Git

Introduction

Git is a distributed revision control system (VCS), designed to work well with highly non-linear workflows. It was initially conceived to support development of the Linux kernel, and has since become the most widely-used VCS for software development.

This page is essentially a cheat-sheet for git commands frequently used by our group.

Basic Git

Basic information to get started with Git can be found at http://rogerdudler.github.io/git-guide/.

Git repository

Is a directory that contains files of the current branch and a hidden .git directory

Contains an Index in .git that acts as a staging area for all your branches

Contains a HEAD in .git that points to the last commit you made

Your PHASTA repository should always be at ~/git-phasta/phasta

Create a new repository

git init

Checkout a repository

git clone /path/to/repository

git clone username@remote-host:/path/to/repository

Add files to be tracked in the git index

git add <filename1> <filename2> ...

git add *

git add -u (all files updated since last commit)

Commit changes to HEAD

git commit -m "my_username: my comments about this commit"

Push changes to remote repo

git push origin master (pushes the master branch to the original/main repo)
