Git is the free and open-source distributed version control system.
Installation & GUIS
GitHub for Windows
GitHub for Mac
GitHub for All Platforms
Setup
Configuring user information used across all local repositories
Set a name that is identifiable for credit when reviewing the version history
git config –global user.name “[firstname lastname]”
Set an email address that will be associated with each history marker
git config –global user.email “[valid-email]”
Set automatic command line coloring for Git for easy reviewing
git config –global color.ui auto
Init
Configuring user information, initializing and cloning repositories
Initialize an existing directory as a Git repository
git init
Retrieve an entire repository from a hosted location via URL
git clone [url]
Stage & Snapshot
Working with snapshots and the Git staging area
Show modified files in the working directory, staged from your next commit
git status
Add a file as it looks now to your next commit (stage)
git add [file]
Unstage a file while retaining the changes in the working directory
git reset [file]
Diff of what is changed but not staged
git diff
Diff of what is staged but not yet committed
git diff –staged
Commit your staged content as a new commit snapshot
git commit -m “[descriptive message]”
Branch & Merge
Isolating work in branches, changing context, and integrating changes
List your branches.a*will appear next to the currently active branch
git branch
Create a new branch at the current commit
git branch [branch-name]
Switch to another branch and check it out in your working directory
git checkout
Merge the specified branch’s history into the current one
git merge [branch]
Show all commit in the current branch’s history
git log
Inspect & Compare
Examining logs, diffs, and object information
Show the commit history for the currently active branch
git log
Show the commits on branchA that are not on branchB
git log branchB..branchA
Show the commits that changed file, even across renames
git log –follow [file]
Show the diff of what is in branchA that is not in branchB
git diff branchB…branchA
Show any object in Git in human-readable format
git show [SHA]
Tracking Path Changes
Versioning file removes and path changes
Delete the file from the project and stage the removal for the commit
git rm [file]
Change an existing file path and stage the move
git mv [existing-path] [new path]
Show all commit logs with an indication of any paths that moved
git log –stat -M
Ignoring Patterns
Preventing unintentional staging or committing of files
Save a file with desired patterns as .gitignore with either direct string matches or wildcard globs.
logs/
*.notes
pattern*/
System-wide ignore pattern for all local repositories
git config –global core.excludesfiles [file]
Share & Update
Retrieving updates from another repository and updating local repos
Add a git URL as an alias
git remotes add [alias] [url]
Fetch down all the branches from that Git remote
git fetch [alias]
Merge a remote branch into your current branch to bring it up to date
git merge [alias]/[branch]
Transmit local branch commits to the remote repository branch
git push [alias] [branch]
Fetch and merge any commits from the tracking remote branch
git pull
Rewrite History
Rewriting branches, updating commits, and clearing history
Apply any commits of the current branch ahead of the specified one
git rebase [branch]
Clear staging area, rewrite working tree from the specified commit
git reset — hard [commit]
Temporary Commits
Temporarily store modified, tracked files in order to change branches
Save modified and staged changes
git stash
List stack-order of stashed file changes
git stash list
Write working from the top of the stash stack
git stash pop
Discard the changes from the top of the stash stack
git stash drop
