Git version rollback to Mac?

php editor Xigua teaches you how to use Git on Mac to perform version rollback. Version rollback is a commonly used function in Git, which can help us restore to a previous version when needed to avoid unnecessary errors. On Mac systems, it is also very simple to use Git to roll back versions. It only requires a few simple commands to complete. Next, we will introduce in detail how to use Git to perform version rollback on Mac.

Git code rollback - roll back to the specified version

In short, the git reset command can be used to roll back the version and restore the modifications in the staging area to the workspace. The git reset command is divided into three forms: git reset --hard xxx, git reset --soft xxx and git reset --mixed xxx.

The git reset --hard commit-id command can be used to reset the code base to a specified commit version. Through this command, not only will the branch point be changed, but the files in the working directory and staging area will also be restored to the selected commit state. This mandatory rollback operation should be used with caution as it permanently deletes uncommitted changes, potentially causing data loss.

When rolling back to a specific version number (take 1a2b3c as an example), you can use different parameters to achieve different effects. Using the --hard parameter will cause the changes in the working directory and staging area to be cleared, while using the --soft parameter will retain the contents of the working directory and put the resulting new file differences into the staging area. In addition, there is also a parameter --mixed, which can achieve a mixed effect, that is, retaining the contents of the working directory but clearing the changes in the staging area. Choosing the appropriate parameters depends on how you want to handle the state of the current working directory and staging area. Depending on the specific situation, decide whether to clear the changes or retain the contents of the working directory.

Click "Hard Merge" on the historical node to roll back to a specific version, and click "Soft Merge" on the current node to perform the merge operation. If you need to reset this submission, right-click on the historical node and select "Force Merge". If you need to reset to this submission, right-click on the current node and select "Soft Merge".

Be very careful when using this function, because if you do it carelessly, you may undo other people's submissions. Although you rarely need to use this feature, understanding its principles can help you understand how Git works, including pointer operations between workspaces, staging areas, and repositories. Hope this information is helpful to everyone.

How to roll back git to the previous version

In short, the git reset command can be used to roll back the version and restore the modifications in the staging area to the workspace. The git reset command is divided into three forms: git reset --hard xxx, git reset --soft xxx and git reset --mixed xxx.

When implementing a version rollback operation, you first need to obtain the submission history of the file. Then, copy the hash of the version you want to roll back. Next, use the command git checkout hash filename to check out the version. Finally, commit the checked-out version changes.

Let's check the status of the files in the working directory. As you can clearly see, the working directory is very neat. Therefore, to restore to the previous version, you can only use the git reset --hard command to roll back. We can confirm that the contents of the readme.txt file have been fully restored.

git reset --soft: Roll back to a certain version. Only the commit information is rolled back, and it will not be restored to the index file level.

The smallest unit of git is a commit, so you cannot roll back a file individually. Of course, if there is a submission that only modified one file, you can roll back and just git revert the submission.

gitreset[commit hash value] But this can only roll back the local branch to the commit, and the remote branch is still in its original place.

git rollback to the specified version

The git reset --hard commit-id command can be used to reset the code base to the specified commit version. Through this command, not only will the branch point be changed, but the files in the working directory and staging area will also be restored to the selected commit state. This mandatory rollback operation should be used with caution as it permanently deletes uncommitted changes, potentially causing data loss.

git reset --mixed commit-id command: roll back to the specified version. (soft: mixed, that is: medium rollback.) This command not only modifies the position of the HEAD pointer in the branch, but also rolls back the data in the staging area to the specified version. However, the version in the workspace is still the version before the rollback.

reset is a direct rollback with a specified version. It has two modes. One is to roll back all commits, and the modifications are still there. The other mode is to roll back completely, and the modifications are gone.

Since Git is managed based on trees, it is necessary to ensure that the remote head node is consistent with the local head and obtain the information of a certain historical node locally.

It will take a few days to wait for the jar package to be released again, but at this time there are urgent bugs to be fixed online, so we are in a dilemma. In the end, I decided to roll back the code to version A, and then fix the bugs based on the old version, which started a five-hour journey of suffering.
