Working in a team?Most commercial programming is done in teams

To simplify project management and enforce accountability, version control is used

What is revision control?WITHOUT

If a team creates a bug, it could affect how your code too

You could loose old code or features that were removed

Anyone could add bugs/features to a project and no one would know

WITH

You are isolated on your own branch, so you know who did it

You can go back and see all old version of your project

Someone has to approve your code submission

Lingo The Basics Repository – the database

holding your code Main/Trunk – This is the primary

code Working set – A file you checked

out Tags – the name of the project

stage

Actions Check out – a downloaded file Check in – uploading the file Update – synchronizes your code Revert – toss the changes you

made

More complicated Branch – create a separate copy

of a file or folder Diff – (I bet you know) Merge – combining branches

But how does one “branch”?

That’s how Linux is made(kinda)
