release and communication of the source code is extremely convenient. Git is fast, and it's naturally important for big projects like Linux kernel. The best of Git is its combined tracking (merge tracing) capability.Install git command: # apt-get install git and # apt-get install Git-doc git-svn git-email Git-gui gitk.This chapter shows you how to create a repository, submit source code, create a branch, upload source code to a remote server, and get

If the environment is a single user logon, and the files are shared by the server, it is also a good choice
