Basics

Git is a Distributed Version Control System (DVCS).

Local Operations

Working directory: Files where you work

Staging Area: Staged diffs are ready to be committed

git repository: Committed files

Config

System (/etc/gitconfig): git config --system

Global (~/.gitconfig): git config --global

Repository (%WORKINGDIRECTORY%/.git/config): git config --local

Ignoring files

In workingdirectory:

vim .gitignore

Working local

Clone existing Repository

git clone git://github.com/schacon/grit.git

That creates a directory named "grit", initializes a .git directory inside it, pulls down all the data for that repository, and checks out a working copy of the latest version

git clone git://github.com/schacon/grit.git mygrit

Creates "mygrit" directory instead of "grit"

Check Status

git status

Show log

git log

oder

gitk

git log --stat

Mit Zusammenfssung der Änderungen

Formatting output

git log --pretty=oneline

git log --pretty=format:"%h - %an, %ar : %s"

git log --pretty=format:"%h %s" --graph

Limit output

git log --since=2.weeks

git log --2

git log --pretty="%h - %s" --author=gitster --since="2008-10-01" --before="2008-11-01" --no-merges

Stage files

A modified file under version control can be staged with the command

git add

or use

git gui

git add is also used to add new files to version control.

Commit files

git commit

git commit -m 'initial project version'

Remove files

git rm readme.txt

deletes the readme.txt file from working directory (file is really deleted) and from version control.

git rm --cached readme.txt

deletes the readme.txt file from version control, but not from working directory (file is still on filesystem).

Working with Remotes

You must have cloned an existing Repository before working with remotes. See Clone existing Repository

Show remote repositories

git remote

git remote -v

Adding Remote Repositories

git remote add mic git@git.imis.intra:~mic/ishop-ap/mic-ishop-ap.git

Update repository

gets all changes from mic without merge:

git fetch mic

git fetch origin

gets all changes from mic and merges to current branch (or master):

git pull origin

Pushing to Remotes

git push [remote-name] [branch-name]

git push origin master

Pushes your master branch to your origin server

Inspecting a Remote

git remote show origin

Tagging

List tags

git tag

git tag -l '2.0.*'

lists only tags matching '2.0.*'-pattern

Create tags

lightweight (eg. for temporary use): like a branch that doesn’t change — it’s just a pointer to a specific commit
annotated (recommended): are stored as full objects in the Git database. They’re checksummed, contain the tagger name, e-mail, and date, have a tagging message;

Annotated

git tag -a v1.4 -m 'my version 1.4'

Lightweight

git tag v1.4-1
