Git · Basic Workflow
Syntax
git status [-s]
Example
git status
git status -s
Output
On branch main
Changes not staged for commit:
  modified:   app.js
Untracked files:
  utils.js

# Short format:
 M app.js
?? utils.js

Note The short flag (-s) gives a compact two-column output: left column = staging area, right column = working tree. M = modified, A = added, ? = untracked, D = deleted.
