Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.
As an example we'll use the ''awesome'' group, administrative user (set up by HPC staff) ''admin'' and a regular user ''student''.
 
===admin@linux64===
 
The admin user on a remote machine ''linux64'' can do the following
 
* Check out the admin repository
 
git clone awesome@git.hpc.ufl.edu:gitosis-admin.git
 
* Add more users e.g. 'student' with a  public key ''student.pub''
 
cd gitosis-admin
 
cp ~/student.pub keydir/
 
git add keydir/*
 
git commit -m "added user student"
 
git push
 
* Create a new repository ''denovo'' for ''de novo'' assembly scripts and set access to users ''admin'' and ''student''
 
cd gitosis-admin
 
vim gitosis.conf
 
Add:
 
[group awesome]
 
writable = denovo
 
members = admin student
 
* Commit and push
 
git add *
 
git commit -m "Set up a new repository denovo for use by admin and student"
 
git push
 
* Create a local working tree for the ''denovo'' project:
 
cd
 
mkdir denovo
 
cd denovo
 
git init
 
git remote add origin awesome@hpc.ufl.edu:denovo.git
 
* Add and edit some files
 
* Commit and push to the Git server
 
git add *
 
git commit -m "Initial import"
 
git push origin master

Description

git website  

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Git is easy to learn and has a tiny footprint with lightning fast performance. It outclasses SCM tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.

Environment Modules

Run module spider git to find out what environment modules are available for this application.

System Variables

  • HPC_GIT_DIR - installation directory


Additional Information

UFRC git environment module also contains a 'git-lfs' instance, so you can run 'git lfs ...' after loading the git environment module.
