Git hub - Quick Start Reference



Hello Buddies,

Sharing a quick-start reference which I came across while working with Git repo.





Here are some quick commands -



CONFIGURE TOOLING
Configure user information for all local repositories -

$ git config --global user.name "[name]"
Sets the name you want attached to your commit transactions

$ git config --global user.email "[email address]"
Sets the email you want attached to your commit transactions

$ git config --global color.ui auto
Enables helpful colorization of the command line output



CREATE REPOSITORIES
Start a new repository or obtain one from an existing URL -

$ git init [project-name]
Creates a new local repository with the specified name

$ git clone [url]
Downloads a project and its entire version history



MAKE CHANGES
Review edits and creates a commit transaction -

$ git status
Lists all new or modified files to be committed

$ git add [file]
Snapshots the file in preparation for the versioning

$ git reset [file]
Un-stages the file, but preserves its contents
$ git diff

Shows file differences that are not yet staged
$ git diff --staged

Shows file differences between the staging and the last file version
$ git commit -m "[descriptive message]"

Records file snapshots permanently in the version history



GROUP CHANGES
Name a series of commits and combine completed efforts -

$ git branch
Lists all the local branches in the current repository

$ git branch [branch-name]
Creates a new branch

$ git checkout [branch-name]
Switches to the specified branch and updates the working directory

$ git merge [branch]
Combines the specified branch’s history into the current branch

$ git branch -d [branch-name]
Deletes the specified branch



REFACTOR FILENAMES
Relocate and remove versioned files -

$ git rm [file]
Deletes the file from the working directory and stages the deletion

$ git rm --cached [file]
Removes the file from version control but preserves the file locally

$ git mv [file-original] [file-renamed]
Changes the file name and prepares it for the commit



REVIEW HISTORY
Browse and inspect the evolution of project files -

$ git log
Lists version history for the current branch

$ git log --follow [file]
Lists version history for a file, including renames

$ git diff [first-branch]...[second-branch]
Shows content differences between the two branches

$ git show [commit]
Outputs metadata and content changes of the specified commit



SUPPRESS TRACKING
Exclude temporary files and paths -
*.log build/ temp-*

A text file named .gitignore suppresses accidental versioning of files and paths matching the specified patterns

$ git ls-files --other --ignored --exclude-standard
Lists all ignored files in this project



REDO COMMITS
Erase mistakes and crafts replacement history -

$ git reset [commit]
Undoes all commits after [commit], preserving changes locally

$ git reset --hard [commit]
Discards all history and changes back to the specified commit



SAVE FRAGMENTS
Shelve and restore incomplete changes -

$ git stash
Temporarily stores all modified tracked files

$ git stash list
Lists all stashed changesets

$ git stash pop
Restores the most recently stashed files

$ git stash drop
Discards the most recently stashed changeset



SYNCHRONIZE CHANGES
Register a repository bookmark and exchange version history -

$ git fetch [bookmark]
Downloads all the history from the repository bookmark

$ git merge [bookmark]/[branch]
Combines bookmark’s branch into the current local branch

$ git push [alias] [branch]
Uploads all the local branch commits to GitHub

$ git pull
Downloads bookmark history and incorporates the changes
