Highlight #1: Git
Git is what is known as a version control system. It is used to track the changes made to computer files and coordinate the work done on those files by multiple people. It can be used to keep track of changes made to any type of file but it is primarily used for source code management by software developers. Git Hub is what is known as a distributed control version system which focuses on speed, data integrity, and support. Every Git directory is a repository that contains a complete history of all changes and complete tracking abilities. Git is an open source software and is distributed for free.
Highlight #2: Remote Repository
A remote repository is essentially a copy of the repository the user is currently working in which allows the user to push changes made to a file in one repository to another. The remote repository is hosted on the git hosting service GitHub. Typically, in a project there is one remote repository and it is known as the central repository. The remote repository can be cloned to other computers and changes can be made by others but the changes will not affect the original repository unless the changes are pushed up to central repo and pulled down to the original machine. The benefit of having the remote repository is that any project can be reverted to a previous orm because snapshots of every change are made.
Highlight #3: Local Repository
The local repository is the reference to the copy of the files that are on the machine you are currently working and pushing to eventually be committed. Changes made here can be deleted. This local repository has all the same capabilities as the remote repository. Changes made to files must be pushed and committed to the remote repository to save the snapchats. The local repository is what contains the working directory and the staging area, where pushed files remain until committed. This is the repository where commands like git add, git push, git commit, git merge, and git checkout will be used.
Highlight #4: Version Control System
Version Control is a system that records all changes, modifications, and alterations made to a file or set of files. GitHub is a version control system that is designed to do this while allowing for collaboration among a few or even many contributors. These systems have a central repository that holds all the files and users of the system checkout the files they need to work on, make changes on their own local repository on their own machine, the push and commit those changes back to the central repository. Snapchats of the files are kept every step of the way so that files can be reverted to a previous form.
Highlight #5: Commit Command
The commit command is expressed as git commit in the git language. This is the command that basically just records all changes to a repository. While it sounds simple, this is one of the most and essential commands in git. It stores all current changes in a new commit into a repository with a log that has a description of all the changes from the user. The commit command is used in junction with many options such as git commit –a, which tells the command to automatically stage all files that have been modified and deleted. Many other options are aviliable that tell the git commit command to perform many actions.
