git modifies specified commit information

In the process of using Git for version control, we will inevitably encounter situations where we need to modify the submission information that has been submitted. This may be because we wrote the wrong information when submitting, or we need to add additional explanations to the submitted code, etc.

Next, we will introduce in detail how to use git to modify the specified commit information, as well as some matters that need to be paid attention to.

1. Use git commit --amend to modify the specified submission

If we miss some files when submitting, or need to modify the submitted files, you can use git commit - -amend command to modify the specified commit information.

The specific steps are as follows:

1. Execute the git log command to find the commit record ID that needs to be modified.
2. Execute the git rebase -i HEAD~n (n is the number of commits that need to be modified) command to enter interactive mode.
3. Press the i key to enter editing mode.
4. Change the pick of the submission record ID that needs to be modified to edit, save and exit.
5. Execute the git reset HEAD^ command to roll back to the previous commit.
6. Perform operations such as modifying or adding files.
7. Execute the git add command to add the modified file to the temporary storage area.
8. Execute the git commit --amend command to modify the submission information.
9. Execute the git rebase --continue command to complete the modification of the submission information.

2. Use git filter-branch to modify the specified submission

If we need to adjust a large amount of submission information, or the operations performed are more complex, we can use the git filter-branch command to modify the specified submission Submit Information.

The specific steps are as follows:

1. Execute the git log command to find the commit record ID that needs to be modified.
2. Execute the git filter-branch --tree-filter command, and add the operations to be performed after it, such as:

git filter-branch --tree-filter 'rm -f file.txt' HEAD

This means deleting the file file.txt. If you need to modify the submission information, you can execute the following command:

git filter-branch --msg-filter 'sed "s/old_text/new_text/g"' HEAD

3. Execute the git push --force command to push the modified information to the remote branch.

3. Things to note

1. Modifying the submission information will change the SHA-1 code value of the submission, which may cause the branches referenced in the repository to appear. question.
2. If you have pushed the local branch to the remote branch, you need to use the git push --force command to force the modified submission information to be pushed, which may affect the repositories of other collaborators.
3. It is recommended to create a backup before modifying the submission information to prevent unnecessary errors.
4. Be careful when using the git filter-branch command to make modifications. If the operation is not standardized, it may affect other submitted information.

In short, modifying the submission information is a relatively complex operation, and it needs to be done carefully while ensuring data security to avoid unnecessary problems.
