Git Log Viewing: log Command Parameters and Commit History Analysis
This article introduces the importance and usage of Git logs. Viewing Git logs allows you to understand commit records (who, when, and what was modified), project iteration trajectories, and also helps in locating issues. The basic command `git log` displays commit IDs, authors, times, and commit messages. Common parameters include: `--oneline` for simplified display, showing one commit per line; `-p` to display code differences (diff); `-n` to limit the number of commits (e.g., `-n 3`); `--graph` for graphical representation of branch merges; `--author` to filter by author, `--since`/`--before` to filter by time range; and `--color` for colored output. When analyzing logs, you can quickly pinpoint issues and understand branch logic. Clear commit messages (e.g., "Fix login button") can enhance collaboration efficiency. Mastering these parameters is key to efficient version control.
Read MoreGit Common Commands Quick Reference: Remember These 10 Commands, Git Operations Will Be Easy
This article introduces 10 core and commonly used Git commands to help beginners quickly master basic operations. The core commands cover the complete workflow from initialization to collaboration: - **Initialization/Clone**: `git init` initializes a local repository, and `git clone` copies code from a remote repository; - **Modify and Commit**: `git add` stages changes (use `.` for a single file or entire directory), and `git commit -m "message"` commits to the local repository (with clear commit messages); - **Status and History**: `git status` checks repository status, and `git log` views commit history (`--oneline` for a concise format); - **Branch Management**: `git checkout -b branch-name` creates and switches to a branch, and `git merge branch-name` merges branches (note conflict handling); - **Collaboration Operations**: `git pull` fetches and merges remote code, and `git push origin branch-name` pushes a local branch to the remote. The core workflow is: Initialize/Clone → Stage modifications (add) → Commit → Branch management → Collaboration (pull/push). Beginners can gradually become proficient through practice, reducing version management chaos.
Read MoreDiagram of Common Git Operations: Complete Steps from Clone to Commit
This article introduces the basic operation process for Git beginners from cloning a repository to committing modifications. First, clarify three core areas: the working directory (unmanaged modified files), the staging area (a temporary storage area for commits), and the local repository (permanently records commit history). The process includes: 1. Cloning a remote repository (`git clone <URL>`); 2. Entering the directory and checking status (`git status`); 3. Modifying files (working directory operations); 4. Staging modifications (`git add [filename]` or `git add .`); 5. Committing to the local repository (`git commit -m "message"`); 6. Viewing commit history (`git log`); 7. Pushing to the remote repository (`git push origin [branch]`). A quick-reference cheat sheet for key commands summarizes core operations, emphasizing that Git enables collaboration and version management by tracking changes, with regular practice allowing rapid mastery of the basic workflow.
Read MoreGit Distributed Version Control: Why Every Developer Needs a Local Repository
This article introduces the importance of local repositories in the Git version control system. Version control can record code modifications and avoid chaos. As a distributed tool, Git differs from centralized systems like SVN with its "central server" model, as each developer maintains a complete local code repository. A local repository is the `.git` directory on a computer, with core functions: it is offline-accessible, allowing commits and branch operations without an internet connection; it supports experimentation by safely testing new features in local branches; and it ensures data security by automatically backing up all modifications, preventing code loss due to server failures or power outages. Its value lies in: independence from the network, enabling more flexible work (e.g., writing code without internet access on the subway); preventing accidents, as rollbacks can be performed via commands like `git reset`; and enhancing collaboration efficiency by allowing local completion of features before pushing to the remote repository. The local repository is the core of Git's distribution model, and developers should attach importance to it (e.g., initializing with `git init`), as it is crucial for ensuring development flexibility and reliability.
