Working with Git & Github? Cheatsheet
This graph might help you to understand much easier each command to backup your code, notes, etc and collaborate with other ongoing projects.
-- SETUP --
Configuring user information used across all local repositories
# set a name that is identifiable for credit when review 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
-- SETUP & 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 working directory, staged for 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 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 into your working directory
$ git checkout
# merge the specified branch’s history into the current one
$ git merge [branch]
# show all commits 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 project and stage the removal for commit
$ git rm [file]
# change an existing file path and stage the move
$ git mv [existing-path] [new-path]
# show all commit logs with indication of any paths that moved
$ git log --stat -M
-- SHARE & UPDATE --
Retrieving updates from another repository and updating local repos
# add a git URL as an alias
$ git remote 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 current branch ahead of specified one
$ git rebase [branch]
# clear staging area, rewrite working tree from specified commit
$ git reset --hard [commit]-
