Git is a commonly used version control tool that can help developers better manage their code. In the process of using Git, some unexpected situations may occur, such as adding unnecessary files or missing some files that need to be added.
In this case, we need to learn how to discard files that have not been added to avoid unnecessary submissions.
1. Concept introduction
In Git, we often use the following two commands to manage files:
Therefore, when discarding files that have not been added, we need to understand the concept of the temporary storage area.
The staging area (also known as the index) is a special area in Git that is used to temporarily store the changes we make until we are ready to commit them. This means that changes can only be committed after they have been added to the staging area via the git add command.
2. How to discard files that have not been added yet
Here are several ways to discard files that have not been added yet:
The git stash command can store all uncommitted changes into a stack. Using this command, we can clear the working directory and restore the code to the state of the last commit. The following are the specific steps:
(1) Use the git status command to view unadded files;
(2) Use the git stash command to save uncommitted changes to the stack;
(3) Use the git stash drop command to delete the saved changes in the stack;
(4) Use the git stash apply command to re-apply the saved changes to the current branch.
If you just want to delete some files in the working directory without restoring the code to the previous commit state, you can use git checkout Order. The following are the specific steps:
(1) Use the git status command to view unadded files;
(2) Use the git checkout command to delete unadded files.
If you want certain files to never be added to the Git repository, you can use a .gitignore file to specify these files. The following are the specific steps:
(1) Create a file named .gitignore;
(2) List the files that you do not want to add to the Git repository in the .gitignore file;
(3) Run the git rm --cached command to delete the files that have been added in the Git warehouse from the cache;
(4) For the files that have not been added, these files will be Ignored and excluded from Git repositories.
Summary
The above are three methods of discarding files that have not been added. The most commonly used one is to use the git stash command. However, it should be noted that when using the git stash command, only changes stored in the stack will be retained. Therefore, before clearing the working directory, make sure you have saved all critical changes.
Using the above command to discard files that have not been added can help us better manage the code and avoid unnecessary submissions. Deepening our understanding of the staging area is also very important for us to use Git better.
