How to quickly restore files in git (a brief analysis of multiple methods)

During our development process, we often encounter situations where we need to restore file modifications. At this time, GIT provides a variety of methods to allow us to quickly restore files.

1. Use the git checkout command

If we only want to discard the modifications of a certain file, instead of discarding all modifications in the entire working directory, we can use the following command:

git checkout -- <file>

Among them, <file> is the name of the modified file. By executing this command, the modifications made to this file will be restored to the state of the latest submission.

2. Use the git reset command

If we not only want to restore the modifications of a certain file, but also want to discard the submitted modifications, we can use the following command:

git reset --hard HEAD

Among them, HEAD is the submission ID of the latest submission. After executing this command, all our submitted modifications will be discarded and restored to the state of the latest submission.

3. Use the git revert command

If we want to undo a submission, but do not want to lose the modifications made by this submission, we can use the following command:

git revert <commit>

Among them, <commit> is the ID of the submission that needs to be revoked. After executing this command, GIT will automatically generate a new submission based on the modifications made by the submission that needs to be revoked. This new submission will Reverse the changes made by the undone commit.

Summary

During the development process, we often need to restore file modifications. GIT provides a variety of methods to meet our needs. We can choose to use the git checkout, git reset or git revert command according to the actual situation. During actual use, we need to note that these commands will modify the history records, so be sure to confirm carefully before use.
