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.
