Git

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

Basics

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

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

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).

Commands

git commit -m 'initial project version'
