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

Excel file To complete this article, we need four steps: 1. Data: Here I use static data to ensure that this article is as easy as possible. 2. Set: static data is saved in the set. 3. DataTable: Convert the data of the generic set and save it to the DataTable. 4.
