Git vs SVN: Core Differences, Workflow Concepts, and Essential Commands

Git vs SVN Overview – Git is a distributed version control system while SVN is centralized, which makes Git capable of offline work and cheap branching, whereas SVN requires network access and treats branches as costly directory copies.

Complexity – Git offers many commands (e.g., git add , git commit , git status , git fetch , git push , git rebase , git merge , git cherry-pick , git submodule , git stash ) and concepts (rebase vs merge, local vs remote repositories), which provide powerful features but have a steeper learning curve compared to SVN’s simpler command set.

Branching – In Git a branch is a lightweight pointer to a commit, enabling fast, cheap branch creation and local branches; in SVN a branch is a full directory copy, making branch operations slower and more expensive.

Git Core Workflow

Workspace (working directory)

Index (staging area)

Repository (local and remote)

Typical commit steps:

git add . – stage all changes

git commit -m "message" – create a commit in the local repository

git push or git svn dcommit – send commits to the remote repository

Git‑SVN Bridge – The git svn command set allows Git to interact with an SVN server, enabling users to clone an SVN project into a Git repository, fetch updates, rebase, and dcommit back to SVN.

Common Git‑SVN Commands

# Clone an SVN project as a Git repo
$ git svn clone -s [repository]
# Show repository info
$ git svn info
# Fetch SVN changes
$ git svn fetch
# Rebase local branch onto SVN
$ git svn rebase
# Commit changes back to SVN
$ git svn dcommit

Git Initialization and Configuration

# Initialize a new Git repository
$ git init
# List all config values
$ git config -l
# Set user name and email
$ git config --global user.name "Your Name"
$ git config --global user.email "[email protected]"

File Operations

# Add files
$ git add
# Remove files and stage the removal
$ git rm
# Stop tracking a file but keep it locally
$ git rm --cached
# Rename a file
$ git mv

Branch Management

# List branches
$ git branch
$ git branch -a
# Create a new branch
$ git branch
# Create and switch to a new branch
$ git checkout -b
# Switch branches
$ git checkout
# Merge a branch
$ git merge
# Delete a branch
$ git branch -d
# Delete a remote branch
$ git push
:

Commit Operations

# Commit staged changes
$ git commit -m "msg"
# Amend the previous commit
$ git commit --amend -m "new msg"
# Push to remote
$ git push

Fetching and Pulling

# Fetch changes
$ git fetch
# Show remote info
$ git remote -v
# Pull (merge) changes
$ git pull
# Pull with rebase
$ git pull --rebase

Reset, Revert, and Stash

# Reset to a specific commit (hard)
$ git reset --hard
# Revert a commit
$ git revert
# Stash uncommitted changes
$ git stash
# Apply stash
$ git stash pop

Querying

# Show status
$ git status
# Show diff
$ git diff [file]
# Show staged diff
$ git diff --cached [file]
# View commit log
$ git log
# Show a specific commit
$ git show

Overall, mastering these commands and concepts enables developers to choose the appropriate workflow, leverage Git’s powerful branching and offline capabilities, or integrate with existing SVN repositories using the Git‑SVN bridge.
