How to edit git

In software development, Git is a widely adopted version control system. By using Git, developers can collaboratively develop and maintain code among multiple team members, and can also record the history of code changes to facilitate backtracking and management. When using Git, we often need to perform some editing operations to handle version control-related tasks. This article will introduce some basic Git editing instructions and operations to help readers better understand how to use Git to manage code projects.

1. What are the basic editing instructions of Git

Git provides a set of basic editing instructions for managing the submission and rollback of code versions. The following are some commonly used instructions:

1. git add: Add files or folders to the staging area. You can use the command 'git add .' or 'git add ' to add single or multiple files to the staging area.
2. git commit: Submit the changes in the current staging area to the local Git repository. Commit messages can be added using the command 'git commit -m "commit message"'.
3. git push: Push the code in the local Git repository to the remote Git repository. You can use the command 'git push ' to specify the remote Git repository and branch.
4. git pull: Pull the latest code from the remote Git repository and merge it into the local branch. You can use the command 'git pull ' to specify the remote Git repository and branch.
5. git checkout: Switch branches or undo changes. You can use the command 'git checkout ' to switch to a specified branch, or use the command 'git checkout ' to undo modifications to a file.

2. How to manage Git code branches

When using Git to manage code, branch management is a very common task. Branches allow us to switch between multiple code versions, try out new features, and isolate different code changes. The following are some commonly used branch management instructions:

1. git branch: List all branches. A new branch can be created using the command 'git branch '.
2. git checkout: Switch to the specified branch. You can use the command 'git checkout ' to switch to a specific branch.
3. git merge: Merge the current branch to the specified branch. You can use the command 'git merge ' to merge the code of the current branch into the specified branch.
4. git stash: Save changes to the current branch and switch to another branch. You can use the command 'git stash' to save changes to the current branch, and the command 'git stash pop' to restore changes.
5. git rebase: Rebase the code of the current branch to the specified branch. You can use the command 'git rebase ' to separate the modifications of the current branch from the specified branch and rebuild the commits based on the specified branch.

3. How to undo changes to the code

When using Git to manage code, we may make some mistakes, such as submitting incorrect code or accidentally deleting some files. . Git provides several methods to undo these bad modifications. Here are some commonly used undo commands:

1. git reset: Go back to a commit and reset the code base to the state of that commit. You can use the command 'git reset ' to backtrack to a specific commit.
2. git revert: Create a new submission, undo the previously submitted changes, and submit the new changes to the code base. You can use the command 'git revert ' to undo a specified commit.
3. git rm: Delete files from the working directory and repository. You can use the command 'git rm ' to delete the specified file.
4. git checkout: Undo modifications to the specified file. You can use the command 'git checkout ' to undo changes to the specified file.

4. How to resolve Git conflicts

When multiple people collaborate or merge branches, code conflicts may occur, for example, two developers modify the same file at the same time. Git provides conflict resolution tools to help us resolve these conflicts. The following are some commonly used instructions for resolving conflicts:

1. git pull: Merge the remote branch and mark the conflict file as pending resolution.
2. git diff: View the differences of conflicting files. You can use the command 'git diff ' to view detailed differences of files.
3. git mergetool: Open the merge tool for conflicting files and manually resolve conflicts. You can use the command 'git mergetool ' to open the merge tool for the specified file.
4. git add: Add conflict-resolving files to the staging area.
5. git commit: Submit files that resolve conflicts.

Summary:

This article introduces how to use Git to edit code, manage branches, undo modifications, and resolve conflicts. By learning these basic instructions and operations, we can better use Git for code management and development. Of course, Git also has many advanced functions and instructions, which require continuous learning and practice.
