D9 - basic git workflow

the basic workflow includes:

• editing the file
• staging the file
• committing the file

working area is where changed files are

running git status, the files in the working area are shown as 'untracked files'

the files here are not tracked or saved to git

git add moves it to the index or the staging area

this is where git starts tracking and saving changes

git commit sends the staged changes to the local repository

this adds a checkpoint that compiles all the changes

git log can be used to view previous commits

git diff shows all the differences between a file in the staging area and the edits in the working area

it can also be used to view differences between two branches

git push pushes the local repository changes to the hosting service

conversely, git pull pulls code from the hosting service to the local repository

to move changes from index to the working area, ie. un-stage changes, use git rm <filename> --cached

using git rm <filename> permanently deletes the changes

git mv <source> <destination> can be used to move or rename a file
