How to restore modified files in git

In the daily development process, we often need to modify the code. However, sometimes we make mistakes and fail to modify the code, causing the program to crash. What should we do at this time? Do I have to write it again? Don't worry, git provides the function of restoring modified files. Let's take a look at how to use it.

Step one: View modified files

After modifying the code, we can use the following command to view which files have been modified:

git status

In In the output of this command, we can see all modified files. At this time, we need to restore a certain file back to its previously modified state.

Step 2: Restore the modified file

Use the following command to restore a modified file:

git checkout 文件名

Note that you need to be careful when using this command to avoid Misoperation leads to code loss. After execution, we can use git status to check the current status of the file. If the restore is successful, a prompt similar to "nothing added to commit but untracked files present" should appear.

Step 3: Submit the restored changes

Use the following command to submit the restored changes to the local git library:

git add 文件名
git commit -m "还原修改的文件"

Here we can use the restored changes as One commit. Of course, if you need to make further modifications to the file, you can do it directly after the restore.

Finally, we need to note that git restores file modifications rather than deletions. In other words, if we delete a file, we need to use other commands to restore it. When using git to restore, we must also pay attention to avoid misoperation, otherwise it will damage our code base and cause various unpredictable problems.
