Create a new git project / initialize git:
git init
What's the status in this git project?
git status
Green means: it has been staged for commit (git knows this change).
Red means: it has not been staged and would not be committed.
See what changed:
git diff
Add a change to git for the next commit:
This command stages the changed file for the next commit.
git add <filename>
If you worked on the file index.html and you want to add it, you would do it with:
git add index.html
Add all files that you have been working on:
git add .
Make a git commit:
git commit
This will open vim, and will ask you to type a commit message. Write the commit message and close with :x.
If you don't want to use vim, you can use the command:
git commit -m "Your commit message"
It is good practice to choose a commit message that is simple and describes precisely what has been changed.
See the history of commits:
git log
