Git Cheat Sheet

Git System

Remote Execution

Basic commands

=================

Initialize an existing directory as a Git repository

$ git init
Initialized empty Git repository in C:/Users/Admin/Documents/Git/.git/

Show modified files in working directory, staged for your next commit

$ git status
On branch master

No commits yet

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        Readme.md
        image.jpg

nothing added to commit but untracked files present (use "git add" to track)

Add a file as it looks now to your next commit (stage)

$ git add Readme.md image.jpg 

Commit your staged content as a new commit snapshot

$ git commit -m "First Commit"
[master (root-commit) 784ae2e] First Commit
 Committer: unknown <Admin@FOR209-03.irisib.lan>
Your name and email address were configured automatically based
on your username and hostname. Please check that they are accurate.
You can suppress this message by setting them explicitly:

    git config --global user.name "Your Name"
    git config --global user.email you@example.com

After doing this, you may fix the identity used for this commit with:

    git commit --amend --reset-author

 2 files changed, 61 insertions(+)
 create mode 100644 Readme.md
 create mode 100644 image.jpg

Set a name & email that is identifiable for credit when review version history

$ git config --global user.name “[firstname lastname]”

$ git config --global user.email “[valid-email]”

Show all commits in the current branch’s history

$ git log
commit 784ae2e2d10720c23eb7cebdf8386ef2157fe628 (HEAD -> master)
Author: unknown <Admin@FOR209-03.irisib.lan>

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]

git pull

fetch and merge any commits from the tracking remote branch

BRANCH & MERGE

Isolating work in branches, changing context, and integrating changes

git branch

list your branches. a * will appear next to the currently active branch

git branch [branch-name]

create a new branch at the current commit

git checkout

switch to another branch and check it out into your working directory

git checkout -b|-B <new_branch> []

Specifying -b causes a new branch to be created as if git-branch(1) were called and then checked out.

If -B is given, <new_branch> is created if it doesn’t exist; otherwise, it is reset. This is the transactional equivalent of

git merge [branch]

merge the specified branch’s history into the current one

git log

show all commits in the current branch’s history

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

Setup

Configuring user information used across all local repositories

git config --global user.name “[firstname lastname]”

set a name that is identifiable for credit when review version history

git config --global user.email “[valid-email]”

set an email address that will be associated with each history marker

git config --global color.ui auto

set automatic command line coloring for Git for easy reviewing

Saving your uncommitted work for a quick fix then getting it back

git stash

temporarily stash your work since your last commit

git stash pop

fetch your stashed work to continue it

$ git stash pop stash@{2}

in case you want to apply a specific Stash item (not the most recent one), you can provide the index name of that item in the "pop" option

Rewriting history

git commit --amend -m "New commit message"

replace the last commit

git commit --amend --no-edit

replace the last commit without changing the commit message

git rebase -i {branch}

take the precedent commit and add it to your branch

Ignoring files

touch .gitignore && echo {what you want to ignore} >> .gitignore

create a file and specify what (extensions, directories, files) to ignore in it

git rm --cached {fileignored}

remove from the tracking index a file that should be ignored but wasnt because already tracked when the ignore rule was created
