git change version description

Git is currently the most popular version control tool. It can help developers collaborate, track code modifications, and restore erroneous code modifications. In Git, version description records important information for each submission, including the content, reason, and author of the code modification. Sometimes, however, a submission's description may be incorrect or incomplete and need to be changed. This article will introduce how to change the version description in Git.

Method 1: Use the "--amend" parameter

When submitting code in Git, you can use the "git commit" command plus the "-m" parameter to add a version description. The format is as follows:

$ git commit -m "这里是版本描述"

If you need to change the submitted version description, you can use the "--amend" parameter, the format is as follows:

$ git commit --amend -m "这里是修改后的版本描述"

This command will pop up an editor to let you edit the new submission information. If you want to save the new submission information and exit the editor, enter ":wq". If you want to cancel the modification, enter ":q!".

It should be noted that if the submission has been pushed to the remote warehouse, it is not recommended to use this method to change the submission information.

Method 2: Use interactive rewrite history

If you need to change the version descriptions of multiple submissions, you can use Git's interactive rewrite history function to achieve this. The following are the specific steps:

1. Use the "git rebase -i" command to open the interactive rewrite history editor, the format is as follows:

$ git rebase -i HEAD~N

"N" is Number of commits to rewrite, "N" is 3 if the last 3 commits are to be rewritten.

2. In the interactive editor, change the keyword of the submission you want to change from "pick" to "edit", and save and exit.

pick 1234567 commit message 1
edit 2345678 commit message 2
pick 3456789 commit message 3

The above example sets the second commit to "edit".

3. Use the "git commit --amend" command and the "git rebase --continue" command to change commit information and continue rewriting history.

$ git commit --amend -m "修改后的版本描述"
$ git rebase --continue

4. Repeat steps 2 and 3 until the version descriptions of all commits to be changed have been modified.
5. Finally use the "git push --force" command to push the modified history to the remote warehouse.

$ git push --force

It should be noted that the interactive rewriting history function can modify the history, so it needs to be used with caution to ensure that it does not affect the code of other developers.

In general, the version description in Git can be modified more easily through the above two methods. Of course, you should also follow good submission practices when using Git to better record code changes and facilitate subsequent collaborative development and code maintenance.
