Without Version Control
How it works
Track all files in a directory (repository)
Identify line-by-line changes
Take snapshots of your files
Share to the cloud for collaboration
Git
Version control software
Free and open source
Enable new terminal commands
Industry standard
Locally
Initialize a project
Add files to track
Take a snapshot/checkpoint of your work
git init
git add *
git commit -m "..."
Repeat these steps each time you make changes
git init
Run in the directory of your project
Creates a hidden .git file that track changes
Allows you to perform other git commands, like git status
git add
Adds files to be tracked in the future
Adds changes to already tracked files
One file (git add filename.r) or all files (git add *)
git commit
Takes a snapshot of added changes
Must include a message (git commit -m "message here")
{but what's GitHub?}
git init
git add *
git commit -m "message"
