After a concentrated development and debugging session you are likely to forget all the changes you've made.  The >git status command will remind you.
Checking the status of a git repository
How to do it...
The git status command reports the current status of your project. It will tell you what branch you are on, whether you have uncommitted changes and whether you are out of sync with the origin repository:
$ git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) ...
