify the history of Git. Whether we are modifying the information of the latest commit, modifying the information of a certain commit in the history, or merging the commit history, we need to ensure the correctness and prudence of the operation as much as possible to avoid unnecessary trouble.
